Is Tooth Dead After Root Canal? The Myth and the Reality

What is a Root Canal?

A root canal is a dental procedure that involves removing the infected or inflamed pulp from inside a tooth. The pulp is the soft tissue that contains nerves, blood vessels, and connective tissue that nourish the tooth. When the pulp is damaged by decay, trauma, or infection, it can cause severe pain and sensitivity. A root canal aims to relieve the pain and save the tooth from extraction.

During a root canal, the dentist makes a small opening in the crown of the tooth and uses special instruments to clean out the pulp chamber and the root canals. The dentist then fills and seals the empty space with a rubber-like material called gutta-percha. Finally, the dentist restores the tooth with a filling or a crown to protect it from further damage.

Is the Tooth Dead After a Root Canal?

One of the common misconceptions about root canal treatment is that the tooth becomes dead after the procedure. This is not true. The tooth is still alive and functional, even though the pulp has been removed. The tooth can still receive nutrients and oxygen from the surrounding tissues and the periodontal ligament, which attaches the tooth to the jawbone. The tooth can also still sense pressure and temperature, although not as sensitively as before.

The reason why some people think that the tooth is dead after a root canal is because the tooth no longer has nerves that transmit pain signals to the brain. This means that the tooth will not feel any pain or discomfort from the infection or inflammation that caused the need for a root canal. However, this does not mean that the tooth is dead or useless. On the contrary, the tooth can still perform its normal functions of chewing and biting, as well as supporting the adjacent teeth and maintaining the alignment of the bite.

What are the Benefits of a Root Canal?

A root canal is a beneficial treatment that can save a tooth from extraction and prevent further complications. Some of the benefits of a root canal are:

  • It eliminates the pain and discomfort caused by the pulp infection or inflammation.
  • It preserves the natural tooth structure and appearance, which can improve the aesthetics and self-confidence of the patient.
  • It prevents the spread of the infection to the surrounding tissues, such as the bone, the gums, and the other teeth.
  • It avoids the need for more complex and costly treatments, such as tooth replacement with implants, bridges, or dentures.
  • It restores the function and health of the tooth, allowing the patient to eat, speak, and smile normally.

How to Care for a Tooth After a Root Canal?

A tooth that has undergone a root canal treatment can last for a long time, as long as it is properly cared for. Some of the tips for caring for a tooth after a root canal are:

  • Follow the dentist’s instructions and take the prescribed medications to prevent infection and reduce inflammation.
  • Avoid chewing or biting on the treated tooth until it is fully restored with a filling or a crown.
  • Brush and floss the teeth regularly and gently, paying special attention to the treated tooth and the surrounding area.
  • Visit the dentist regularly for check-ups and cleanings, and report any signs of problems, such as pain, swelling, or sensitivity.
  • Maintain a healthy diet and lifestyle, and avoid habits that can damage the teeth, such as smoking, grinding, or clenching.

A root canal is a safe and effective treatment that can save a tooth from extraction and improve the quality of life of the patient. A tooth that has undergone a root canal is not dead, but alive and functional. With proper care and maintenance, a root canal treated tooth can last for a lifetime.
