Just found your message that you would bet on dental cavitation contributing to my headaches, and I think you may be right. Thanks for the suggestion. I have a tooth that has been hurting. I have been to two regular dentists who tell me they cannot find anything wrong with it. I am curious as to what made you make that bet, and grateful that you did. I am going to look for a biological dentist tomorrow. Tired of taking all this pain killer crap.
