There are various reasons as to why your teeth can be sensitive. If your dentist has not detected any cavities during your last check up it is possible that some recession of the gums could have happened since then. Also there may now be a tiny cavity which could have gotten slightly bigger since March. You can try a desensitsing toothpast like Sensodyne. If it doesnt settle see your dentist again (you are due for your 6 monthly chekc up any way).
