After abt a year. I got root canal done recently. Whole process took abt 4-5 sittings over abt 15days.There was one canal which was troubling me for 10 days but doctor said its just tissue and canal is clear and went ahead finalizing root canal process and fitting cap.Ceramic Cap was fitting yesterday.All seemed ok till lunch. But now from evening when I bite, the tooth pains. Even biting krackjack biscuit it pains.Doctor seems to be famous doctor (based on photos in his clinic) but now I dont know whats going on. Why the pain has come back? Has something gone wrong during root canal process? Did doctor neglect something?Thank you.
