Root Canal FAQs

What is a root canal?


A root canal is an endodontic procedure that endodontists perform. It mostly involves extracting the pulp inside your tooth in order to preserve the tooth, or to clean it. It is an incredibly complicated procedure, as there are a multitude of different nerve endings that they must be careful of.

It can greatly reduce pains and aches people have inside their tooth and can save them from a variety of different dental ailments.

Will the root canal be painful?

No, it will not be. We will first administer suitable anesthetic before starting the procedure. This anesthetic ensures that there is no pain during the operation; although the nerve is already dead, a dentist will still give you anesthetic to ensure that you stay comfortable during the operation. The anesthetic will keep you calm, and allow the dentist to properly perform the procedure.

How long will a root canal last?

However, if the situation is very serious, then your dentist may even have two different therapy sessions, each about 45 minutes. In most cases, a root canal does not take more than 90 minutes.

Can a root canal be redone? If so, why?

A root canal can definitely be redone, regardless of the severity of your situation. While an endodontist may ask you for a little more documentation on your previous treatment, it is possible for them to redo the entire procedure.

Even if you have a crown on your tooth, they will still be able to properly redo the entire procedure.

Will there be pain after the procedure?

During the procedure you will not feel any semblance of pain as you will be under the influence of anesthetics. That being said, it is very common for anyone to experience a sharp sensation in their teeth for at least a week.

By the second week the pain will begin to fade. The effects of the anesthetic do not last for more than three hours.

Will I need a crown after a root canal?

crown-post-root-canal-steps-03A crown is often put on top of a tooth in order to keep bacteria out, but it is only necessary if your dentist doesn’t seal up your tooth properly. Depending on the severity of the procedure, it is very common for dentists to tell you whether you must get a crown or not.

I just received a crown; will I need a root canal?

In most cases, a root canal is not necessary once you get a crown. Unless that crown happens to give you an infection, or is not placed properly, there is no need to get a root canal.
