Why Choose Root Canal Treatment?
A root canal is the ideal solution for teeth with:
- Deep decay or infection reaching the pulp
- Cracked or fractured structure exposing nerves
- Severe sensitivity or abscesses
By removing infected tissue and sealing the tooth, a root canal saves your natural tooth, prevents extraction, and restores function—all with minimal discomfort thanks to advanced local anesthesia.
