Q. My mom is and has been in excruciating pain for the past 10 days. She was told by her dentist a while ago that she grinds her teeth and was given a guard which she wears occasiionally. We have been to her dentist and the dental hospital a few times now, other than telling her what she already knows and making a further appointment to look at the fitting for the guard they have not been able to help… I cant express enough how much continous pain she is in. Her face is being swell down the side she is in pain, she is taking pain killers but they are having no affect….please advice ASAP…thankyou,
