My teeth are constantly getting infected, and I have had root canals and crowns on most of my teeth. I come from a country where there is no fluoridation in the tap water, and my mother had terrible teeth, too, so I am not surprised. When I went to the dentist, he told me that the cause of my problems is that I have bruxism. I have never heard of this before in my life, and when he explained to me what it was, I thought it a little bit strange. He also asked me if I get headaches and neck aches, and I told him yes, I am an adult. This is a natural part of life, everyone has back and neck pain above forty! I would like a second opinion, could you please help me out with this?
