So my SO started grinding his teeth in his sleep a few weeks ago and I hate it! Plus I know it's bad for your mouth and teeth so whenever I catch him doing it I'll gently stroke his face and it seems to stop him for the time being. Does any one else had this problem with their SO? If so what helped you?
