I have a hole above my right second bicuspid i have had heaps of trouble with this tooth for years and now there is a hole about 5mm above my tooth on my gum it is about 2mm long and 1mm wide there is nothing actually protruding from the hole but i can put my finger nail into the hole and there is a tooth in there. Would this be my second bicuspid some how breaking through my skin or could it be a new tooth. I have had many xrays on my teeth in the past and there has not been any evidence of another tooth. It has me worried because i don't want there to be something wrong with my gum like a disease or similar. If it makes any difference im 26 years old.
