A periodontist has determined that when my dentist put a post in my (root-canaled) tooth before putting on a crown, he perforated the tooth, with the post positioned between the roots rather than inside a root... There is probably some gum infection and tooth now wobbles some. The periodontist is recommending extraction, bone graft, and implant. Are there any other options to treat and save this tooth?? I've heard some people get tooth roots "amputated" -- does that offer options for sealing a hole in the tooth, and replanting the post properly?? Are there any other questions I should be asking the dentist or options I should be exploring before I agree to extraction and grafting... Any perspectives would be much, much, much appreciated!
