Re: small hard bump after wisdom teeth extraction
It's probably nothing to worry about. You may have bit your check while you were numb and didn't realize it. It could be a "canker sore". It could also just be an area that was irritated during the extraction. Give it a little time and see if it gets better over the next couple of weeks. If it becomes painful or increases significantly in size then see your dentist, but my guess is that it will go away on its own. Good Luck!
