Your family uses fluoride toothpaste and your drinking water is fluoridated too. So with the fluoride your child already takes in, is it really necessary for topical fluoride treatments during their regular dental visits?
The answer is most definitely. Fluoride has a unique ability to strengthen enamel, your teeth’s protective cover against decay and other diseases. It does this by infusing itself in the enamel structure and making it that much more resistant to acid attack and decay.
This infusion occurs in two ways. First, growing teeth obtain it through the bloodstream as they incorporate other minerals that make up the enamel structure. The very small amount of fluoride added to drinking water — as low as one part per million (ppm) — imparts sufficient fluoride to developing teeth. In the absence of fluoridated water, dietary fluoride supplements can achieve the same effect.
The second way is just after the teeth have erupted and are still quite young. In this case, fluoride coming in direct contact with the enamel surface is absorbed, resulting in changes to the enamel’s crystalline structure that will create added strength. This can occur to a limited degree through fluoride toothpaste or other dental products. The concentration of fluoride in these products, though, is relatively low (850-1500 ppm) as mandated by the U.S. Food and Drug Administration for safety.
Professional applications, on the other hand, are much higher — 12,300 to 22,600 ppm depending on their form. They’re applied, of course, under strict clinical guidelines to cleaned tooth surfaces, usually as a gel, foam or varnish. The latter form will often continue leaching fluoride into the enamel for a month or more.
These topical applications can greatly strengthen the teeth of children who don’t have the benefit of fluoridated water or may be at higher risk for dental disease because of socio-economic conditions. But they can still be helpful for children with adequate fluoride exposure and low risk factors for disease. At the very least, fluoride treatments can give your child an added boost of protection as their teeth continue to develop.

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.
We've known for a long time that fluoride strengthens tooth enamel against decay. We've also learned that fluoride consumption early in life pays later dividends with healthier teeth.
But while fluoride has generally proven safe, too much ingested by young children could cause enamel fluorosis. This condition produces a mottled or streaked appearance in teeth ranging from faint white patches to darker, pitted staining. Fluorosis doesn't harm teeth, but it does make them less attractive.
To prevent this, it may be necessary with your dentist's help to monitor your infant's or young child's fluoride intake and keep it in check. That will depend in large part on where you live, as well as your child's hygiene and eating habits.
Like three-quarters of public water systems, your local utility may be adding fluoride to your drinking water. The amount is governed by federal guidelines, which currently recommend fluoride amounts of no more than 0.70 parts per million of water. The fluoride levels in your water could have an impact on your child's total fluoride intake. You can find out for sure how much fluoride is present in your water by contacting your water utility company.
Another major fluoride source is toothpaste and other hygiene products. You can control your child's fluoride exposure by limiting the amount of toothpaste on their brush. Children under two only need a “smear,” while those between two and six need only a pea-sized amount.
Processed foods can contain fluoride if fluoridated water was used in their production. In this case, replace as much of the processed food items in your family's diet as you can with fresh fruits, vegetables and other foods.
Along this line, if you have an infant you want to pay particular attention to feeding formula, especially the powdered form you mix with water. If you're concerned about the amount of fluoride in your water consider other infant feeding options. Besides breast-feeding in lieu of formula, you can also use ready-to-feed pre-mixed with water (usually lower in fluoride) or mix powdered formula with bottled water specifically labeled “de-ionized,” “purified,”Â “demineralized,” or “distilled.”
This can be a lot to keep up with but your dentist can advise you. Fluoride is still a potent weapon against tooth decay and a safeguard on your child's current and future dental health.

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.

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.
