Symtoms Vs Health: If you have Pain(symtoms) one needs to see a dentist. Many dental problems can be detected well before a patient has symptoms. The remedial care you receive with early discovery(diagnosis) is ususally less complicated.

Now: Color change, either red or white, should be investigated immediately. Many oral problems are painless in their earliest stages (a small cavity is painless, an abscess is painful). Please call your Dentist NOW.
