Endodontic treatment
Root canal treatment
A root canal removes damaged or infected tissue from inside a tooth, cleans the space and seals it, so the tooth can often stay in your mouth. It is for a tooth whose nerve has been harmed by deep decay, a large filling, a crack or an injury.
How long it takes
Most root canals take one or two visits, an hour to an hour and a half each.

Your dentist places the permanent filling or crown. We write to them after the visit.
Before you decide
Comfort
We use local anesthetic and test that it is working before we begin. Most people feel pressure and vibration, not pain. Raise a hand and we stop.
Other options, and waiting
Infected or inflamed nerve tissue does not usually heal on its own. Waiting can let the infection spread and may cost the tooth. Another option is to remove the tooth, and to replace it later, which your dentist can discuss.
Risks and after-care
Risks include a canal that is hard to find, an instrument that separates inside a tooth, a crack, soreness that lingers and an infection that returns. Dr. Krishnan explains the ones that apply to your tooth before she starts. Expect soreness for a few days, and avoid chewing on the tooth until it is restored.
How it is billed
We bill this as endodontic treatment, and give you a written estimate before it starts. We file claims with the plans we are in network with.
How fees work
Questions about root canal treatment
Will I need a crown afterward?
Often, yes. Your dentist decides, because a tooth with a root canal can be more fragile. The temporary filling we place is not meant to last, so book with your dentist soon.
How long does a visit take?
Plan on an hour to an hour and a half. If the tooth needs a second visit we tell you at the end of the first.
Can I go back to work afterward?
Many people do. The numbness wears off in a few hours, so plan lunch accordingly.
What if it still hurts after treatment?
Some soreness is normal for a few days. If pain gets worse, or you have swelling, call us; if swelling spreads to your face, eye or neck, or you have trouble breathing or swallowing, call 911.
