question: Hello my name is Pura, I am 15 years old (if that matters tooth wise) and I have a question about tooth #14. I had a filling done in tooth #14 about a year ago and it is really sensitive to cold (even to saliva ejectors at times; I feel the cold air from it). My filling was apparently really close to the nerve and I was told that I’d be fine. Ever since the filling was done, (the filling is metallic by the way), was when I became sensitive to the cold (cold liquid doesn’t affect me, only when it is directly put onto my tooth –like when I go in for cleanings). My dentist has recommended a Root Canal procedure but the thing is, I don’t feel any pain with it except for the sensitivity. Any recommendations or explanations of this? Thank you for your time.
