Killing the nerve of teeth would bring new problem for us ? I think many guys had experience of teeth ache ,so we had to see a dentist. And then they would tell us that a big problem on my teeth, I must be treated on root canal (I am not sure of this word exactly) , which means a piece of nerve would probably be moved out from my teeth once it was too bad. So my question is that killing piece of never would impact our health after teeth operation?
