When it comes to helping your child avoid tooth decay, it's all hands on deck. Tooth decay can not only harm their current set of primary teeth, but the loss of even one tooth could lead to bite problems later on.
And, even if you're doing all the right things—daily brushing and flossing, limiting sugar consumption and regular dental visits—your child might still develop cavities. If so, it may be necessary to add a boost of prevention with topical fluoride applied by your dentist.
With its enamel-strengthening properties, fluoride plays an important role in dental disease prevention. For decades, manufacturers have added fluoride to toothpaste. And, many water utilities now add tiny amounts of fluoride to their drinking supply.
According to a number of studies, these fluoride applications are effective weapons against tooth decay. But direct applications of fluoride to tooth surfaces can provide even greater benefit to children with a higher susceptibility for decay.
Topical fluoride is usually applied by means of a gel, foam or varnish. In varnish form, it's brushed on the teeth, while dentists apply the foam solution within a tray fitted around the teeth. The gel application can be administered by either method.
Although these topical applications use a higher concentration of fluoride than you find in toothpaste, it poses no serious danger to a child's health. But because high doses of fluoride can lead to staining, topical applications are only administered periodically during childhood.
The only short-term health concern is if the child accidentally swallows some of the mixture during application. This can cause symptoms like an upset stomach, vomiting or headache. Dentists, however, take a number of precautions to prevent accidental ingestion in order to avoid these unpleasant side effects.
The benefits, though, appear to well outweigh this minor risk. In a review of several scientific studies involving nearly 10,000 children, there was an average 28% reduction in decayed, missing or filled teeth in those children that underwent topical fluoride treatments.
If you want to know more about topical fluoride treatments and whether they can help your child avoid tooth decay, talk to your dentist. This fluoride booster could help further protect them from this destructive dental disease.

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.
For over half a century now, community water systems have been adding fluoride to drinking water to help reduce the risk of tooth decay. Numerous long-term studies have demonstrated the soundness of this practice, prompting the U.S. Centers for Disease Control to call water fluoridation one of the ten most effective public health measures of the 20th Century.
In the 1960s, after years of study into the teeth-strengthening effects of fluoride, the U.S. Public Health Service recommended that drinking water utilities add fluoride at a rate of between 0.7 and 1.20 milligrams per liter (mg/L) or parts per million (ppm) of water. This recommendation held fast until 2015 when the service changed the recommendation to no more than 0.7 mg/L.
Why the change to guidelines that had been in place for over fifty years? The revision was in response to an increasing occurrence of dental fluorosis. This condition happens when the teeth absorb more fluoride than necessary, leading to discoloration of the surface enamel, creating effects like small white spots or brownish “mottling.”
Dental fluorosis is the only known health condition caused by fluoride. As such, it doesn't damage the tooth itself, and is mainly a cosmetic problem. But it can still be avoided if fluoride intake is kept at moderate levels.
The original recommendation was sound science when first introduced. Since then, though, the prevalence of fluoride in everyday life has grown, with the chemical commonly found in dental care products like toothpastes or mouthrinses, as well as many processed foods and beverages and even infant formula. Our society's overall intake of fluoride has been growing as a result.
The new recommendation came after several years of research to verify water fluoridation levels of 0.7 mg/L would still be effective in the fight against tooth decay while lowering the risk of dental fluorosis. With this adjustment, this important and safe measure for keeping your family's teeth protected against disease is safer than ever.
Fluoride is an important part of your child's dental development. But if children take in too much of this important mineral, they could experience enamel fluorosis, a condition in which teeth become discolored with dark streaking or mottling.
That's why it's important to keep fluoride levels within safe bounds, especially for children under the age of 9. To do that, here's a look at the most common sources for fluoride your child may take in and how you can moderate them.
Toothpaste. Fluoridated toothpaste is an effective way for your child to receive the benefits of fluoride. But to make sure they're not getting too much, apply only a smear of toothpaste to the brush for infants. When they get a little older you can increase that to a pea-sized amount on the end of the brush. You should also train your child not to swallow toothpaste.
Drinking water. Most water systems add tiny amounts of fluoride to drinking water. To find out how much your water provider adds visit “My Water's Fluoride” (//nccd.cdc.gov/doh_mwf/Default/Default.aspx) online. If it's more than the government's recommendation of 0.70 parts of fluoride per million parts of water, you may want ask your dentist if you should limit your child's consumption of fluoridated drinking water.
Infant formula. Many parents choose bottle-feeding their baby with infant formula rather than breastfeed. If you use the powdered form and mix it with tap water that's fluoridated, your baby could be ingesting more of the mineral. If breastfeeding isn't an option, try using the premixed formula, which normally contains lower levels of fluoride. If you use powdered formula, mix it with bottled water labeled “de-ionized,” “purified,” “demineralized” or “distilled.”
It might seem like the better strategy for preventing fluorosis is to avoid fluoride altogether. But that can increase the risk of tooth decay, a far more destructive outcome for your child's teeth than the appearance problems caused by fluorosis. The better way is to consult with your dentist on keeping your child's intake within recognized limits to safely receive fluoride's benefits of stronger, healthier teeth.

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.
