What Happens During a Root Canal? – A Complete Patient Guide
A root canal treatment is one of the most common and effective dental procedures used to save a damaged or infected tooth. Many people feel anxious when they hear the words “root canal,” but modern dentistry has made the procedure safe, painless, and highly successful. This blog explains everything you need to know about what happens during a root canal and why it is important for your oral health.
What Is a Root Canal?
Inside every tooth is a soft tissue called the pulp, which contains nerves, blood vessels, and connective tissue. When this pulp becomes infected due to deep decay, repeated dental procedures, cracks, or trauma, it can cause severe pain and swelling. A root canal treatment removes this infected pulp, cleans the tooth from inside, and seals it to prevent further infection.
When Do You Need a Root Canal?
You may need a root canal if you experience:
Persistent tooth pain
Sensitivity to hot or cold that lasts long
Swollen or tender gums
Darkening of the tooth
Pus or abscess near the tooth
Ignoring these symptoms can lead to worsening infection and possible tooth loss.
Step-by-Step: What Happens During a Root Canal?
1. Examination and X-rays
The dentist first examines your tooth and takes an X-ray to assess the extent of infection and the shape of the root canals.
2. Local Anesthesia
Local anesthesia is given to numb the area around the tooth. This ensures the procedure is comfortable and painless.
3. Opening the Tooth
A small opening is made on the chewing surface of the tooth to access the infected pulp inside.
4. Removal of Infected Pulp
The damaged pulp, nerves, and bacteria are carefully removed from the root canals using specialized instruments.
5. Cleaning and Disinfection
The canals are thoroughly cleaned, shaped, and disinfected to remove any remaining bacteria and reduce the risk of reinfection.
6. Filling and Sealing
The cleaned canals are filled with a biocompatible material (usually gutta-percha) and sealed tightly to protect the tooth.
7. Tooth Restoration
A temporary or permanent filling is placed. In most cases, a dental crown is recommended to restore strength, function, and appearance.
Is Root Canal Treatment Painful?
No. With modern anesthesia and techniques, a root canal is usually no more uncomfortable than getting a regular filling. In fact, the procedure relieves the pain caused by infection.
What to Expect After the Treatment?
Mild soreness for a few days is normal
Avoid chewing hard foods on the treated tooth until fully restored
Maintain good oral hygiene
Follow up for crown placement if advised
With proper care, a root canal–treated tooth can last a lifetime.
