OK, so I went to see a dentist a few weeks ago. I had no problems whatsoever. But he did a small filling on one of my teeth on the upper jaw. The part where the tooth and the gum meet. He warned me I might have sensitivity to cold for a while. But actually I didn't. What I had was a bit of discomfort when biting. A bit of pain. I thought it might go away so I did nothing. Then today I was drinking cold water and felt a lot of sensitivity. But this time another tooth, just below the one with the filling. I called the dentist. He assured me that it made sense. But I don't see why a lower tooth would become sensitive to cold?? The xrays didn't indicate any problems there. Dentist claims he needs to make an adjustment to the contour of the filling. Anyway, does it make sense? Why would I feel sensitive to cold in a totally unrelated tooth?
