Gum Problems or Wisdom Teeth.?

On the very back (were the back teeth are) bottum row. I have a wisdom tooth there but just behind it it looks like my gum is pelling off. Its normal color. And I brush 5 times a week butI dont have any cavities. Sometimes I floss. But that "cut" bleeds sometimes but it doesnt hurt at all. Im planning to go to the dentist but what are they going to do? get stiches to put it back together, cut it off (since its very small like a third of an inch) or just let it sit? And what is this?

Gum Problems or Wisdom Teeth.?
It sounds as if you are experiencing an impacted wisdom tooth. This would be a tooth that is either not at all erupted, or partially erupted, a condition caused by lack of space in the back of the mouth. This might lead to several unpleasant conditions, such as the infection pericoronitis. With pericoronitis, food and bacteria might collect under the gum causing a local infection that, if left untreated, can spread to other regions as far as the neck (nodes). However, it sounds to me as though you might have had some problems with this specific region of your mouth before, and the gum has "adapted" to close off the entry point for bacteria (hence the closed "flap" of skin). By contrast, the other side of your mouth (as we tend to be symmetrical) might develop similar problems with pericoronitis, and it might very well be that the gum does not form a "flap" here, but remains open. Regardless, impacted wisdom teeth generally are recommended for removal. Impacted wisdom teeth might occur if you brush and floss twice daily, or if you brush once weekly. Removing an impacted wisdom tooth will reduce the likelyhood of pericoronitis, periodontis, periodontitis, and tooth decay/bone loss in the back of the mouth, all very painful conditions in the long run.
Reply:I haven't brushed my teeth for three days, and no one has said anything yet.
Reply:lucky for you if you only brush your teeth 5 times a week, floss sometimes and yet you don't have any cavities. best thing to do is give your dentist a visit so that it can be resolved. i don't think you'd need stitches for that.
