DH and I starting going to a new dentist last year, and we like her flexible hours, however late last year she fixed cavities for us and even though it's been months we still gave sensitivity to the point that I can hardly chew on one side and DH is the same. I gave had cavities done before and never experienced this. When I asked her about it she said well sometimes it takes longer for the sensitivity to go away, but it's been months. Has this happened to anyone?
