The topical application of fluoride has has been investigated since the early 1940's. Numerous clinical studies have evaluated the cavity protection offered by topical application of specific fluoride products. Most of the early caries (cavities) studies involved the permanent teeth of children. The clinical results in studies involving adults, however, are positive, and the same protective mechanism that are active in children also apply to adults.

A recent National Institute of Dental Research survey found that adults had an average of 23 decayed and filled tooth surfaces, with 30% of adults having more than 30 decayed or restored surfaces. Recurrent or secondary decay around fillings can represent major problems. Surveys demonstrate that 40-50% of replaced fillings were caused by recurrent cavities.

As we grow older, many of us suffer from gum recession. This means root surfaces become exposed, providing a new group of susceptible areas not generally found in children. In the U.S., adults are living longer and keeping a greater number of their teeth; therefore, the incidence of root cavities in the adult population is steadily increasing. On another related issue, tooth sensitivity (hot or cold sensitivity) now affects 1 in 7 adults which is approximately 40 million Americans at one time or another.

Fluoride treatments can be the answer for you. The latest research has demonstrated that properly applied fluoride not only inhibits cavities by forming a more acid-resistant surface layer, but it also works by reversing or remineralizing early forming cavities (white spots). It is now understood that fluoride is capable of enhancing the rate of natural remineralization by saliva. Fluoride relieves tooth sensitivity by initiating a rapid mineralization of the exposed root surfaces.

Your dental professional can best advise you whether fluoride treatments are indicated. The bottom line is that many adults can benefit from fluoride treatments!
