I am a 66 yo male in good general health, on fixed income, and with a total knee joint replacement. I have a cracked molar (31) with peridontal infection and significant bone loss (9 mm pocket). I have had no associated pain. The dentist believes that the crack involves the posterior root, and is the cause of the bone loss and peridontal disease. He believes the tooth is beyond saving and recommends immediate extraction. My pocketbook agrees but I must ask if extraction is the proper protocol vs. efforts to keep the tooth.
