If you’re experiencing tooth pain or sensitivity, a root canal treatment could help. This standard procedure treats infections inside a tooth by removing infected or inflamed pulp while keeping the tooth intact. An endodontist or dentist carefully cleans and reshapes the inside of the tooth to remove harmful bacteria. After that, the tooth is filled with a safe material and sealed to prevent reinfection.
The main goal is to save the tooth so it stays functional instead of being pulled out. This treatment helps ease pain, improve oral health, and prevent infection from spreading to other teeth and gums. At Leslie North Dental, we ensure that your root canal is comfortable and practical.

Concern | What You Need to Know |
Why do I have severe tooth pain? | It could be because of an infection deep inside your tooth, affecting the pulp. If left untreated, it may lead to more serious complications. |
Can my tooth be saved instead of removed? | Yes! A root canal removes the infection while preserving your natural tooth, preventing unnecessary extractions. |
Will the procedure be painful? | Not at all! You’ll feel a slight discomfort with modern anesthesia and pain management techniques during the treatment. |
What happens during a root canal? | The dentist removes infected pulp, cleans and disinfects the tooth, then fills and seals it to prevent reinfection. A crown may be added for strength. |
How do I know if I need a root canal? | Persistent pain, sensitivity to hot or cold, swollen gums, darkened tooth color, and pimple-like swelling on the gums are common signs. |
Is a root canal a long-term solution? | Absolutely! A well-treated tooth can last a lifetime with proper oral care and routine dental check-ups. |
Why is Root Canal Treatment Needed?
A root canal is needed when the tooth’s pulp gets infected, often due to tooth decay, injury, or multiple dental treatments. If not treated, the infection can spread, causing intense pain and possibly leading to tooth loss. Signs that you might need a root canal include:
- Persistent tooth pain
- Sensitivity to hot or cold
- Swollen gums
- Darkening of the tooth

The Root Canal Procedure Step-by-Step
Root canal treatment is a step-by-step procedure to remove infection and restore the tooth’s function. It usually includes cleaning the damaged pulp, sterilizing the area, filling the canals, and sealing the tooth to avoid future problems. The treatment is done under local anesthesia, so patients feel minimal discomfort. Here’s a breakdown of each step in the process:
1. Diagnosis and X-rays
Your dentist will begin by taking X-rays to check the damage and determine if a root canal treatment is needed. The X-rays help show the severity of the infection and allow the dentist to plan the procedure correctly. Catching the problem early can prevent complications and improve the chances of a successful treatment.
2. Anesthesia and Pain Management
Before starting the procedure, local anesthesia is used to numb the area, ensuring you feel no pain. Thanks to modern techniques, pain relief is very effective. While you may feel pressure during the procedure, intense pain is unlikely. Afterward, discomfort is usually mild and can be managed with painkiller medication.

3. Cleaning and Shaping the Root Canal
The infected pulp is carefully removed, and the inside of the tooth is cleaned and shaped. This helps get rid of bacteria and prevents the infection from spreading. Special tools are used to ensure the canals are correctly shaped and ready for filling.
4. Sealing and Restoration
After cleaning, the space is filled with a safe material and sealed. Depending on the tooth’s condition, a dental crown might be added to restore strength and function. As Bill, one of our patients, once said: “Restoration isn’t just about fixing what’s broken; it’s about bringing back strength and purpose.”
