I have visited the clinic to correct sharp edges on one of my tooth and the doctor done a filling on the same( I didn't have any infection.).After 2 minutes he removed the permanent filling & done the same thing again and he told me there was some bubble. After 3 weeks i felt a part of the filling had come out. Again I went to the clinic & he has done a little deep filling.As he was drilling it was paining for me.He advised me I can start chewing with the same tooth from today itself.But i couldn't as it was very sensitive to hot, pressure and tooth brushing.He advised me some gel but it didn't solve my problem.After 41 days the tooth was still irritating.so i went to another Dr. and he advised to take an X-ray and it shows the filling so deep and very close to the nerves.Now slight infection also there and I am on antibiotics.Now also my tooth is sensitive to hot & pressure and i feel jerk some times when I bite.I feel discomfort as long as I am awake.Will this problem will be cured with the medicines or Do I have to undergo root canal procedure?.What went wrong in the procedure?
