I have new piece of skin opposite to upper eight teeth and i eat hardly?

Probably normal: The piece of skin to which you refer is likely the incisive papillae. It can become inflamed and feel larger than normal. Alternatively, it could be a piece of the roof of your mouth known as rugae, which are the rougher areas behind the upper front teeth. If the skin is bothersome, see a dentist to have it evaluated.

???: Your question is unclear, but if you have a change in your mouth, start by seeing your dentist. He/she will be able to tell you of this is normal or not, and offer your a course of treatment. Call today.

See dentist: Your question is not very clear. When you say upper 8 teeth, i assume you are referring to the cheek area next to the first bicuspid tooth, you may have a cheek biting habit, and if it continues you can create an "irritation fibroma" a benign outgrowth of the cheek tissue. If that is the case it can be easily removed, wear a nightguard, and please eat!
