I am under rct. One tooth is totally destruct but unable to remove bcz of no part outside the gum. Second near by tooth is half damaged for which I am taking rct. Two sittings wewe OK I nt too much pain or swelling. But from third sitting I am feeling continuous pain and go to dentist for relief earlier than appointment. He again treated and said bcz of pus it is paining. I want to know wat is the correct treatment for my tooth. Now I am paining in my jaw also. Is this a surgical issue or just rct is enough. And any HeLpful painkiller but not harmful for other organs. Please suggest.
