I have TMJ and the grinding in my sleep has caused the roots of one of my teeth to begin curving. Because of this, I have been experiencing intense pain and nerve irritation, according to the dentist. So, I went to get fitted for a mouth guard but because I wasn't getting proper sleep, I used a sports mouth guard in the mean time which made the pain disappear. I wore this for 11 days until I received the mouth guard fitted for my bottom teeth. I began wearing this guard for 5 days and now my tooth pain is back. I switched back to the sports mouth guard on Sunday but my pain level is very high. I don't understand what to do because I know I cannot be grinding in my sleep as the sports guard is too thick and rubbery to allow that. I even attempted it while i was awake just to see if it was possible. I have tried ibuprofen for the pain but it does little. Please help?
