My teeth are a mess. I have a major lifelong grinding and chewing problem. The bottom set are very worn down, the top front teeth have crumbled in the past from chewing and I have crowns. I have numerous fillings and root canals and there are ominous cracks in several others. Is there a way I could solve this problem once and for all? I'm talking about fixing the teeth falling apart, not curbing the grinding. Assume cost is not an obstacle.
