Root canal therapy is a successful procedure that can save a tooth from extraction. A recent study found that teeth treated with a root canal have over a 97% survival rate after 10 years. Unfortunately, some patients can experience complications, which may require root canal retreatment. Here’s what you need to know if your dentist has recommended another root canal.
When is Root Canal Retreatment Necessary?
According to the American Association of Endodontists, between 5-10% of patients may experience complications after root canal therapy. Common causes of retreatment include:
- Narrowed or curved canals
- Complicated oral anatomy
- Delayed crown placement
If the root chambers were not cleaned properly, which can occur if they are narrow, curved, or complex, bacteria can remain trapped in the tooth. Delaying crown placement increases the risk of new bacteria infecting the tooth.
New issues can also jeopardize the success of root canal therapy, which may occur several years later, including:
- New tooth decay
- Damaged crown or filling
- Tooth fracture
Root Canal Retreatment VS Tooth Extraction
Extracting a problematic tooth may eliminate the issue at the source, but it opens the door to a new list of complications. Every tooth is essential for a healthy, functional smile. You’ll be at risk of several dental problems and you’ll need a prosthetic tooth to fill the space. You can face higher dental expenses from the consequences of losing a tooth. Root canal retreatment will save your tooth, so you’re less likely to need costly dental work later.
What to Expect with Root Canal Retreatment?
Root canal retreatment is similar to your first procedure. After numbing your mouth, your dentist will remove your restoration and the material that was placed within your tooth. They will remove any new areas of decay or infection, thoroughly cleaning out the root chambers. Your tooth will be sterilized before being resealed with gutta-percha. Your dentist will place a restoration over your tooth to protect it.
If you need a repeat root canal, don’t wait until it is too late. After retreatment, you can enjoy long-lasting results by committing to good oral hygiene and regular dental care.
