Root Canal Therapy
Tooth pain that will not settle, and worried the tooth may have to come out? First identify the cause and whether the tooth can be saved.

What Can Root Canal Therapy Help You Address?
Pain will not settle
Persistent toothache or sensitivity needs a diagnosis; pain alone does not mean you need a root canal.
Swelling appears near a tooth
Tell the office when it began and whether it is worsening so an assessment can be arranged.
You want to keep the tooth
Ask whether the tooth can be treated and reliably restored, and what other options exist if it cannot.

Common Questions
Does every toothache need a root canal?
No. Tooth pain has different causes. An examination is needed before recommending this treatment.
Will I need a crown afterward?
Some teeth need a crown or another protective restoration. The choice depends on the tooth’s location, remaining structure and bite.
Can the tooth always be saved?
Not every tooth is suitable for root canal treatment or restoration. Dr. Hsieh will explain the findings and alternatives if keeping the tooth is not practical.
