See a dentist: Bleeding in your mouth can be a sign that you already have, gum disease. The bacteria and other particles, constantly form a sticky, colorless toxic “plaque” on teeth causing the gums to become inflamed and to easily bleed. This is a serious problem, which should be checked professionally by a dentist. The good news is that this condition is curable. Call your dentist today!

Blood in mouth: Blood in your mouth could have come from a number of different sources, including your gums, your nose, your lungs, and your stomach. Even biting your cheek or tongue accidentally while sleeping will cause bleeding. Is this a one time event or does it happen often? You should be examined by a physician and dentist to rule out all causes.

Dentist: See your Dentist. May be from gum infection (Periodontal Disease) which is progressive and destructive. Your Dentist may want to refer you onto a gum specialist, a Periodontist, if you have gum disease. If not, your Dentist will refer you to your General Physician or medical specialist for evaluation.
