Root canal

Root canal treatment

A root canal removes infection from inside a tooth and saves it from being pulled. If you have severe tooth pain, swelling, or a tooth that aches long after hot or cold, you may need one.

It's easier than you think

Root canals have a scary reputation they don’t deserve. With modern numbing and techniques, most patients say it felt like getting a long filling. The pain people associate with root canals usually comes from the infection itself, not the treatment. The whole point of a root canal is to take the pain away.

What's actually happening inside the tooth

Inside every tooth is a soft core called the pulp, which contains nerves and blood vessels. When deep decay, a crack or an injury lets bacteria reach the pulp, it becomes inflamed or infected. Because it’s trapped inside the hard tooth, the pressure builds, and that causes the intense, throbbing pain. Left untreated, the infection can spread to the bone and form an abscess.

Signs you might need a root canal

Sometimes an infected tooth causes no pain at all and only shows up on an X-ray. That’s another reason regular checkups matter.

What happens during a root canal

01

Numbing.

We numb the tooth and the area around it thoroughly.

02

Opening the tooth.

We make a small opening to reach the infected pulp.

03

Cleaning.

We remove the pulp and carefully clean and shape the inside of the root canals.

04

Sealing.

We fill and seal the canals to keep bacteria out.

05

Protecting the tooth.

We place a filling, and in most cases, a crown at a later visit to keep the tooth strong.

Recovery

Most people go back to work or school the same day. It’s normal for the tooth to feel a little tender for a few days, which usually responds well to over-the-counter pain relief. Avoid chewing hard foods on that side until your permanent crown is in place.

Root canal or extraction?

Pulling a tooth can seem simpler or cheaper at first. But a missing tooth lets neighboring teeth shift, can change your bite, and often needs to be replaced later with an implant or bridge, which costs more. In most cases, saving your natural tooth is the better long-term choice. If a tooth truly can’t be saved, we’ll tell you honestly and discuss extraction and replacement.

What a root canal costs

The cost depends on which tooth is treated. Front teeth have one root, while molars can have three or more, which takes longer. Most insurance plans cover part of a root canal. You’ll get a written estimate that includes the crown, so there are no surprises.

Why saving the tooth matters

A treated tooth can last a lifetime with good care. Keeping your natural tooth means you won’t need an implant or bridge later, your bite stays the same, and your jawbone stays healthy.
