Fluoride

Fluorine, a natural element in the fluoride compound, has proven to be effective in minimizing childhood cavities and tooth decay.  Fluoride is a key ingredient in many popular brands of toothpaste, oral gel, and mouthwash, and can also be found in most community water supplies.  Though fluoride is an important part of any good oral care routine, overconsumption can result in a condition known as fluorosis.  

How can fluoride prevent tooth decay?

Fluoride fulfills two important dental functions.  First, it helps staunch mineral loss from tooth enamel, and second, it promotes the remineralization of tooth enamel.

When carbohydrates (sugars) are consumed, oral bacteria feed on them and produce harmful acids.  These acids attack tooth enamel - especially in children who take medications or produce less saliva.  Repeated acid attacks result in cavities, tooth decay, and childhood periodontal disease.  Fluoride protects tooth enamel from acid attacks and reduces the risk of childhood tooth decay.

Fluoride is especially effective when used as part of a good oral hygiene regimen.  Reducing the consumption of sugary foods, brushing and flossing regularly, and visiting the dentist biannually, all supplement the work of fluoride and keep young teeth healthy.

How much fluoride is enough?

Although most community water supplies contain fluoride, many people are drinking and using bottled water which does not contain fluoride. If your child is not drinking fluoridated water, you may want to use a fluoride supplement. Prior to being able to spit, children needing fluoride supplementation should either take multivitamins with fluoride or fluoride tabs. Once they can spit, fluoridated toothpastes and rinses can be utilized. 

Does my child need fluoride supplements?

The dental team is the best person to decide whether a child needs fluoride supplements.  First, the dentist will ask questions in order to determine how much fluoride the child is currently receiving, gain a general health history, and evaluate the sugar content in the child’s diet.  If a child is not receiving enough fluoride and is determined to be at high-risk for tooth decay, an at-home fluoride supplement might be recommended.

Topical fluoride can also be applied to the tooth enamel quickly and painlessly during a regular office visit.  There are many convenient forms of topical fluoride, including foam, liquids, varnishes, and gels.  Depending on the age of the child and their willingness to cooperate, topical fluoride can either be held on the teeth for several minutes in specialized trays or painted on with a brush.
