tooth decay as we age

Recently a patient asked me why people seem to get tooth decay as they get older after years of being decay free.  The answer is that as we age we lose some gum tissue around our teeth and then areas of the root becomes exposed.  This part of the tooth is less resistant to bacteria and more likely to become decayed.  There are some easy ways to reduce the chances of getting decay.  Rinse with a fluoride containing mouth rinse and brush with a prescription strength tooth paste.  If your mouth is dry you also need to be sure to use artificial saliva to make sure your mouth stays moist.
