Root Canal Treatment
Root canal therapy removes diseased tissue from inside the tooth, halts the spread of infection, and restores the healthy portion — saving a tooth that would otherwise need to be extracted.
About this treatment
Root canals are tiny passageways that branch off from beneath the top of the tooth and run down to the tip of the root; every tooth has between one and four. When infection reaches the inner pulp — the chamber containing blood vessels and nerves — it causes pain and sensitivity, and can lead to abscesses if untreated. A traumatic injury can also compromise the pulp and trigger similar problems.
Root canal therapy is a remarkable treatment with a very high success rate. Before it was developed, the only option for a diseased tooth was extraction. Today the procedure typically takes one to three visits: a small access hole is made through the top of the tooth, the diseased pulp is removed, the inner chamber and canals are cleaned, disinfected, and reshaped, then filled with an elastic material and sealed. A crown is usually placed afterward to fully protect the tooth.
What to expect
Every visit is built around your comfort. Here's the typical journey:
- 1
Diagnosis
X-rays confirm the infection and map the canals before treatment.
- 2
Comfortable numbing
The area is fully numbed before any treatment begins.
- 3
Cleaning the canals
Diseased pulp is removed and the canals are disinfected and reshaped.
- 4
Sealing & crown
Canals are sealed with an elastic filling; a crown is usually added to protect the tooth.
