The root canal is very expensive because of the labor that the dentist provides. It is, however, a good way to save the tooth. When I was a high school student, my mother brought me to her friend dentist to check on my teeth. There were 3 or 4 bad teeth that needed root canal. when the first tooth was done, I promised not to have another root canal. It was painful so I preferred the bad tooth to be extracted. I don't think it is worth the pain to have a root canal. What is your stand on this issue?
