How a Root Canal Treatment Works

Root canal treatment, often referred to as RCT, is a dental procedure aimed at saving a tooth that is severely decayed, infected, or damaged. It involves several key steps to remove the infected pulp and restore the tooth’s health and function.

Procedure Overview

The procedure begins with the dentist administering local anesthesia to numb the area around the affected tooth, ensuring the patient feels comfortable throughout. This is crucial as it allows for a pain-free experience during the treatment.

1. Access and Removal

Once the tooth is numb, the dentist creates a small access hole in the tooth’s crown to reach the infected pulp and root canals. Using specialized instruments, the dentist carefully removes the diseased pulp tissue from inside the tooth and cleans out the infected area thoroughly.

2. Cleaning and Shaping

After the pulp is removed, the dentist cleans and shapes the hollow area inside the tooth and its root canals. This step is crucial to remove any remaining bacteria or debris that could cause further infection.

3. Filling and Sealing

Once cleaned, the dentist fills the root canals to seal them off and prevent bacteria from re-entering. This helps to protect the tooth from future infections.

4. Restoration

Depending on the extent of the damage, a temporary filling may be placed to close the access hole temporarily. In many cases, the tooth will also require a permanent restoration, such as a dental crown, to strengthen and protect it from further damage.


Root canal treatment allows patients to preserve their natural teeth even in cases of severe decay or infection. By removing infected pulp, cleaning the root canals, and sealing the tooth, dentists can alleviate pain and restore functionality, helping patients maintain their oral health and smile confidently.
