Root Canals

What is a Root Canal?

A root canal is a dental procedure used to treat and save a tooth that is severely decayed, infected, or damaged. The procedure involves removing the damaged or infected pulp (the soft tissue inside the tooth that contains nerves, blood vessels, and connective tissue), cleaning and disinfecting the inside of the tooth, and then filling and sealing it to prevent further infection.

Why Is a Root Canal Needed?

Repeated Dental Procedures: Multiple procedures on the same tooth can cause irritation or infection of the pulp.
Cracks or Chips: A cracked or chipped tooth can expose the pulp to bacteria, leading to infection.
Injury: An injury to a tooth, even if it doesn’t visibly crack or chip, can damage the pulp.
Abscess: An untreated cavity can cause an abscess, a painful infection at the root of the tooth.

Common Questions

Why do I need a root canal?

You need a root canal if the pulp inside your tooth is infected or damaged due to deep decay, repeated dental procedures on the same tooth, cracks or chips, or injury. If left untreated, the infection can spread, leading to an abscess, bone loss, and severe pain.

Is a root canal painful?

Despite its reputation, a root canal is not typically painful. With modern anesthesia and techniques, the procedure is similar to getting a filling and should not cause more discomfort. Any pain you might feel before the procedure, due to the infection or damage, is usually more severe than the procedure itself.

How long does a root canal take?

A root canal procedure typically takes about 60 to 90 minutes. In some cases, it may require more than one visit, especially if the tooth has multiple canals or is severely infected.

What should I expect after the procedure?

After a root canal, it’s normal to experience some mild discomfort or sensitivity for a few days. Over-the-counter pain relievers can help manage this. You should avoid chewing on the treated tooth until it is fully restored with a permanent filling or crown.

Will I need a crown after a root canal?

In many cases, a tooth that has had a root canal will need a crown to restore its strength and function. This is especially true for back teeth (molars), which are more involved in chewing. The crown helps protect the tooth from fracture and further decay.

Is there an alternative to a root canal?

The main alternative to a root canal is tooth extraction, followed by options to replace the missing tooth, such as a dental implant, bridge, or partial denture. However, saving the natural tooth with a root canal is generally preferred when possible.
