Well good news.. the surgeon confirmed it as just a burn. He told me for a roof of the mouth burn it could take a month to heal. And it did not look suspicious to him at all. I dont know why my dentist told me that it shouldnt take more than two weeks but im guessing an oral surgeon must see this type of stuff all the time.well the good thing that came out of this is its been over two weeks since I have smoked a cig.
