Tooth Sensitivity after Composite Fillings. I always tell my patients that any time a tooth is drilled on, there is potential for some post operative sensitivity. The more work the tooth requires, or the deeper the cavity, usually results in more sensitivity. The range of sensitivity is different for every patient. In a normal-small to moderate size filling, sensitivity to cold temperatures usually subsides within a couple of weeks.
Grooves in your teeth should not cause sensitivity to chewing hard foods. I know 6 months seems like a long time but some teeth take a very long time to quit being sensitive after a filling. It is too bad that you had all four molars done at once and that all four of them got sensitive.
