A 33-year-old member asked:

what is the difference between root canal therapy and extraction?

Big difference: An extraction is final. The tooth is taken out of the mouth and is gone unless replaced some type of appliance, be fixed or removable bridge or implant and crown. A root canal is done to preserve the tooth when the nerve is affected. The tooth can remain in the mouth after a root canal without vital nerve tissue providing it has good bone support.
Dr. Edward Zuckerberg

Saving the tooth: With root canal, the dentist saves your tooth as opposed to removing it.
Dr. Gary Sandler

Big difference: Root canal therapy is a procedure to save the tooth and entails the complete removal of the nerve and all tissues inside the canal or canals of the root(s) of the tooth. The canals are then instrumented and shaped, dried and filled. An extraction is the removal of the tooth in its entirety.
Dr. Alex Shvartsman
Cosmetic Dentistry 25 years experience
BIG: Root canal therapy has the potential to save a tooth, while extraction is the removal of the tooth.

A 40-year-old member asked:

Can root regrow after having root canal therapy?

3 doctor answers8 doctors weighed in
Dr. Craig Fisk
Dentistry 12 years experience
No: Any tooth structure removed during root canal therapy will not regrow. However, only a small amount of tooth structure is removed through the center of the roots. So is the pulp which is also in the canal area. The root as a whole is still functional after it is filled.

What happens during root canal therapy?

A few steps: The dentist uses a handpiece to open up the top of the tooth to get to the pulp chamber. They then remove the dead or infected pulp, clean out the canals and put a filling material in the canal. This can take 1 or 2 appointments.

Can you please give me a technical description of root canal therapy?

4 doctor answers11 doctors weighed in
Dr. Shawn Murray
Dentistry 15 years experience
Root canals: It's simply removing the nerve and blood supply from inside the tooth because it has been contaminated with bacteria. Then you must fill the inside of the tooth so it doesn't get recontaminated.
