Cut on inside of upper lip won't go away

[flightlevel]

Hello,
first of all i am a 25 y/o male in what i believe anyway to be pretty good health. About a month and a half ago, maybe more, i noticed a sort of mild stinging sensation on the inside of my upper lip when i would push my tounge up there. when i curled my upper lip back to see, there was a small cut (about 2mm long) running up-down direction exactly in the middle. the stinging sensation was only there during the morning time immediatly after i woke up when i had very dry mouth. over the course of the day the cut would start to close a little bit, but would always return the next day after awaking and having dry mouth. this is NOT an ulcer or spot, it is a cut, and i am pretty sure i didn't do anything to cause this cut. But it's been a month and a half and it's still there. I have tried OTC canker sore treatments which really helped and the cut closed again, but it always reopens after sleep. any ideas? Thank you,
D

Thanks for the fast reply. What sorts of other things could cause this to happen?

Any sore or cut etc. that has not healed in 7 to 10 days should be investigated by a professional. I think a visit to an oral surgeon is in order. It may have something to do with the dry mouth issue but a consultation is necessary.
