Patients see dentists on average twice as often as their primary care physician.

With this in mind, it makes it necessary that dentists are aware of the oral health signs of disease within the body.  Serious diseases such as anorexia and bulimia as well as diabetes generally show symptoms first within the oral cavity.  Anorexia and bulimia deprive people of key nutrients, which causes the gum tissue to lose its healthy pink color.  These eating disorders can also erode teeth because of the excessive stomach acid that they are in contact with.  Diabetes can manifest itself in a banana-like smell in  the mouth or constant bad breath.  It also causes excessive bleeding and a lessening to taste of foods.
