Crowned tooth 6 on 11/12. Root canal 10 yrs ago on same tooth. 1st day: sinuses improved, shoulder and that side of my face loosened up, and body began to feel more relaxed than it has in yrs. Since: peaked and although not in pain, I feel like I only got a taste of what I'm supposed to feel like. Implant time? If so, what should I know? Poor hygiene as child, but on routine now. I've had 2-3 other root canals; teeth #4/3/2/wisdom pulled. Many fillings. Just want to feel ok again
