Therefore, teeth can die.
Root canal therapy (endodontics) can reclaim teeth after they have died.
In order to understand this, you must first understand the anatomy of a tooth.
The most common causes of pulp death are physical trauma to the tooth, a cracked tooth, or a deep cavity.
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.
What happens when a tooth root dies?
When the nerves in the pulp of the tooth, which is the inner layer, become damaged, such as by injury or decay, they can stop providing blood to the tooth. That can cause an infection and cause the nerve to die. This is also sometimes known as a non-vital tooth.
How long does a tooth last after a root canal?
With proper care, even teeth that have had root canal treatment can last a lifetime. But sometimes, a tooth that has been treated doesn’t heal properly and can become painful or diseased months or even years after treatment.
