Hello I have hard lump on the side of my lower right jaw. I had my wisdom teeth extracted 9 -10 weeks ago. The lump is restricting my mobility of my jaw. However , I dont believe it to be under the jaw it is to the side of the jaw and is causing some visible swelling to an onlooker. The bump is HARD, not soft, which was peculiar. Is it an infection, bone fragment, what?
Hello, thank you for consulting with Chat Doctor. Sometimes after the extraction of wisdom tooth the swelling arises, but it heals within a week.  But as you are mentioning that you had your extraction 9-10 day aback then it OS something problematic, it can be possible that a root fragment might have left still in the socket, which is causing this.  Better that once you get an x-ray done of that area or full mouth x-ray called as OPG, as it will show the cause. Hope it will help you.
