I had a second root canal on my bottom left first premolar four years ago. The tooth has ached for the past two weeks. I’m concerned that it is infected again. Is getting a third root canal on a tooth possible, or is an extraction likely? Thanks. Luna from Chicago
Luna,
Root canal retreatment is a standard procedure, but it’s essential to understand its limitations and potential outcomes. While it can be a successful option, factors can influence its effectiveness.
Root canal treatments require cleaning and sealing the infected pulp chamber and canals within a tooth. However, multiple or curvy canals make it challenging to fully clean and seal them. This can lead to treatment failure, even when a dentist performs the procedure correctly.
Why Might Root Canal Treatment Fail?
Common reasons for root canal treatment failures include:
- Complex canal anatomy: Teeth, especially molars, can have multiple canals and branches that are difficult to access.
- Incomplete cleaning: During treatment, a dentist may miss tiny fissures or side branches.
- Reinfection: Bacteria can re-enter the tooth through cracks or other openings.
Can You Get a Third Root Canal Treatment?
A third treatment can be effective, but its success rate is not guaranteed. Alternatives, including extraction and a dental implant, may be necessary if multiple attempts fail.
Root canal surgery, also known as an apicoectomy, is a more invasive procedure that involves accessing the root tip from outside the tooth. The method can be effective in cases where retreatment has failed, but it may not be possible or advisable.
Whether to pursue retreatment, surgery, or extraction depends on several factors, including the severity of the infection, the tooth’s location, and overall dental health. It’s important to consult with a qualified dentist to discuss your specific situation and explore the available options.
Consult a dentist with advanced root canal training or an endodontist (root canal specialist) to discuss your options.
