So I'm fed up and desperate. Back story...changed dentist, they suggested they re do a filling I had done years ago as they think they can see decay. Goes ahead and confirms this is correct. Few days after the filling I start to get a sharp sensitive sensation whenever I eat or drink/breathe in cold air. Go back and they file it n tell me to make another appointment if that doesn't fix. Been back again n it's still not right despite more filing. What do I do? Go back again or get another opinion :(
