A week ago I had a checkup and told the dentist I was getting a sharp pain whenever I ate on one side and the pain was between two lower back teeth. She said I had gum erosion ( I am an older patient!)and painted some coating on the lower edges of the teeth. No mention of hope this works. There was no change in the pain so after 5 days I contacted the surgery and they told me to go back in. She showed me the x-ray taken on the previous visit and said there was no decay and it might be a hairline fracture which she couldn't see and therefore couldn't treat. I joked about eating on one side for years! I then asked whether I was using the most suitable sensodine and she gave me some duraphat toothpaste to try( she wasn't suggesting that until I asked). No invitation to go back if the pain doesn't improve. My dentist is NHS and I have been going to her for years. She is very nice and I have mostly been very happy with my treatment but don't quite know what to do now. I get tense whenever I eat. Even chewing a room temperature tomato made it hurt like hell. I would be really grateful for any advice.
