The Basics

What You Need to Know

01

What is a root canal?

A root canal removes inflamed or infected nerve tissue from inside the tooth, cleans and sterilizes the root canals, then seals the space to prevent reinfection.

02

Why is this beneficial?

A root canal eliminates severe toothache, stops infection, and saves your natural tooth from extraction while preserving your bite alignment.

03

Will it hurt?

No. Modern root canals are no more uncomfortable than a filling. Deep local anesthesia completely numbs the tooth. You’ll feel pressure but no pain.

Questions

Frequently Asked Questions

Signs include severe toothache, prolonged sensitivity to hot/cold, darkening of the tooth, or swollen/tender gums. Dr. Yu can diagnose with an exam and X-rays.

A permanent crown is required after treatment to protect the brittle, treated tooth from fracturing during normal chewing.

Root canals have a very high success rate. In rare cases, reinfection can occur and a retreatment procedure may be needed.

Whenever possible, saving your natural tooth is the preferred outcome. Implants and bridges are excellent replacements, but nothing fully replicates your natural tooth.
