Thanks. Please let me know how things go with the Fullerton dentist, not just what he said, but if you thought it was dirty, etc., like the other person. I don't know if I have a cavitation, but I do get weird sensitivity in the same teeth from time to time that makes no sense and I have a ton of major health problems. My jaw if also tender to push on. I've had molar extractions, as well as two root canals. Oh and if you happen to find anyone else, please let me know. I'm in CA too. You can pm me if you'd like, as I don't get here too much. Thanks.
