He had a mark on his chik towards the inner teeth for the last 5 months which we showed to the doctor also and he said it was normal. When I showed it to the dentist, he said that it is happening due to tooth decay, so he got the upper molar removed, but now it has become thick and has grown out, what should I do now, what are the symptoms? Should we get diapsy done or is this normal due to friction..please give me good suggestions .I am also attaching the photo of the throat.
