I had a retreatment root canal done after the original one was done ten years ago- it became absess. After it was done the infection spread to my whole side of face and couldn’t be drained as it was spread through my face not a single spot. It was severe. Antibiotics cleared it. Clindamycin. The pain persisted though I have discomfort in the jaw spot same area but the tooth does not hurt for pressure nor it isn’t sensitive to hot or cold anymore but my jaw is throbbing - dentist put me on two weeks more antibiotics- swelling is better but pain is still there. Endodontist I called and they said give it another month. They said if not better they will do a procedure to cut root on side of gums but how do they know this will work without a 3D scan to know the problem even and will it work forever or temporarily- should I just extract the tooth and get implant. All three dentist don’t know why it hurts regular X-ray shows fine. Do I live with pain or fear it’s hurting bone. Swelling is down but my pain persists. Please help.
