You finally got that root canal done, no more throbbing pain, no more avoiding your favourite foods. But now you’re wondering, how long will it last? With the right care, a root canal-treated tooth can last up to 10—20 years. But things like oral hygiene, the tooth’s location, and whether it’s properly restored all play a role in its longevity.
Regular dental checkups and cleanings at Grand West Dental help keep your treated tooth healthy and free of complications. If you’ve had a root canal and are experiencing discomfort, your dentist can assess whether the tooth needs further attention.
What Is a Root Canal & Why Is It Needed?
To understand how long a root canal can last, it’s helpful to first know what the procedure involves. A root canal is a dental treatment aimed at saving your natural tooth when the pulp (the soft tissue inside the tooth) becomes infected or inflamed. The pulp can become damaged due to several things, including:
- Deep decay or a severe cavity
- Cracked or chipped teeth
- Injury to the tooth (even if there’s no visible damage)
During the procedure, your dentist removes the infected or damaged pulp, cleans and disinfects the root canals, fills them with a durable material, and seals the tooth to prevent future infection. Often, a crown is placed afterward to restore strength and functionality.
A root canal allows you to keep a tooth that might otherwise need to be extracted, preserving your natural bite and preventing the surrounding teeth from shifting.
How Long Can a Root Canal Last?
On average, a root canal can last 10—20 years or longer with proper care. Some patients report that their treated tooth remains problem-free for decades. However, the longevity of the procedure varies depending on individual circumstances.
When treated by an experienced dentist using advanced techniques, and when combined with good oral hygiene, a root canal can provide lasting protection for your tooth.
What Can Affect the Longevity of a Root Canal?
Although root canals are highly effective, their longevity can depend on several key factors:
1. The Extent of Damage to the Tooth
If the tooth was severely decayed or fractured before the root canal, it may require a crown or additional reinforcement to maintain its structure over time.
2. Quality of the Dental Work
The skill of the dentist performing the root canal plays a crucial role in its success. An improperly cleaned or sealed tooth can lead to recurrent infection and shorten the lifespan of the treatment.
3. Placement of the Treated Tooth
Teeth at the back of the mouth (molars) are exposed to more pressure from chewing and grinding than front teeth, which means they may wear down or crack more easily.
4. Oral Hygiene Habits
Good oral hygiene practices, like brushing twice a day, flossing daily, and regular dental check-ups, are essential in protecting the treated tooth and surrounding teeth.
5. Additional Dental Issues
Grinding your teeth (bruxism), gum disease, or other ongoing dental problems can put additional strain on a tooth treated with a root canal and affect its longevity.
Signs You May Need a Retreatment
Root canals are designed to last, but complications can occur in some cases. A retreatment is a dental procedure performed when a tooth that has previously undergone a root canal treatment experiences issues or fails to heal properly. During a retreatment, the dentist or endodontist reopens the affected tooth to remove the original filling material.
The tooth is then carefully cleaned, disinfected, and re-sealed to address any persistent infection or structural issues. Here are signs that you may require retreatment or further dental care:
- Persistent pain or sensitivity in the treated tooth
- Swelling or tenderness around the tooth or gums
- A recurring abscess (pimple-like swelling) on the gum
- Cracking or damage to the crown or tooth structure
Tips for Making Your Root Canal Last Longer
1. Maintain Excellent Oral Hygiene
- Brush your teeth for 2 minutes, twice a day, using fluoride toothpaste.
- Floss daily to remove food particles and plaque from between teeth and the gumline.
2. Replace the Crown When Necessary
The crown placed over the treated tooth can wear out over time. Regularly visiting your dentist will help identify when it’s time for a replacement.
3. Address Bruxism
If you grind your teeth at night, talk to your dentist about wearing a custom night guard to protect the treated tooth.
4. Go for Regular Dental Check-Ups
Routine visits allow your dentist to monitor the treated tooth and catch any developing problems early. Check-ups play a key role in maintaining long-term oral health.
5. Avoid Using Your Teeth as Tools
Refrain from biting your nails, opening packages with your teeth, or eating extremely hard foods that can cause damage to a treated tooth.
When to See Your Dentist for Follow-Up Care
A successful root canal is the result of teamwork between you and your dentist. After the procedure, your dentist will guide you on when to come in for follow-ups. Make sure to stick to these appointments, even if the tooth feels fine.
