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.

Fluoride is an important weapon in the fight against tooth decay. Fluoride consumption and other applications are especially beneficial during children's dental development for building strong teeth long-term.
But the truism "too much of a good thing" could aptly apply to fluoride. If a child consumes too much fluoride over an extended period of time, it could cause a condition called enamel fluorosis in which the enamel surface develops mottled or streaked staining. It's not harmful to the tooth's health, but it can greatly diminish a person's smile appearance.
To avoid fluorosis, it's important with the help of your dentist to know and regulate as much as possible the amount of fluoride your child receives. Here are 3 fluoride sources you should manage.
Toothpaste. Many manufacturers add fluoride to their toothpaste formula, usually an important way to receive this tooth-strengthening chemical. But younger children tend to swallow more toothpaste than older children or adults. Because the chemical builds up in the body over time, swallowing toothpaste every day could potentially elevate your child's fluoride levels. To avoid this, just use a "smear" of toothpaste on the brush for children under age 2, and a pea-sized amount for older children.
Your water system. About three-quarters of all public water utilities add fluoride to their water as an added measure for tooth decay prevention. The amount can vary from system to system, although the maximum amount recommended by the U.S. Government is 0.70 parts per million (PPM). You can ask your local water system how much fluoride, if any, is present or they add to your drinking water.
Bottled water. Any type of bottled beverage (water, juices, sodas, etc.) could contain various levels of fluoride. Unfortunately there are no labeling requirements regarding its presence, so the most prudent course is to carefully manage the beverages your child drinks, or stay with bottled water marked "de-ionized," "purified," "demineralized" or "distilled," which typically have lower fluoride levels. For babies feeding on milk, you can use the aforementioned bottled waters to mix powder, use ready-to-feed formula (also low in fluoride) or breast-feed.

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.

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.
