Hi, and I am sorry you are having trouble with your teeth. There is a woman named Bryanna, that is great with dentistry. You can private her also. I would say from what I heard, that your crown is hitting "high" You are feeling it when you bite down. This should not be. Your bite should be alright, before you go through the process of invisilign. Your dentist needs to correct the fitting of that crown. If it doesn't feel right it isn't right. Bryanna can answer you better than I can, thats for sure. take care ginnie
