As an adult, do I still have to worry about cavities?
This common misconception is likely from when fluoride treatments were only for children. Adults and children of any age can develop decay. Furthermore, recent research has shown that fluoride varnish treatments help prevent and arrest decay in adults that are high risk too. Adults with old restorations, gum recession, or dry mouth are more likely to experience decay. As gums recede, the softer dentin of the root surface is significantly more susceptible to acid and decay. Saliva is also important for sweeping harmful acid and food from the mouth, so reduced salivary flow greatly increases risk for cavities.
