What is the point of a root canal?

A root canal is a dental procedure used to treat a severely damaged or infected tooth. The goal of a root canal is to remove the infected or damaged pulp, relieve pain, prevent the spread of infection, and save the tooth.

The pulp is the soft tissue inside the tooth that contains nerves, blood vessels, and connective tissue. When the pulp becomes damaged or infected, it can lead to several dental problems, such as:

- Severe tooth pain

- Sensitivity to hot or cold temperatures

- Swelling and tenderness in the gums

- A persistent or recurring pimple on the gums

- Discoloration of the affected tooth

A root canal involves several steps:

1. Diagnosis: The dentist examines the tooth and performs tests, such as X-rays, to determine the extent of the damage or infection.

2. Anesthesia: Local anesthesia is used to numb the area around the affected tooth, ensuring that the procedure is pain-free.

3. Accessing the pulp: The dentist creates a small access hole in the tooth's surface to reach the pulp chamber.

4. Removing the pulp: Specialized dental instruments are used to remove the infected or damaged pulp from the pulp chamber and root canals.

5. Cleaning and shaping: The dentist thoroughly cleans the pulp chamber and root canals, removing any remaining debris or bacteria. The canals are shaped to prepare them for filling.

6. Filling: The cleaned and shaped canals are filled with a biocompatible material called gutta-percha to seal them and prevent future infection.

7. Restoring the tooth: In most cases, a crown or filling is placed over the treated tooth to restore its strength and function. This step is crucial for long-term protection of the tooth.

A root canal is a successful treatment option that can alleviate pain, preserve the natural tooth, and prevent the spread of infection. Regular dental check-ups and good oral hygiene practices can help prevent the need for root canal treatment.
