Thanks for your help guys. For the sensitivity, I will try the toothpaste and hang in there.
With the jaw issue, I have had my bite adjusted a couple of times now and he is sure it's right and I can't feel any teeth hitting when I bite. I went to a chiropractor and he adjusted my jaw (in fact been twice) but it just seems to ease a bit and then get sore again. It is really getting on top of me cause it is so painful. Plus after all the effort I made to get my stomach and liver healthy again and now here I am taking painkillers! I said I wouldn't do that again!
