You're doing all the right things helping your child avoid tooth decay: daily brushing and flossing, regular dental visits and a low-sugar diet. But although occurrences are low, they're still getting cavities.
Some children still struggle with tooth decay even with proper dental care. If this is happening to your child, your dentist may be able to give them an extra preventive boost through topical fluoride.
Fluoride has long been recognized as a proven cavity fighter. Often added in small amounts to toothpastes and drinking water, fluoride strengthens tooth enamel against acid attacks that create cavities. With topical fluoride, a dentist applies a varnish, foam or gel containing a more concentrated amount of the chemical directly to the teeth.
The effectiveness of this method in reducing tooth decay is well-founded: A number of scientific studies involving thousands of children and adolescents found an average 28% reduction in occurrences of decay among those who received the treatment compared to those who didn't.
Still, many parents have concerns about the higher fluoride concentrations in topical applications. But even at this greater amount, fluoride doesn't appear to pose any long-term health risks. The most adverse effects—vomiting, headaches or stomach pain—usually occur if a child accidentally ingests too much of the solution during treatment.
Dentists, however, go to great lengths to prevent this by using guards to isolate the solution during an application. And in the case of a foam or gel application, parents can further lower the risk of these unpleasant side effects by not allowing their child to eat or drink for at least thirty minutes after the procedure.
The evidence seems to indicate that the benefits of regular topical fluoride applications for children at high risk outweigh the possible side effects. By adding this measure to your prevention strategy, you can further protect your child from this danger to their current and future dental health.

We've known for decades that fluoride strengthens tooth enamel and lowers the risk for decay. And while adding it to toothpaste and drinking water are the more common ways for getting it into the body, an increasingly popular way—especially for children—is to apply fluoride directly to the teeth.
But is topical fluoride really worth the effort and expense? And, are there any side effects to treating teeth this way?
As to the first question, researchers have performed numerous studies measuring fluoride's effectiveness for preventing tooth decay. The Cochrane Oral Health Research Group recently reviewed studies on topical fluoride applications involving nearly 10,000 children and adolescents between the ages of 2 and 15. The combined average for all the studies showed a 28% reduction in decayed teeth for patients who received topical fluoride compared to those who didn't.
This was especially true for children at high risk for decay: directly applying fluoride gels, foams or varnishes to teeth reduces that risk substantially. But there are also side effects to this application. Fluoride in general has only one known safety concern, a condition known as fluorosis. Too much fluoride over time can cause heavy discoloration of the teeth. This does not affect the health of the teeth, but it can look unattractive and require cosmetic treatment to reduce its effect.
There's little to no risk for fluorosis with the controlled treatments offered by dentists; the fluoride solution remains on the teeth no more than a few minutes. But there is a possible side effect during treatment due to the relatively high dose of fluoride used. If the patient accidentally swallows some of the solution, the concentration of fluoride can cause stomach upset, vomiting or headaches.
Dentists minimize the chances for this by usually using the more difficult to swallow varnish form of topical fluoride on younger patients, and using trays or other barrier devices to isolate the fluoride solution from the rest of the mouth. Under professional supervision, it's rare for an accidental ingestion to occur.
The risks for these side effects are quite low, and the benefits of topical fluoride for reducing the chances for decay can more than outweigh them. Fluoride applications are one of many ways we can protect your child's current and future dental health.
