Pleas can anyone help. I had a filling done a month ago (top molar) and im sure at one point during the procedure the dentist hit my lower tooth. When i got home and that lower tooth had a dent in the tooth. It didnt cause me any pain and i didnt go back to dentist however now its causing me sensitivity when eating sweet things ok with cold and hot. I really dont want another filling can anyone recommend what treatment the dentist can do. Also how do i say to him oh by the way i think you did that last month. Photo has been attached.
