Root Canal Therapy Explained with Dr. Nadia Liss, Endodontist

At Dent Blanche Dental, we believe patient education is the foundation of exceptional dental care. In this special episode of The Wonder Tooth Podcast, Dr. Radwa Saad sits down with Dr. Nadia Liss, endodontist and founder of Hamilton Endodontics, to explain what a root canal is, why it is performed, and how modern Princeton dentistry has made the procedure more comfortable than ever.

What Is a Root Canal?

A root canal is a common dental treatment designed to remove infection inside the tooth and preserve your natural smile. Instead of extracting the tooth, your Princeton dentist carefully removes damaged pulp, disinfects the area, and seals the tooth to restore its health. This approach is essential for saving natural teeth and avoiding the long-term issues that follow tooth loss.

When Do You Need a Root Canal?

If you are experiencing:

1. Persistent toothache
2. Sensitivity to hot or cold
3. Swelling or tenderness around the gums
4. A dental abscess

…it may be time to visit a Princeton dental office for evaluation. Dr. Nadia Liss explains that these symptoms should never be ignored, as early treatment provides the best outcome.

Step-by-Step Treatment Overview

During the podcast, Dr. Liss provides a simple breakdown of the root canal process:

1. Diagnosis – Using digital imaging to pinpoint infection.
2. Anesthesia – Ensuring the treatment is completely painless.
3. Cleaning – Removing infected tissue from inside the tooth.
4. Sealing – Restoring the tooth’s structure with advanced materials.
5. Restoration – Often finished with a crown to protect and strengthen the tooth.
