Bite dysfunction is a lack of 'harmony' or balance between the jaw joints and teeth.  Whether young or old, lack of balance between these structures can occur.  Symptoms may range from tooth wear, receding gum tissues to excessive bone loss and chronic joint and muscle pain, all of which become more obvious as we age.
 

Some of the symptoms of bite dysfunction are:

Grinding at Night

Head/Neck/Shoulder aches

Receding gum tissue and wear on teeth

A history of ongoing dentistry including repeat root canals and crowns

Chronic joint and muscle pain
