I had my molars -wisdom tooth removed. I face this issue of sore that keeps occuring on the joint of jaw. This issue earlier used to happen because of disoriented molar causing irritation on that area. But now the molar had been removed and I still find it occuring. There is no pain or irrigation, but just a bump that goes away itself. At times the bump/sore have some liquid in it. Is this the cause of concern and why it is happening?
