This is a problem that can be fixed easy, if you have a good dentist then there should be no problem with them getting this matter sorted ! I would allow your current dentist one more try at fixing the problem for you, and if he fails I would seek another dentist for a second look.
When your crowns where fitted did the dentist shave the tooth before they fitted, also did they use sand paper kind of things once it was fixed in place to make sure your crown was fitted ok and also get red of any xs stuff left from fitting.... I would also check that he didn't get drill happy and shave away too much.
Hope you get your bite back soon
