Fluoride is a type of the chemical element fluorine. It happens naturally in nature and is discovered in body tissues containing calcium, such as bones and teeth.

Fluoride protects teeth from the germs in plaque. It also promotes new bone development. This is various than most medications used for weak bones (osteoporosis), which combat osteoporosis by keeping bone from being broken down.

People typically utilize fluoride to prevent cavities. It is likewise utilized for tooth plaque, a mild kind of gum disease (gingivitis), osteoporosis, and numerous other conditions, but there is no good clinical proof to support most of its other uses.

The FDA alerts that swallowing too much tooth paste can increase the threat for tooth staining. But this is likely more of a worry about long-lasting usage rather than mistakenly swallowing it simply as soon as. Likewise, beginning June 2022, fluoride levels in mineral water can not surpass 0.7 mg per liter and must be declared on the label. [2]

History of fluoride

When it comes to the world of oral health, we talk about fluoride regularly. And although the majority of parents know it’s good for their children’s teeth, they may not know why. When your child eats sugary foods, bacteria in their mouths produce acid that can eat away at the minerals on the surface of the teeth. This makes them weaker and increases the chances of developing cavities. Fluoride has actually been shown to protect teeth from this decay and can even help rebuild the tooth’s surface! This mineral is the best cavity fighter we need to assist keep your entire household’s teeth healthy and strong.

Fluoride is most efficient when it originates from both internal and external sources. It can be gotten in 2 types: topical and systemic. Topical fluorides are applied directly to the tooth enamel through fluoride tooth pastes, mouth rinses, and fluoride treatments in an oral office like Children’s Dental Center. Especially for kids who are at a moderate-to-high danger of developing cavities, the expert fluoride treatments our dentists supply might be suggested every three or 6 months. The fluoride in this treatment is available in a varnish and usually only takes a few moments to apply to the teeth. Your child might be asked not to consume or drink for at least thirty minutes afterward to enable their teeth to soak up the fluoride and help repair any microscopic areas of damage.

Systemic fluoride is consumed through sources like fluoridated water and dietary fluoride supplements. Water fluoridation offers regular and consistent contact with low levels of fluoride. All water consists of some fluoride, and some groundwater and natural springs can have naturally high levels. However, most water won’t have adequate naturally happening fluoride to prevent tooth decay. Many cities and counties will include and adjust the levels of fluoride found in their water in order to accomplish the optimum preventative benefits. This community water fluoridation is the most affordable approach of delivering fluoride to a great deal of people and can lower dental caries by as much as 25% in children and grownups.

In addition to a good oral hygiene routine and routine dental visits, fluoride can assist keep your kid’s teeth healthy and strong throughout their lives. But how did we pertain to discover its benefits? What caused including it in everyday items like toothpaste, or including it to our water products? Let’s have a look at the history of fluoride to discover more!

How fluoride wound up in our supply of water

Like much of contemporary medicine, fluoride was come across by chance. In the early 1900’s, a dental professional by the name of Frederick McKay saw that nearly 90% of the population of a particular Colorado town had strange brown staining on their teeth. He welcomed fellow dental practitioner G.V. Black to team up with him on discovering the cause of this phenomenon. Through their research, they found that the staining was the result of flaws in the advancement of the tooth enamel, what is now called fluorosis. They also found that individuals affected by this staining were remarkably resistant to tooth decay.

Eventually, McKay had the ability to trace the source of this staining to the local water system. Thanks to substantial natural fluoride deposits throughout the Western US, the water in this particular Colorado town was especially abundant in fluoride. Nevertheless, it wasn’t up until the 1940s that this knowledge was used towards reinforcing teeth. The Grand Rapids water fluoridation study was a project spanning fifteen years, during which researchers monitored the rate of dental caries among nearly 30,000 schoolchildren. After a years, they discovered that the rate of cavities had actually decreased by 60% among Grand Rapids kids who were born after water fluoridation began. Based upon the success of this pilot research study, numerous states made the decision to move forward with public water fluoridation programs, reducing the rates of tooth decay amongst their people, and enhancing their overall oral health. Water fluoridation is cost-efficient, even for little communities, and conserves both households and the healthcare system money.

Due to the predominance of acid-producing bacteria triggered by our modern-day diet, fluoride has actually ended up being essential to protect the teeth versus daily overuse. Currently, about 75% of the United States population are served by neighborhood water systems that contain enough fluoride to secure their teeth. However, approximately 100 million Americans still do not have access to water with fluoride. Due to the fact that it has proven benefits, the United States has actually set a nationwide objective for 80% of Americans to have water with sufficient fluoride to prevent dental caries by 2020.

Topical application of fluoride

Water fluoridation programs are an incredibly crucial approach of enhancing our oral health, but they are still an outcome of the initial research done by McKay and his coworkers. More just recently, scientists have actually found that the protective components of fluoride are gotten from direct contact with the tooth enamel, toughening it and safeguarding it versus acid. The topical application of fluoride from oral rinses, tooth pastes, and professional fluoride treatments has actually been shown to perform more efficiently than the systemic shipment of fluoride through treated water.

A word on fluorosis

Systemic delivery can produce some negative effects at high doses, well above what you would discover in public water products. Fluoride, like any mineral, can be bad for you if you take in too much. Generally, tarnished spots and brown staining of the tooth enamel are the most typical indication of excessive fluoride consumption.

The advantages fluoride offers kids can’t be beat! This assists set them up for a strong, healthy smile throughout their life. For children ages 1-8, fluoride assists to strengthen the adult teeth that are establishing under the gums. For older children, fluoride supports tooth enamel and can help restore it in certain cases. This results in fewer and less severe cavities, less need for fillings and tooth removal, and less tooth decay in general. [3]


Fluorine is estimated to be the 13th-most abundant element in Earth’s crust and is commonly distributed in nature, entirely in the form of fluorides. The large majority is held in mineral deposits, the most commercially important of which is fluorite (CaF2). Natural wear and tear of some sort of rocks, as well as human activities, releases fluorides into the biosphere through what is often called the fluorine cycle.

In water

Fluoride is naturally present in groundwater, fresh and saltwater sources, in addition to in rainwater, especially in city areas. Seawater fluoride levels are normally in the variety of 0.86 to 1.4 mg/L, and typical 1.1 mg/L (milligrams per liter). For comparison, chloride concentration in seawater has to do with 19 g/L. The low concentration of fluoride shows the insolubility of the alkaline earth fluorides, e.g., CaF2.

Concentrations in fresh water vary more substantially. Surface water such as rivers or lakes generally includes between 0.01– 0.3 mg/L. Groundwater (well water) concentrations differ a lot more, depending on the presence of regional fluoride-containing minerals. For example, natural levels of under 0.05 mg/L have actually been detected in parts of Canada however up to 8 mg/L in parts of China; in general levels hardly ever go beyond 10 mg/liter.

In parts of Asia the groundwater can contain dangerously high levels of fluoride, resulting in serious illness.

Worldwide, 50 million people get water from water supplies that naturally have near to the „optimal level“.

In other locations the level of fluoride is extremely low, sometimes resulting in fluoridation of public water supplies to bring the level to around 0.7– 1.2 ppm.

Mining can increase regional fluoride levels.

Fluoride can be present in rain, with its concentration increasing significantly upon exposure to volcanic activity or climatic contamination originated from burning nonrenewable fuel sources or other sorts of market, especially aluminium smelters.

In plants

All vegetation consists of some fluoride, which is soaked up from soil and water. Some plants focus fluoride from their environment more than others. All tea leaves consist of fluoride; however, mature leaves consist of as much as 10 to 20 times the fluoride levels of young leaves from the same plant.

Chemical properties


Fluoride can serve as a base. It can integrate with a proton (H+):.

F − + H+ → HF.

This neutralization response forms hydrogen fluoride (HF), the conjugate acid of fluoride.

In liquid option, fluoride has a pKb worth of 10.8. It is therefore a weak base, and tends to remain as the fluoride ion instead of producing a substantial quantity of hydrogen fluoride. That is, the following stability favours the left-hand side in water:.

Nevertheless, upon prolonged contact with moisture, soluble fluoride salts will decompose to their particular hydroxides or oxides, as the hydrogen fluoride gets away. Fluoride stands out in this regard amongst the halides. The identity of the solvent can have a remarkable impact on the stability moving it to the right-hand side, significantly increasing the rate of decomposition.

Structure of fluoride salts

Salts including fluoride are numerous and embrace myriad structures. Usually the fluoride anion is surrounded by 4 or six cations, as is common for other halides. Sodium fluoride and sodium chloride embrace the same structure. For substances consisting of more than one fluoride per cation, the structures often deviate from those of the chlorides, as highlighted by the primary fluoride mineral fluorite (CaF2) where the Ca2+ ions are surrounded by eight F − centers. In CaCl2, each Ca2+ ion is surrounded by 6 Cl − centers. The difluorides of the shift metals frequently embrace the rutile structure whereas the dichlorides have cadmium chloride structures.

Inorganic chemistry

Upon treatment with a basic acid, fluoride salts transform to hydrogen fluoride and metal salts. With strong acids, it can be doubly protonated to offer H2F+

. Oxidation of fluoride provides fluorine. Solutions of inorganic fluorides in water consist of F − and bifluoride HF − 2. Couple of inorganic fluorides are soluble in water without undergoing considerable hydrolysis. In terms of its reactivity, fluoride differs substantially from chloride and other halides, and is more highly solvated in protic solvents due to its smaller radius/charge ratio. Its closest chemical relative is hydroxide, given that both have comparable geometries.

Naked fluoride

A lot of fluoride salts liquify to give the bifluoride (HF − 2) anion. Sources of real F − anions are unusual because the extremely standard fluoride anion abstracts protons from lots of, even adventitious, sources.

Relative unsolvated fluoride, which does exist in aprotic solvents, is called „naked“. Naked fluoride is a strong Lewis base, and an effective nucleophile. Some quaternary ammonium salts of naked fluoride include tetramethylammonium fluoride and tetrabutylammonium fluoride. Cobaltocenium fluoride is another example. However, they all lack structural characterization in aprotic solvents. Because of their high basicity, many so-called naked fluoride sources are in fact bifluoride salts. In late 2016 imidazolium fluoride was manufactured that is the closest approximation of a thermodynamically steady and structurally characterized example of a „naked“ fluoride source in an aprotic solvent (acetonitrile). The sterically requiring imidazolium cation stabilizes the discrete anions and secures them from polymerization.


At physiological pHs, hydrogen fluoride is generally totally ionised to fluoride. In biochemistry, fluoride and hydrogen fluoride are equivalent. Fluorine, in the form of fluoride, is thought about to be a micronutrient for human health, needed to prevent dental cavities, and to promote healthy bone development. The tea plant (Camellia sinensis L.) is a known accumulator of fluorine substances, launched upon forming infusions such as the typical beverage. The fluorine substances disintegrate into items including fluoride ions. Fluoride is the most bioavailable form of fluorine, and as such, tea is potentially a car for fluoride dosing. Roughly, 50% of absorbed fluoride is excreted renally with a twenty-four-hour period. The rest can be retained in the oral cavity, and lower gastrointestinal system. Fasting considerably increases the rate of fluoride absorption to near 100%, from a 60% to 80% when taken with food. Per a 2013 research study, it was discovered that usage of one litre of tea a day, can potentially provide the everyday advised consumption of 4 mg daily. Some lower quality brand names can provide up to a 120% of this amount. Fasting can increase this to 150%. The study shows that tea drinking communities are at an increased threat of dental and skeletal fluorosis, in the case where water fluoridation is in effect. Fluoride ion in low doses in the mouth minimizes dental caries. For this reason, it is utilized in tooth paste and water fluoridation. At much greater doses and regular direct exposure, fluoride triggers health issues and can be harmful. [4]

What are the functions of fluoride?

Among the main functions of fluoride is to keep the health of our bones and teeth.

Fluoride plays a key role in forming our teeth, by helping to enhance our tooth enamel during their growth and development. It also secures them from dental caries (tooth decay), by acting in the saliva and creating a layer over our teeth to decrease the damage brought on by acids from foods or those produced by oral germs.

Fluoride also assists to improve the density and solidity of bones, making them more steady. [5]

5 foods which contain fluoride

If you ask your dentist, they’ll have a lot to say about fluoride! That’s since fluoride offers lots of benefits for your oral health. Did you know that fluoride is a naturally happening mineral so many foods are a source of fluoride? Keep reading for 5 foods which contain fluoride so you can meet your fluoride needs from natural sources, too.

Grapes, raisins, and wine

Grapes are an excellent natural source of fluoride, which explains why raisins contain one of the highest concentrations of any food. It’s also one of the most flexible foods that contain fluoride. You can eat grapes fresh from the vine, sprinkle raisins on your morning oatmeal, or take pleasure in an aromatic glass of red wine or grape juice. Simply make sure to keep an eye out for sugarcoated in raisins or juice.


The kinds of fruit which contain fluoride are greatly diverse and seemingly limitless. Apples, strawberries, bananas, peaches, watermelon, and cherries are all on the list. It’s best to consume fruit fresh to enjoy the maximum benefits of the minerals and other nutrients they offer.


Lots of veggies are also a fantastic source of natural fluoride. Spinach and potatoes top the list. Like grapes, potatoes are likewise incredibly versatile with so many methods to cut, peel, cook, and enjoy them.


Shrimp, crab legs, and other seafood not only make for a fancy dinner or appetiser on unique celebrations, however they are likewise a very good source of fluoride.

Tea and coffee

Black tea and coffee are both natural sources of fluoride. For an included increase, if your city adds fluoride to the water supply, attempt developing with tap water for double the fluoride!

The right amount of fluoride

If you’re wanting to include additional fluoride to your regimen, it can be valuable to talk with your dental professional about dental products and foods which contain fluoride to assist guarantee that you get the correct amount. Fluoride uses numerous advantages for your dental health and your dental practitioner will more than happy to assist you find methods to add it to your diet and regular so that you get the maximum take advantage of this fantastic mineral. [6]

System of action

The avoidance of dental caries by topical fluoride is achieved by various mechanisms. Sodium fluoride eliminates germs that cause caries, such a Streptococcus mutans and lactobacilli by hindering their metabolic activities that lead to the formation of lactic acid. Fluoride ions trigger the inhibition of glycolytic and other enzymes associated with bacterial metabolism. It changes the permeability of cell membranes, reducing the pH in the cytoplasm of the cell, resulting in a reduction in level of acidity, which is typically implicated in dental caries.

When administered at low topical dosages, fluoride in both saliva and plaque and saliva prevent the demineralization of healthy tooth enamel while remineralizing teeth that have formerly been demineralized. Sodium fluoride is absorbed by the surface of hydroxyapatite crystals on the teeth, which are required for mineralization. This renders the teeth more resistant to demineralization by altering the apatite crystal solubility. Sodium fluoride hinders the demineralization of teeth in a pH-related way. When used in high doses, in solutions such as the fluoride varnishes or gels, sodium fluoride forms a layer on the surface of tooth enamel. When the pH of the mouth is reduced due to acid production by germs such as S.mutans, fluoride is released, disrupting bacterial metabolism, and after that acts to remineralize the teeth. [7]

What is fluoride utilized for?

In the context of human health, fluoride is mainly used to enhance oral health. You can sometimes find it in your regional water supply and in numerous over-the-counter (OTC) items, including:.

  • toothpaste
  • mouth rinses
  • supplements

If you tend to get a great deal of cavities, your dental professional might recommend using a prescription mouth wash with fluoride. These rinses generally have a higher concentration of fluoride than OTC choices do.

Fluoride is also utilized:.

  • in medical imaging scans, such as family pet scans
  • as a cleaner
  • in pesticides
  • to make Teflon, steel, and aluminum products [8]

Health Advantages

All across the United States, fluoride is added to public supplies of drinking water as a public health step to reduce cavities, also called dental caries. Choices about adding fluoride to public drinking water are made at the regional or state level.

Fluoride supplementation has been found to prevent the process of tooth decay in babies, children, and grownups. Fluoride exerts this advantageous result on teeth through direct contact, and it also safeguards establishing teeth that are still underneath the gums from the eventual development of cavities.

Fluoride is thought to assist prevent tooth decay in two methods: By preventing bacterial overgrowth and mineralizing the teeth.

Fluoride to the rescue

It’s mainly avoidable, but dental caries is the most typical persistent illness in both children and grownups in the United States. Still, the number of cases has decreased over the last 40 years, and many people credit the infusion of fluoride in public drinking water as one contributing element.

Preventing bacterial overgrowth

Fluoride has actually been revealed to minimize the overgrowth of specific bacteria that might contribute in triggering dental caries. Fluoride decreases the pH level in the mouth, making the oral environment more acidic and less hospitable to bacteria.

Fluoride has been discovered to prevent the growth of 3 types of oral germs: Streptococcus mutans, Streptococcus sanguinis, and Porphyromonas gingivalis.

Mineralization of teeth

Fluoride engages with the teeth to form a product called fluorapatite, which mineralizes the teeth. Mineralization is a process of chemical hardening, an effect that avoids tooth demineralization (breakdown). Interestingly, while fluorapatite is not a natural part of teeth, it is helpful and has actually not been discovered to trigger any harm to teeth.

The fluorapatite mineralization triggered by fluoride supplementation also assists the teeth withstand damage that can be brought on by food, beverages, and bacteria.

In regards to human health and nutrition, fluoride is a trace element, which comprises a fairly small portion of the body’s composition.

Little however Mighty

Fluoride is considered a micronutrient, indicating that it exists in bodily tissues only in little (or trace) quantities, or about 0.1% by volume. [9]

Fluoride deficiency

Fluoride shortage is a condition of the absence amount of fluoride in the body.


Fluoride is a microelement discovered in trace amounts in the organism. In the body, fluoride consists of the teeth and bones (95% of its total quantity) in the form of calcium fluoride. Fluoride includes into the teeth and kinds and hardens the tooth‘ enamels, produces the acid resistance and resistance to bacteria of the dental cavity. Some scientists recommend that fluoride avoids osteoporosis in females in the postmenopausal duration.

Fluoride is the most bioavailable form of fluorine, this form of fluorine is seen in the tea, which makes it essential as a source or fluoride. About fifty percent of fluoride is excreted by the kidneys within 24 hr after the absorption.

Causes and danger elements

Fluoride deficiency might be triggered by the insufficient amount of the fluoride in the diet. However, intake of fluoride in higher amounts may be poisonous and lead skeletal fluorosis (consumption of 20-80 mg/day).


Fluoride deficiency triggers the following signs:.

  • Terribly formed or weak teeth;
  • Dental caries (dental caries);
  • Teeth plaques;
  • Breakable or weak bones;
  • Predisposition to bone fractures;
  • Hip fractures in senior;


Sodium fluoride or sodium monofluorophosphate (fluoride-containing compounds) are administered topically and systemically to prevent the dental caries. These substances might be used to fluoridate water and in the production of oral health products. [10]


Excessive direct exposure to fluoride has actually been linked to a number of health concerns.

Oral fluorosis

A fluoride material of 0.7 ppm is now considered finest for oral health. A concentration that is above 4.0 ppm could be harmful.

Exposure to high concentrations of fluoride throughout youth, when teeth are developing, can lead to moderate oral fluorosis. There will be small white streaks or specks in the enamel of the tooth.

This does not affect the health of the teeth, but the discoloration might be noticeable.

Breastfeeding infants or making up formula milk with fluoride-free water can assist safeguard kids from fluorosis.

Kids below the age of 6 years ought to not use a mouthwash that contains fluoride. Children need to be monitored when brushing their teeth to guarantee they do not swallow tooth paste.

Skeletal fluorosis

Excess direct exposure to fluoride can result in a bone disease referred to as skeletal fluorosis. Over several years, this can result in discomfort and damage to bones and joints.

The bones may end up being solidified and less flexible, increasing the threat of fractures. If the bones thicken and bone tissue accumulates, this can add to impaired joint movement.

Thyroid issues

In many cases, excess fluoride can harm the parathyroid gland. This can lead to hyperparathyroidism, which includes uncontrolled secretion of parathyroid hormonal agents.

This can lead to a depletion of calcium in bone structures and higher-than-normal concentrations of calcium in the blood.

Lower calcium concentrations in bones make them more prone to fractures.

Neurological issues

In 2017, a report was published suggesting that exposure to fluoride before birth might lead to poorer cognitive results in the future.

The scientists determined fluoride levels in 299 ladies during pregnancy and in their children between the ages of 6 and 12 years. They evaluated cognitive ability at the ages of 4 years and in between 6 and 12 years. Greater levels of fluoride were associated with lower scores on IQ tests.

In 2014, fluoride was documented as a neurotoxin that could be harmful to child advancement, together with 10 other industrial chemicals, consisting of lead, arsenic, toluene, and methylmercury.

Other illness

According to the International Association of Oral Medication and Toxicology (IAOMT), an organization that campaigns against making use of included fluoride, it might also add to the following health problems:.

  • acne and other skin issues
  • cardiovascular issues, consisting of arteriosclerosis and arterial calcification, hypertension, myocardial damage, heart insufficiency, and heart failure
  • reproductive concerns, such as lower fertility and early puberty in ladies
  • thyroid dysfunction
  • conditions affecting the joints and bones, such as osteoarthritis, bone cancer, and temporomandibular joint condition (TMJ)
  • neurological problems, perhaps resulting in ADHD

One evaluation explains fluoride as an „extreme electron scavenger“ with an „insatiable appetite for calcium.“ The researchers require the balance of risks and benefits to be reconsidered.

Fluoride poisoning

Severe, high-level direct exposure to fluoride can cause:.

  • stomach pain
  • extreme saliva
  • queasiness and vomiting
  • seizures and muscle spasms

This will not arise from drinking faucet water. It is only most likely to happen in cases of unexpected contamination of drinking water, due, for example to an industrial fire or surge.

It is worth remembering that many substances are harmful in large amounts however valuable in percentages. [11]

Fluoride tooth paste

Brushing your teeth completely with fluoride toothpaste is one of the most effective methods of avoiding tooth decay.

A variety of toothpastes are available consisting of different levels of fluoride. The quantity of fluoride in the toothpaste can be discovered on the side of television and is measured in parts per million (ppm).

Toothpastes consisting of 1,350 to 1,500 ppm fluoride are the most efficient. Your dental expert may advise you to utilize higher-strength tooth paste if you or your kid is at specific risk of tooth decay.

  • Kids under 3 years of ages must brush twice daily, with a smear of tooth paste containing at least 1,000 ppm fluoride.
  • Children in between 3 and 6 years old ought to brush at least twice daily with a pea-sized amount of toothpaste including more than 1,000 ppm fluoride.
  • Adults should brush at least two times daily with a toothpaste consisting of 1,350-1,500 ppm fluoride.

Do not use mouthwash at the same time as brushing. Use it at an alternative time, because it removes the fluoride in the toothpaste [12]

Fluoride dose information

  • Mg of fluoride (mg f) each day (2.2 mg tablet of sodium fluoride consists of 1 mg of fluoride)
  • Fluoride supplements are commercially available in the form of drops or tablets. A sample prescription may read:
  • Sodium fluoride tablets 2.2 mg
  • One tablet each day to be chewed and swished before swallowing
  • Care: store out of reach of children
  • Supplements provide a topical along with systemic effect. The tablets ought to be thoroughly chewed and swished between the teeth before swallowing. The child should not eat or consume for 30 minutes after supplement ingestion
  • Fluoride levels in human breast milk are less than 0.05 ppm no matter drinking water and maternal plasma levels. The practitioner may want to consider recommending fluoride supplementation in solely breast fed infants in optimally fluoridated locations [13]

What other drugs will impact fluoride?

Some medications can make fluoride much less efficient when taken at the same time. If you take any of the following medicines, take your fluoride dose 1 hour prior to you take the other medicine:.

  • An antacid;
  • A laxative; or
  • A multivitamin or mineral supplement that contains calcium, aluminum, or magnesium.

Other drugs may affect fluoride, including prescription and over the counter medications, vitamins, and herbal products. Tell your doctor about all your present medications and any medication you start or stop utilizing. [14]

What are warnings and precautions for fluoride?


  • Greater dosages are unsafe and can weaken bones and ligaments, and cause muscle weakness and nerve system issues. High doses of fluoride in children prior to their irreversible teeth come through the gums can cause tooth staining
  • Toothpaste and fluoride rinses must not be swallowed regularly, particularly in kids. It’s a good concept to make sure that children under 6 years of age use only a pea-sized quantity of fluoride-containing tooth paste, simply in case they swallow some
  • This medication consists of fluoride. Do not take luride, karidium, fluoritab, pediaflor, or sodium fluoride if you dislike fluoride or any active ingredients included in this drug
  • Keep out of reach of kids. In case of overdose, get medical help or get in touch with a toxin control center immediately


Hypersensitivity to fluoride, tartrazine, parts of the formulation.

Fluoride content in driving water greater than 0.7 ppm.

Low sodium or sodium-free diet plans.

1 mg tablet in kids under 3 years of age or when consuming water has more than 0.3 ppm.

1 mg/5 ml rinse in kids under 6 years of age.


Greater dosages are hazardous and can damage bones and ligaments, and trigger muscle weak point and nerve system problems. High dosages of fluoride in kids prior to their irreversible teeth come through the gums can cause tooth staining.

Tooth paste and fluoride rinses need to not be swallowed routinely, particularly in children. It’s an excellent idea to make certain that kids under 6 years of age usage just a pea-sized quantity of fluoride-containing toothpaste, simply in case they swallow some.

Pregnancy and lactation

Fluoride may be acceptable for usage during pregnancy. Either animal research studies show no threat but human studies are not readily available or animal studies revealed minor risks and human studies were done and showed no threat.

Fluoride is safe throughout breastfeeding when used in doses below 10 mg each day or essential fluoride; it is safe in quantities discovered in tooth pastes, mouth rinses, and fluoride oral treatments. [15]


All organisms are exposed to fluoride from natural and/or anthropogenic sources. Extremely high consumptions have actually been observed in areas worldwide in which the environment is abundant in fluoride and where groundwater high in fluoride is consumed by human beings. Increased direct exposure might take place in the vicinity of point sources. Fluoride in dental products is an additional source for many individuals.

Fluoride has both helpful and detrimental impacts on human health, with a narrow variety in between the consumption at which these take place.

Results on the teeth and skeleton might be observed at direct exposures below those associated with the advancement of other organ- or tissue-specific negative health effects.

Effects on the bone (e.g., skeletal fluorosis and fracture) are considered the most relevant results in evaluating the adverse effects of long-lasting exposure of people to fluoride.

Skeletal fluorosis is a crippling impairment that has a significant public health and socioeconomic effect, affecting millions of individuals in numerous areas of africa, china and india.

Consumption of fluoride in water and foods is the primary causative aspect for endemic skeletal fluorosis. In some regions, the indoor burning of fluoride-rich coal also serves as an important source of fluoride. [16]
