According to some studies, root canal treatment has a high success rate and can last for many years, even a lifetime. One of the most detailed studies on the subject examined the long-term effectiveness of 487,476 root canal treatments. According to this report, 98 percent of root canals last one year, 92 percent last five years, and 86 percent last ten years or longer .

Another study found that teeth that receive a root canal and then a filling and crown last about 20 years . A crown is a cap that covers and protects your tooth after a root canal. A crown can strengthen your tooth and improve its appearance.

However, some root canals may fail or need to be redone. This can happen for various reasons, such as:

• The restoration begins to leak
• Poor oral or dental hygiene
• Breakdown of the tooth or sealing material over time
• Presence of an extra canal in the tooth that was missed during the treatment
• An obstruction such as a curved root canal that prevented complete cleaning of the canal
• Vertical cracks in the tooth

• Tooth pain that doesn't go away or comes back after some time
• Sensitivity to heat and cold
• Swollen gums or jaw
• Pimple or boil on the gums
• Tooth discoloration
• Pain when pressure is applied
• Loose tooth

If you notice any of these symptoms, you should contact your dentist or endodontist as soon as possible. An endodontist is a dentist who specializes in root canal treatment. They can evaluate your tooth and determine if you need a retreatment or another option.
