I had a large filling 2 months ago. The dentist could not get my bite right after going back 3 times. Drilled the filled tooth that much that it now has a hole that I have to pick food from every time I eat something. Since then I have had a ringing in my ears. I saw my GP and he sent me for a hearing test, my hearing is good. He said that the ringing is coming from my bite being out. I went back to dentist and (not the dentist that did the work but at the same practise) He said he could probably fill the hole in the said tooth with some difficulty. And is going to refer me to an orthodontist for my bite. Should I get a second opinion?
