Fluoride

 

How can fluoride prevent tooth decay?

Fluoride fulfills two important dental functions.  First, it helps to 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 pediatric dentist biannually, all supplement the work of fluoride and keep young teeth healthy.

How much fluoride is enough?

Since community water supplies and toothpastes usually contain fluoride, it is essential that children do not ingest too much.  For this reason, children under the age of two should use a smear or rice sized-amount of ADA-approved fluoridated brand of toothpaste.  Children between the ages of three and six years old should use a pea-sized amount of ADA-approved fluoridated toothpaste on a clean toothbrush twice each day.  They should be encouraged to spit out any extra fluid after brushing.  This part might take time, encouragement, and practice.
