Q. Hi i went to my dentist about 18 monthes ago and he said i needed a new denture and my top tooth next to the eye tooth was twisted.(this tooth had a white filling in it and had never beeen any problems.He persuaded me to have it crowned which i was against.every since i have had a knawing pain which feels like its the eye tooth.my dentist dosnt really listen to what you tell him and ended up doing two root canels on the tooth he had crowned. he done the last one through the tooth and then put a mecury filling in which i wasnt pleased about. cheapest i think.i keep trying to tell him the crowned tooth aches all the while unless i take my denture out.for the last 18 months i have pain/burning in that side of my face.it goes into the ear.this is wearing me down. the dentist will not have its anything to do with the crowned tooth and says ive probably got TMJ and to yawn with my mouth shut and cut up my food. sadly im nhs and once you have paid your fee they dont want to know.i have took antibiotics and anti inflammatorys but these do not help.as i said no problems with that side of my face or teeth until i had that crown and root fillings. please any suggestings.
