I am grinding my teeth a lot during sleep on a regular basis. I have no stress. I do not smoke, drink coffee, tea. Just a regular healthy diet. I used to work in graveyard shifts two years ago for about a year from where this actually started. I have visited doctors but no one helped. I have to use mouth guard to stay protected from bruxism but guess what it pains a lot. I can not eat properly as I can feel my teeth are getting aligned with the shape of the guard. Its really disgusting. One doctor said that I have worms in my stomach. I had tablets but no result. Please update. T guard's hanks.
