Had R/C 4 mths back on upper RIGHT molar & have temp.crown right now. If I touch that tooth/rub my tongue at the base of the crown, I feel like someone scraping tooth with a metal instrument. Can't eat that side. Dentist #1 and another Endo checked R/C tooth bite -said its proper. 3 weeks back another tooth- upper LEFT molar began hurting. Consulted another dentist. He said both problems are classic of TMJ & need treatment- i.e. Splint + bite-reconstructive work, combination of fillings/RC/Crowns/Alignment- huge amt.& years of treatment. I grind my teeth and get headaches SOMETIMES, but don't have ALL classic TMJ related problems. Before R/C I had no such problems. HELP- without doing TMJ treatment how can I be free of this metal sensation inside my tooth? Am getting sick of it and now with both sides paining cannot eat properly.
