What is a Root Canal – FAQs

What Is a Root Canal? A root canal is a dental procedure that an endodontist performs on your teeth under certain circumstances. We will first take an X-ray of your jaw after which they will secure your tooth. After we have secured your tooth, we will drill a hole in your tooth to extract the dental pulp that will also get rid of bacteria or infections. After we extract the dental pulp we will clean the inside of the tooth and close it.

Will the Root Canal Be Painful?

While preparing you for the procedure, the first thing that we do when you are in the chair is to give you suitable anesthetic. Although under most instances the nerve within the tooth is dead, we still administer you anesthetics to ensure that you are comfortable during the procedure.

It is also important sometimes as the cleaning can cause some discomfort, but it is nothing that you should be afraid of.

How Long Will a Root Canal Last?

A root canal is not the most time consuming procedure; rather, it can take around 30 to 180 minutes to properly extract the inside of the tooth. If you happen to have minor decay inside your tooth, then the procedure may not take more than 40 minutes.

On the other hand, if you have deep decay or an infection within the root canal, we will then need two sessions each of about 90 minutes.

Can a Root Canal be redone? If so, why?

Yes, it is possible for you to get a root canal redone. Although it is possible for bad root canal treatments to not need further care, it is possible in case a previously done root canal treatment goes wrong or happens to get infected. In this scenario, you can indeed ask your dentist for a retreatment, where they will treat your tooth again. This is even possible if you happen to switch dentists or endodontists.

Will there be Pain after the Procedure?

After receiving a root canal it is very common for people to experience some pain in their teeth, usually in the form of tooth tenderness. During the first one or two days it is possible and normal for you to experience some pain that will be either sharp or incredibly dull.

Swelling is also normal when it comes to post root canal procedure, but it tends to heal over time. You may also experience a sharp sensation when chewing, so stick to fluids and semi solid foods.

Will I need a Crown after my Root canal?

A crown is not always necessary; if you receive a root canal procedure for your front teeth, no crown is needed. That being said, a crown can greatly strengthen your teeth and you won’t have to make consecutive trips to the dentist.

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

A root canal is not necessary if you have recently received a dental crown. A root canal is only necessary if you happen to have cavities or infections deep within the tooth.
