Yes, a root canal can last a long time, if not a lifetime, under the right aftercare. However, its durability depends on three important factors: the quality of the root canal treatment performed, the quality of the restoration on the tooth after treatment, and how to protect it.
Let’s break it down so we know what we can expect and how to get the maximum longevity from the results of our root canal therapy.
How Does a Root Canal Work?
- A root canal is done to remove the infected tissue from the inner part of the tooth.
- The inner part of the tooth is cleaned and sealed.
- A crown is typically placed to protect the tooth.
Root canals relieve pain, prevent or treat further infection, and enable you to keep your natural tooth.
Why Should You Consult a Dentist?
Choosing the right provider matters. A skilled dentist in Downtown Calgary will make sure the root canal is done properly and that the tooth is fully sealed and protected.
What to expect from a trusted clinic:
- Use of modern tools and digital imaging
- Gentle technique and thorough cleaning
- Strong crown placement to seal the tooth
- Aftercare tips to support healing
When done right, a root canal can give you decades of comfort.
Can a Root Canal Last a Lifetime?
In some scenarios, yes. If the tooth was treated very early, sealed well and protected from further damage, you may never need to have the tooth retreated.
Factors that help it last:
- Getting a crown immediately after the root canal
- Avoiding hard or sticky foods
- Daily brushing and flossing
- Seeing a dentist every six to twelve months for checkups
Teeth without a crown are much more likely to fracture or fail than teeth that have been crowned.
What Affects the Durability of Root Canal Treatment?
The durability of a root canal depends on both the quality of the treatment and how the patient cares for the tooth. A well-done root canal, followed by a properly placed crown, can last 10–20 years or more.
Tips to increase durability:
- Do not chew on hard things with the treated tooth.
- In the event that you grind your teeth, wear a sleep guard.
- Treat minor problems as soon as possible.
Even with great care, no treatment is 100% permanent, but root canals are among the most durable dental procedures.
What Is the Average Root Canal Lifespan?
The root canal lifespan varies from person to person. On average, a root canal-treated tooth lasts around 10 to 15 years. With good oral hygiene and regular checkups, many people enjoy longer results.
What affects lifespan:
- Type of tooth (molars may wear out sooner)
- Condition of the surrounding bone and gum
- Patient habits (biting ice, poor brushing, etc.)
- Quality of the filling and crown
If a root canal fails, retreatment or a dental implant may be needed.
