I have pain in tooth 46 for more than 2 years. Have tapping and biting pressure pain on it. Xrays and CBCT scan was clear. Endo suggested Root canal for these symptoms. Had RCT and no changes. Had retreat in distal canal last year as that wasn't filled properly the first time. No relief. CBCT scan taken again and clear. Same tapping and biting pressure pain on it and constant pain in this tooth and hurts for pressing with fingers, rubbing with tongue etc Endo reopened the Tooth and placed calcium hydroxide dressing inside the tooth yesterday. Opened both the canals. Tooth is still painful and no changes yet. Tooth is throbbing and feel like vibrating inside the tooth. It's like wiggly wobbly and feel like it's coming out of the socket. If I have mouth full of water, it just throbs and tooth feels like vibrating. Same for eating food. Even while talking too. Never felt this symptom before on this tooth. Is this normal or I need to extract it ASAP?.I am taking pain killers.
