Q. My problem is sensitive teeth and it is really getting me down. I have visited my dentist twice and told her about it, she has taken x rays and done a bite test and nerve vitality test. She just recommends sensitive toothpaste. The thing is its specifically 2 teeth, my others are fine. The first sensitive one had a composite filling put on to repalce a silver one about a year and half ago. Its the right side upper back tooth. The filling caused nothing but sensitivity! I pur up with it for ages then eventually had it redone, which has helped but not 100% non sensitive. Also the dentist thought she saw a slight crack in it while redoing it, I think she put some desensitiser in it as well. The other sensitive tooth is the lower back tooth directly under the filling one. This is the odd one that the dentist cant find anything wrong with. It is sensitive most days to a greater or lesser degree. It is triggered by hot and cold and sometimes biting. Also since having this filling and onlay the other side I feel that my bite has never felt quite right since I get an aching in my bottom jaw at times too i think from the nerves in the teeth. The other sensitive one is the lower back tooth, directly under that filling
