In the last half century, fluoride has become an effective weapon against tooth decay. The naturally occurring mineral helps strengthen enamel, the teeth's hard, protective cover.
Although it's safe for consumption overall, too much during early tooth development can lead to fluorosis, a brownish, mottled staining in enamel. To avoid it, a child's daily consumption of fluoride should optimally be kept at around 0.05-0.07 milligrams per kilogram of body weight, or an amount equal to one-tenth of a grain of salt per two pounds of weight.
The two main therapeutic fluoride sources have limits to help maintain this balance: utilities that fluoridate drinking water are required to add no more than 4 parts fluoride per million (ppm) of water; toothpaste manufacturers likewise only add a small amount of fluoride compared to clinical gels and pastes dentists apply to teeth for added decay protection.
But drinking water and toothpaste aren't the only sources of fluoride your child may encounter. Even if you have a non-fluoridated water supply, you should still keep a close watch on the following items that could contain fluoride, and discuss with us if you should take any action in regard to them.
Infant formula. The powdered form especially if mixed with fluoridated water can result in fluoride concentrations 100 to 200 times higher than breast or cow's milk. If there's a concern, use fluoride-free distilled or bottled spring water to mix formula.
Beverages. Many manufacturers use fluoridated water preparing a number of packaged beverages including sodas (two-thirds of those manufactured exceed .6 ppm), soft drinks and reconstituted fruit juices. You may need to limit your family's consumption of these kinds of beverages.
Certain foods. Processed foods like cereals, soups or containing fish or mechanically separated chicken can have high fluoride concentrations, especially if fluoridated water was used in their processing. When combined with other fluoride sources, their consumption could put children at higher risk for fluorosis.
Toothpaste. Although mentioned previously as a moderate fluoride source, you should still pay attention to how much your child uses. It doesn't take much: in fact, a full brush of toothpaste is too much, even for an adult. For an infant, you only need a smear on the end of the brush; as they grow older you can increase it but to no more than a pea-sized amount.

Since the discovery a century ago of its beneficial effect on tooth enamel, fluoride has become an important part of tooth decay prevention. It's routinely added to toothpaste and other hygiene products, and many water utilities add minute amounts of it to their drinking water supplies. Although there have been questions about its safety, multiple studies over the last few decades have eased those concerns.
Children especially benefit from fluoride during their teeth's developing years. Some children are at high risk for decay, especially an aggressive form known as Early Childhood Caries (ECC). ECC can destroy primary (baby) teeth and cause children to lose them prematurely. This can have an adverse effect on incoming permanent teeth, causing them to erupt in the wrong positions creating a bad bite (malocclusion).
For children at high risk for decay, dentists often recommend applying topical fluoride directly to the teeth as added protection against disease. These concentrations of fluoride are much higher than in toothpaste and remain on the teeth for much longer. Topical applications have been shown not only to reduce the risk of new cavities, but to also stop and reverse early decay.
Children usually receive these applications during an office visit after their regular dental cleaning. There are three different ways to apply it: gel, foam or varnish. To prevent swallowing some of the solution (which could induce vomiting, headache or stomach pain) the dentist will often insert a tray similar to a mouth guard to catch any excess solution. Varnishes and a few gels are actually painted on the teeth.
The American Dental Association has intensely studied the use of topical fluoride and found its application can result in substantial decreases in cavities and lost teeth. They've concluded this benefit far outweighs the side effects from ingesting the solution in children six years and older. With proper precautions and waiting to eat for thirty minutes after an application, the possibility of ingestion can be reduced even further.
While topical fluoride can be effective, it's only one part of a good dental care strategy for your child. Consistent daily brushing and flossing, a nutritious diet low in added sugar, and regular dental visits still remain the backbone of preventive care.
Like many other families, you may use formula instead of breast milk as a safe and healthy alternative to feed your infant. But, if you use a powdered form that you mix with water your child may be taking in more fluoride than they require.
Fluoride is a natural chemical that can strengthen tooth enamel and help prevent decay. After decades of study it's also been shown to pose no serious health risks. Because of fluoride's benefits and safety, many water utilities add tiny amounts to their drinking water supply.
But it can have one side effect called enamel fluorosis. If a child ingests too much fluoride during early development it can cause discoloring mottled spots or streaking in permanent teeth. Although it doesn't affect their health, the teeth can be unattractive and require cosmetic attention.
That's why it's best to keep fluoride consumption to a healthy minimum for children. That, however, is often easier said than done, since we can encounter hidden fluoride in a variety of places. Besides hygiene products and fluoridated drinking water, you may find fluoride in prepared juices and other beverages, bottled water or in foods processed with fluoridated water. There are no labeling requirements for fluoride, so you'll have to research to find out if a product contains fluoride.
There are, however, some things you can do to control your child's fluoride intake. First, know as much as you can about known sources your child may encounter like your water supply. You can find out if your utility adds fluoride and by how much by contacting them or visiting My Water's Fluoride online at https://nccd.cdc.gov/DOH_MWF/.
If you use fluoride toothpaste apply only a “smear” on the end of the brush for children under two and a pea-sized amount for older children. If you have fluoridated drinking water, consider breastfeeding your infant, use ready-to-feed formula or mix powdered formula with bottled water labeled “de-ionized,” “purified,” “demineralized” or “distilled.”
And, do feel free to discuss your concerns with us during your child's regular checkup. We'll help you adjust their diet, water intake and hygiene habits to be sure they're receiving the right amount they need for developing strong teeth — and no more.

Protecting a child's primary (“baby”) teeth from tooth decay should be a top priority. If one is lost prematurely due to decay, it could cause the permanent tooth to misalign when it comes in.
The basic prevention strategy for every child is daily brushing and flossing and regular dental visits. But children at higher risk for decay may need more: Â additional fluoride applied to teeth enamel during office visits.
This natural mineral has been shown to strengthen enamel, teeth's protective layer against decay, especially during its early development. Enamel is composed of calcium and phosphate minerals interwoven to form a crystalline structure called hydroxyapatite. Fluoride joins with this structure and changes it to fluorapatite, which is more resistant to mouth acid than the original structure.
We mostly receive fluoride through fluoridated drinking water and dental care products like toothpaste. Topical fluoride takes it a step further with a stronger dose than found in either of these sources. It can be applied with a foam, varnish or gel using an isolation tray (foam or gel) or painted onto the enamel (varnish or gel).
But does topical fluoride effectively reduce the occurrence of decay? Research indicates yes: a recent review of 28 studies involving over 9,000 children found an average 28% reduction in decayed teeth in children who underwent topical fluoride treatments.
There is, though, one potential side effect: children who swallow the fluoride substance can become sick and experience headache, stomach pain or vomiting. This can be avoided with proper precautions when applying it; the American Dental Association also recommends using only varnish for children younger than 6 years. It's also recommended that children receiving gel or foam not eat or drink at least thirty minutes after the treatment (those who receive the varnish aren't restricted in this way).
Topical fluoride is most effective as part of an overall prevention strategy. Besides daily hygiene and regular dental visits, you can also help reduce your child's decay risk by limiting the amount of sugar in their diet. Sealants, which are applied to the nooks and grooves of teeth where plaque can build up, may also help.
Fluoride has been proven to strengthen tooth enamel against decay. That’s why it’s not only added to toothpaste and other dental products, but also to drinking water — in nearly three-quarters of U.S. water systems.
While research has eased most serious health questions about fluoride, there remains one moderate concern. Too much fluoride over time, especially in infants and young children, could lead to “enamel fluorosis,” an excess of fluoride in the tooth structure that can cause spotting or streaking in the enamel. While often barely noticeable, some cases of fluorosis can produce dark staining and a pitted appearance. Although not a symptom of disease, fluorosis can create a long-term cosmetic concern for the person.
To minimize its occurrence, children under the age of 9 shouldn’t regularly ingest fluoride above of the recommended level of 0.70 ppm (parts per million). In practical terms, you as a parent should monitor two primary sources of fluoride intake: toothpaste and drinking water.
Young children tend to swallow toothpaste rather than spit it out after brushing, which could result in too much fluoride ingestion if the amount is too great. The American Academy of Pediatric Dentistry therefore recommends a small “smear” of toothpaste for children under two, and a pea-sized amount for children up to age six. Brushing should also be limited to no more than two times a day.
Your child or infant could also take in too much fluoride through fluoridated drinking water, especially if you’re using it to mix infant formula. You should first find out the fluoride levels in your local water system by contacting the utility or the health department. If your system is part of the U.S. Centers for Disease Control and Prevention’s (CDC) “My Water’s Fluoride” program, you may be able to access that information on line at http://apps.nccd.cdc.gov/MWF/Index.asp.
If the risk for developing fluorosis in your area is high, you can minimize your infant’s intake with a few recommendations: breastfeed rather than use formula; use “ready-to-feed” formula that doesn’t need mixing and contains lower fluoride levels; and use bottled water specifically labeled “de-ionized,” “purified,” “de-mineralized,” or “distilled.”
Fluoride can be a wonderful adjunct to dental care in reducing risk for tooth decay. Keeping an eye on how much fluoride your child takes in can also minimize the chance of future appearance problems.
