I recently visited a local dentist after a long hiatus. Surprisingly I had no cavities but I needed a root canal and crown on #18 and another crown on #31. Following the root canal on 18 i was prepped for the crown and fitted with a temp. I returned two weeks later for the permanant crown on 18 and to be prepped on 31. The crown was too high and the dentist liked the anatomy of the tooth so rather than grind it to size he sent it back to the lab for correction. Another two weeks later I returned to get both permanant crowns. 18 was a good fit and needed very minor adjustment and feels just like a normal tooth. 31 however was quite high and the dentist proceeded to grind it down so it was a good fit. However the anatomy of the tooth is completely altered. It is completely smooth and round and does not feel like a tooth at all. Shouldnn't he have sent back 31 to get resized like he did with 18? What should I do?
