Root Canal Therapy

Root canal therapy becomes necessary when the nerve of a tooth is affected by decay or infection. The purpose of this treatment is to save the tooth by removing the infected or decayed pulp, nerves, bacteria, and any damaged tissue inside the tooth. The resulting space is then filled with special dental materials to restore the tooth’s function and integrity.

Choosing root canal therapy offers the best chance of preserving a tooth that would otherwise require extraction. While some patients may consider tooth extraction as a solution, it’s important to understand that removing a tooth can lead to more complex and costly issues, as well as potential problems with neighboring teeth.

Root canal treatment has a high success rate and can provide long-term benefits, often lasting a lifetime. However, in rare cases, a tooth may require retreatment if new infections develop.

Signs and symptoms that may indicate the need for root canal therapy include:

• Presence of an abscess or pimple on the gums.
• Sensitivity to hot and cold temperatures.
• Severe toothache pain.
• Sometimes, no noticeable symptoms are present.
• Swelling and/or tenderness.

Common reasons for undergoing root canal therapy are:

• Decay that has reached the tooth pulp.
• Infection or abscess formation within the tooth or at the root tip.
• Injury or trauma to the tooth.

The root canal procedure typically involves one or more appointments and can be performed by a general dentist or an endodontist (a root canal specialist).

During the procedure, the tooth will be numbed to ensure your comfort. A rubber dam will be placed around the tooth to isolate it and keep it dry. An access opening will be made on the top of the tooth, allowing specialized root canal files to remove the pulp, nerve tissue, bacteria, and any decay. If there is decay, it will be carefully removed with dental instruments designed for that purpose.

Once the tooth is thoroughly cleaned and disinfected, it will be sealed with either a permanent filling or a temporary filling, depending on the need for additional appointments.

At the next appointment, usually scheduled for the following week, the roots and the inside cavity of the tooth will be filled and sealed with special dental materials. A filling will be placed to cover the access opening. Additionally, it is recommended that teeth receiving root canal treatment be protected with a crown (cap) to strengthen and safeguard the tooth, restoring its full function.

After the treatment, you may experience some sensitivity, but it will gradually subside as the inflammation diminishes and the tooth heals.

Your dentist will provide you with specific care instructions after each appointment. Maintaining good oral hygiene practices and scheduling regular dental visits will help ensure the long-term success of your root canal treatment.
