I am worried about my mouth. I feel I may have gum disease (blood when brushing, although that only occured when I got a new tooth brush) but my gums have bled for as long as I can remember. I am worried about periodontitis , because I woke up one morning and there some blood in mouth but that was only once. Also I can feel like a sore pain on one of those little horns under your tongue as well as one on the side of the tongue. I also feel the roof of my mouth may be swollen (again I have had this before). Am I overreacting here?
