Fluoride is a highly effective part of your tooth decay prevention program, no matter what your age. When children are young and their teeth are forming, fluoride joins with the enamel surface and makes it harder and more resistant to decay. For adults, fluoride can repair an early cavity – even before it’s become visible in the mouth – by rebuilding the enamel layer of the teeth. And in older adults, fluoride can help to solve the problem of root decay or root sensitivity.
It is certainly important for infants and children between the ages of 6 months and 16 years to be exposed to fluoride. This is the timeframe during which the primary and permanent teeth come in. However, adults benefit from fluoride, too. New research indicates that topical fluoride – from toothpastes, mouth rinses, and fluoride treatments – are as important in fighting tooth decay as in strengthening developing teeth.
In addition, people with certain conditions may be at increased risk of tooth decay and would therefore benefit from additional fluoride treatment.
