Hi! I have a small hole in my upper left side teeth. I haven’t noticed it until there were tenderness and pain while eating, drinking something cold or hot. I’m planning to go to Sierra Dental Clinic in Calgary but I’m scared as I’m not sure what all will be the procedure to close that hole. I have heard fillings are used to fill small holes or cracks in the teeth. What materials are used to fill those holes? I have heard about composite dental fillings. I would like to know if anyone here had done this and is it effective?
