A root canal may sound intimidating, but it’s actually one of the most effective and proven ways to save a severely infected or damaged tooth. Patients often ask, “How long will a root canal last?” The answer? With the right treatment and care, it can last a lifetime.
At ProGrace Dentistry, a trusted dental clinic in Northwest Calgary, our team has years of experience performing successful root canals. Using advanced dental technology, we help patients eliminate pain, prevent reinfection, and restore their teeth for the long term.
In this article, we’ll explore how long root canal-treated teeth typically last, what factors influence longevity, and how we ensure excellent outcomes at our clinic—open 7 days a week and aligned with the Alberta Dental Association (ADA) Fee Guide.
What Is a Root Canal?
A root canal is a dental procedure used to treat a tooth with infected or damaged pulp (the inner tissue containing nerves and blood vessels). If left untreated, the infection can spread, leading to pain, swelling, and tooth loss.
During a root canal procedure, our dentists:
- Remove the infected or dead pulp
- Clean and disinfect the root canals
- Fill and seal the space with biocompatible material
- Often place a dental crown to protect the tooth
The process is highly effective, and at ProGrace Dentistry, we aim to make it as comfortable as possible by offering sedation options and emergency appointments 7 days a week.
How Long Does a Root Canal Last?
Studies from the American Association of Endodontists show that over 90% of root canal-treated teeth last more than 10 years. With the proper care, many can last 20 years or even a lifetime.
Several factors impact the longevity of your root canal:
1. Timely Placement of a Crown
After a root canal, the tooth is more fragile. Placing a custom crown reinforces the tooth structure, helping prevent fractures and reinfection. Our dentists in NW Calgary often recommend crown placement within a few weeks of the procedure.
2. Tooth Location
Front teeth (incisors and canines) often last longer after root canals because they experience less pressure from chewing. Molars and premolars—used for grinding food—benefit more from immediate crown coverage.
3. Clinical Skill and Technology
At ProGrace Dentistry, we use modern digital imaging and rotary endodontic instruments to ensure the root canal is thoroughly cleaned and sealed. Our dentists have extensive experience treating complex cases and are committed to continuous training to stay current with best practices.
4. Patient Oral Hygiene
Patients who brush twice daily, floss, and maintain regular dental checkups are far more likely to keep their root canal-treated tooth healthy. We provide tailored aftercare instructions and reminders to help you maintain excellent dental hygiene.
5. Avoiding Harmful Habits
If you grind your teeth at night (bruxism) or chew on hard objects like ice, the pressure can crack your treated tooth or crown. We may recommend a custom nightguard to protect your investment.
Can a Root Canal Fail?
Root canal failure is rare but possible. It may occur due to:
- Incomplete removal of infection
- Cracked roots or missed canals
- Reinfection due to poor sealing
- Delayed or missing crown placement
Signs of root canal failure include recurring pain, swelling, and sensitivity. At ProGrace Dentistry, we offer root canal retreatment and CBCT scanning for accurate diagnosis and resolution of failed cases.
