How long does a root canal take?

A root canal usually takes about 60 to 90 minutes, and molars, which have more canals, can take longer. Many root canals are done in one visit; some take two, especially when there's a lot of infection or the canals are hard to reach. If the tooth needs a crown afterward, that's placed at a later visit. Dr. Chang will tell you what to expect for your tooth.

How much is a root canal?

The cost of a root canal depends on which tooth is treated, since molars have more canals than front teeth, and on whether you also need a crown. Dental insurance often covers part of a root canal, and we're in network with Delta Dental PPO and Delta Dental Premier. Without insurance, membership plan members get 15% off treatment, and CareCredit can spread out the cost. Dr. Chang explains the cost before treatment.

Does a root canal hurt?

The tooth is numb during treatment, so it usually feels a lot like getting a filling. Most of the pain people associate with root canals comes from the infection beforehand. Expect some soreness for a few days afterward; over-the-counter pain relievers usually handle it. If you're nervous, we also offer nitrous oxide (laughing gas).

How can you avoid a root canal?

The surest way to avoid a root canal is to treat cavities and cracks early, before bacteria reach the nerve inside the tooth. Regular cleanings and exams with digital X-rays catch decay while a filling can still fix it. Once the pulp is infected, though, it won't heal on its own, and the choices are a root canal or removing the tooth.

How long does a root canal last?

A tooth that's had a root canal can last for many years, often a lifetime, when it's properly restored and cared for. Getting a crown on a back tooth when it's recommended makes a big difference, since treated teeth are more brittle. New decay, a crack, or a leaking filling can cause problems later, and an old root canal can sometimes be redone.

Can I go back to work after a root canal?

Most people go back to work the same day, and most can drive themselves home. If you had nitrous oxide, it wears off within a few minutes after the mask comes off. Wait until the numbness wears off before eating, and avoid chewing hard food on that tooth until it has its final filling or crown.

WHAT IT IS

What is a root canal?

Treatment for the inside of the tooth.

Inside every tooth is the pulp, the soft tissue that holds the nerve and blood vessels. Deep decay, a crack, or repeated dental work can let bacteria reach the pulp and inflame or infect it. During root canal treatment, the infected pulp is removed, the canals inside the roots are cleaned and shaped, and the space is filled and sealed.

Some infected teeth don't hurt at all and show up first on an X-ray.

If a tooth can't be saved, the alternative is removing it and replacing it with a dental implant or a bridge.

Root canals are where Dr. Chang has focused his training. His continuing education includes the University of Michigan Endodontic Board Review, and he's attended the American Association of Endodontists annual meeting.
