How long does a root canal last?
Root canals are over 95% successful and can last a lifetime. The most important thing to do to make a root canal last as long as possible is get the permanent restoration (fillings or crowns) on the tooth immediately following the root canal and maintain that restoration with impeccable hygiene.
What are symptoms of a failed root canal?
Root Canal Failure Symptoms
Signs and symptoms of failed root canal therapy include sensitivity to cold or hot, swelling, and/or pain from chewing.
Can a root canal be redone?
Yes, root canals can be redone or “retreated”. If a tooth becomes re-contaminated any time after the initial root canal, there may be a need for retreatment. Occasionally, there are accessory canals or variations in tooth anatomy that prevent the initial root canal from being successful.
Do root canals cause health problems?
Root canal therapy is not the cause of cancer or heart attacks. Root canals do not leave areas of necrotic bone in your jaw that are filled with bacteria and lead to chronic inflammation and illness.8 Feb 2019
