I'm bleeding from under my tongue is been bleeding for awhile is just a little and i notice it more when i brush my teeth. what could it be?

Bleeding: Bleeding is not normal and a sign of some problem. Most likely it's from periodontal (gum) disease although it could be a host of other things. You will need to see a dentist who can determine exactly what it is and what treatment is necessary.

Get it checked: You should go to the dentist to have it checked. You should not have bleeding in your mouth.
