Found this site when I was researching jaw and sinus pain. I had 7 fillings replaced and three crowns. Since my first visit I have had much pain that has been described by others on this site... Upper left sinus, tooth, jaw, face - feels like it is going to shatter.... The dentist said it was because I now am grinding my teeth and need a mouth guard. I know I am more stressed around the face and may be clenching my mouth but I am pretty sure that I am not grinding them... Is this an appropriate treatment for the pain. I didn't really see anything about this in the other thread I looked at.

Thanks!
