hi mam/ sir I'm 30 years old. recently I consult dr for my RCT it was done. but dental dr said some cavity are there if you done the filling it will not create a problem in future.i decided to go with dr advice. dr filled my little bit cavities on two molars. it is only little bit cavity no pain nothing but he did composite filling on molar tooth. after the filling I feel sensitivity and pain on my tooth when only I bite. no cold and hot sensitivity. is that any problem with my tooth.
