I got throbbing pain in my first and second upper premolar on the right side. The dentist after doing various tests and x-rays said the 1st premolar was abscessed and the 2nd premolar was dying. He put me on antibiotics for a week. He said I would have the abscessed tooth extracted because it was badly decayed. As for the dying tooth, he wanted to leave it, wait, and see how it goes. If it will start to give me any problems, he will have to extract it also. Is there a chance to save a dying tooth? What are the risks involved in keeping it? Any advice would be very much appreciated.
