I had a cap put on a tooth and got vertigo after. If you take a piece of ink paper in your mouth bite down and look in the mirror you can see where all of your teeth are hitting. Most likely that tooth is taking an uneven load. You need someone who specializing in reshaping the teeth. Your dentists wont' say theres a problem because then he has to replace the crown at his cost. This can also happen with regular fillings being done wrong and can throw off your bite. check out http:\\www.austindental.com\tmj.shtml they explain it so its easy to understand. Be real careful who you choose to fix it they understand about reshaping teeth or they can make the vertigo worse. Also try typing in Balanced Jaw and they will show how a bite being thrown off by your dentist can cause this and many other problems. Hope this helps
