I’ve had TMJ for years and wear night guard due to grinding my teeth. My CT scan last year shows arthritis in my jaw. I had a rare internal resorption on bottom front tooth and it was removed just before I was diagnosed with PMR. So no implant for me, just empty and really worried over time, the teeth can shift backwards and be totally useless, not to mention pretty darn ugly. Jaw bone may never be able to accept implant but, so far, I can’t get answer. I’m still trying to figure out someone who can answer questions on this and have dentist appointment tomorrow but they are not TMJ jaw health experts. Perhaps I should do some digging into that too.
