i recently got one of my decayed tooth restored with a composite filling. after doing the filling , my dentist asked me to bite on a carbon paper and made some adjustments, and the tooth was completely fine. but the next day when i was eating corn, i felt a sudden pain on that tooth. from that time onwards am having pain on that tooth on and off, whenever i bite something hard over there. the tooth is comfortable when i take a soft diet. i went back to my dentist and had a check up again with marking paper and there was no excess filling!
i was adviced to wait for a week and come for a check up after a week. what is the actual problem with my filling?
