Root canal treatment. A period of time?

Hi, I know there is a prevailing myth recently that root canal is not good for general health. Its a big myth. There are millions of tooth being saved all over the world with the procedure called root canal treatment. When it's been done by a root canal specialist, as a patient u need not worry for anything. About your question regarding necessity, root canal treatment becomes absolutely necessary when u have to save your tooth instead of removing it. Of course u need to take an X-ray before starting a root canal treatment. But at times by seeing your tooth from outside, experienced dentists can say whether the tooth would really require a root canal treatment or not. So don't worry, just go ahead for the treatment
