Thanks, and I will read all your posts and copy them for my housemate. I will give her this one to start with. Nan really wants to know the truth, but doesn't believe it. Right now I don't want to keep my one RC tooth in. I always wondered why I had sensitivity to it. I was told a bunch of stuff too. Again, looking forward to information to pass on. We have to get educated Bryanna, and so does my housemate. ginnie
