There was a cavity in my mouth. And the doctor filled it with permanent filling. Then after filling, it starts paining. I consulted another doctor, he took x-ray of my teeth and said rct should have been done instead of permanent filling. He said the only way now is to uprrot the teeth and put on a cap. He has given me novamox and told me to take whenever it hurts and advised me to take this till the time it becomes unbearable and frequent. And then he will go for uprooting my teeth. What should be next course of action?
