My dentist has told me I need to get root canal treatment done on my front tooth, and once thats finished I need to get a veneer. I got root canal done on another tooth a few years ago and I never went back to the dentist again for a few years.

I really want to know what are the benefits of getting the root canal or is it really necessary?
