Had broken partial crown replaced on #14 2 months ago with full Cerec crown. It's had 6 adjustments so far. Bite still off, tooth hurts/aches, is briefly sensitive to hot and cold. Dentist says it doesn't need root canal (he tested). Now premolars top and bottom starting to hurt from hitting hard. He says I have a "tight bite" hence need for careful adjusting. I had no pain or bite problems before. I'm taking advil all day, chewing on other side. Please help!
