Root Canal Treatment

Everything you need to know about root canal therapy.

What is a Root Canal?

A root canal is a dental procedure that treats infection at the center of a tooth (the root canal system). It removes the infected pulp, cleans the inside of the tooth, and seals it to prevent further infection.

When is it Needed?

Root canals are needed when:

  • Deep cavity reaches the pulp
  • Cracked or broken tooth exposes pulp
  • Repeated dental procedures on same tooth
  • Trauma to the tooth
  • Severe infection or abscess

The Procedure

What to expect during treatment:

  • Local anesthesia numbs the area
  • Rubber dam isolates the tooth
  • Opening made in crown of tooth
  • Infected pulp removed and canals cleaned
  • Canals shaped and disinfected
  • Canals filled with rubber-like material
  • Tooth sealed with filling or crown

Recovery

After your root canal:

  • Some sensitivity is normal for a few days
  • Over-the-counter pain relievers usually sufficient
  • Avoid chewing on treated tooth until crown placed
  • Most people return to normal activities next day
  • Follow-up appointment for permanent restoration

Success Rate

Root canals have a high success rate of about 95%. With proper care, a tooth that has had a root canal can last a lifetime. The key is protecting the tooth with a crown and maintaining good oral hygiene.

Frequently Asked Questions

Is a root canal painful?

Modern root canals are no more uncomfortable than getting a filling. Local anesthesia ensures you feel no pain during the procedure. Most patients report the experience is similar to getting a regular filling.

How long does a root canal take?

Most root canals take 30-90 minutes, depending on the tooth. Front teeth with one canal are faster, while molars with multiple canals take longer. Complex cases may require two visits.

What is the alternative to a root canal?

The only alternative is tooth extraction. However, losing a tooth can cause other teeth to shift, affect your bite, and require replacement with an implant, bridge, or partial denture—often more expensive than a root canal.

How much does a root canal cost?

Root canal costs vary by tooth: front teeth ($300-$1,500), premolars ($400-$1,800), molars ($500-$2,000). A crown is usually needed afterward ($800-$1,500). Insurance typically covers 50-80% of the cost.
