The nerve inside a tooth can be infected by untreated decay or trauma.
The nerve dies and the tooth can often be saved with root canal treatment instead of extraction.

The inflamed or infected pulp is removed and the inside of the tooth is carefully cleaned, disinfected and then filled and sealed.

Root canal treatment usually requires more than one appointment with local anaesthetic.

All root canal treated teeth should have a crown (cap) placed.  This will protect the tooth and prevent it from breaking, and restore it to its full function. Root canal treatment is highly successful and usually lasts a lifetime.

Dr. Chao generally provides root canal treatment on most anterior and premolar teeth
and usually refers more complex molars to specialists (endodontists).
