I'm not sure if I am having a cavitation or not. I have to have a root canal tooth pulled and the socket cleaned. How much that will cost, I don't know. I'm trying to build up the courage to have it done, lol. I am very phobic of the dentist and as much as I would like the tooth gone and as much as I know I am getting daily poisoning from the mercury, it's still hard to be able to get it out. Last time I had a tooth extracted my pulse went over 130 I was so terrified.
