It does not sound like cancer but you should have a dentist or an oral surgeon examine you to make sure. It sounds more like pericoronitis, which is extra "gum" tissue over the wisdom tooth that can get infected and can cause pain when biting.
It could be an absess, where food or bacteria got into an opening in your mouth and is now infected. I would contact your dentist as soon as possible
Thank you doctor for the quick response. I saw my dentist this morning and he said that what he saw was also pericoronitis. Sometimes a second opinion can settle the mind down. Again, thank you for your time and knowledge on this board. It is a wonderful resource for the public.
I have a lump over my top right wisdom tooth and i dont exactly no what color it is it herts badly at all times and it has been there for a few weeks and i cant exactly afford to go to a oral sergon or anything and i do not have any insurance i was just wondering if i should be worried about it being a tomer or somethig like that please let me know as soon as possable
