crown has ruined my bite

I had a crown on #18 done which was so high I could not close my mouth.
After several adjustments I was told it could not be adjusted anymore.
I was in excrutiating pain for 3 weeks, then had the opposing tooth and crown adjusted several more times to make it fit into my mouth and relieve the biting pain I was having.    I feel now that the crown fits in my mouth but the tooth next to it is hitting very hard.
I've been to several other dentists and am told to give it more time for my mouth to adjust but my bite is not correct.
If it is too low, wouldn't it be best to redo the crown?  What is the risk of losing the tooth or needing a root canal in the process?  Is it possible to get comfortable again?  It has been 3 months since the permanent crown was put in and I am still miserable.

I know exactly what you mean.   You feel so uncomfortabe with your bite and all you want really is for someone to get it back to the way it was.   A similar situation happened with me where I had a root canal done through an old crown on a bottom molar by an endodontist, and through the process the tooth was reshaped slightly.   But even with the slight adjustment, it caused the teeth to the left and the right of it to start being hit much harder by the opposing teeth on top.   I was so uncomfortable that I went to my regular dentist and told him I needed something done to make me feel more comfortable.   He wasn't too happy with messing with the other teeth because he also said maybe I just needed to get used to it after so much work had been done on the recently root canalled tooth that was already crowned.   I sat in the chair and told him quite sternly that my bite had been changed and I was feeling most uncomfortable!   He did the test with the piece of carbon paper thingie and got me to bite down hard several times.   Well he obviously could see straight away that there were marks from the paper left on the teeth (which I take it there shouldn't be any marks left when you do a biting test).  On one tooth he shaved down the part where the mark was and with the other tooth he actually shaved a part of the cusp on the opposing tooth above.   And he only had the high speed drill on each tooth for probably no longer than 5 seconds!   When he stopped after those few seconds I thought to myself "well that couldn't have done much to help it", but wow, when I closed my mouth to test it, the teeth were not getting hit.  The drilling was so minimal.   The point of this story is that sometimes all they need to do is take the tiniest little bit off a tooth, which can take all of a few seconds literally and you can feel the world of difference immediately.   Good luck with it......has anyone done the carbon test on your tooth next to the crowned one to see how much of it is being hit?
