Keeping teeth clean may become more involved.  The formation of plaque, a colorless layer of bacteria that builds up on teeth, accelerates as we grow older.  Teeth also may darken in color due to changes in dentin, the bone-like tissue underneath tooth enamel. Gums may begin to recede from teeth.  This process exposes tooth roots to plaque and can cause tooth decay.  In addition, older fillings may weaken and crack, allowing bacteria to accumulate around the edges of fillings - causing cavities. Unfortunately, many individuals over the age of 50 have decay on both teeth and roots which may require clinical care. "Dry Mouth" may develop caused by a reduced saliva flow and may lead to tooth damage.  Reduced saliva flow may be a medical disorder or a side effect of medications such as antihistamines, decongestants, pain killers or diuretics.  The reduced flow affects teeth because saliva acts as a cleaning agent in the mouth to wash away acids produced by plaque.  When the mouth is not adequately lubricated and moistened by saliva, plaque forms more quickly and produces cavities. Gum disease develops more readily.   Bacteria found in sugars and starches create toxins which irritate the gums and cause gum tissue to separate from teeth.  Left untreated, gum disease can cause unnecessary tooth loss.  It also may dissolve the bone that holds your teeth in place.  Poorly fitted dentures, poor oral hygiene, illnesses and some medications may increase the severity of gum disease and create chewing problems and pain in the jaw.  Fortunately, visiting your dentist regularly can help reduce the spread of gum disease and its damaging effects.
