95 What is a Root Canal?

A root canal is one of the most common yet misunderstood dental treatments.

In this episode of The Wonder Tooth Podcast, Dr. Radwa Saad, a leading cosmetic dentist sits with Dr. Nadia Liss, Endodontist in New Jersey.

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.

Modern Dentistry, Comfortable Care

Thanks to advancements in cosmetic dentistry and digital tools, root canal therapy is now quick, efficient, and stress-free. Princeton dentists like Dr. Saad and Dr. Liss use the latest technology to ensure precision and comfort, making the experience much easier than patients expect.

Why Preserving Teeth Matters

Saving your natural dent is always better than extraction. A root canal prevents shifting, bone loss, and the need for costly dental implants. Choosing the best dentist for your care ensures long-lasting results and confidence in your smile.

Root Canal FAQs

Does a root canal hurt?

No, modern root canal treatment is virtually painless. At Dent Blanche Dental in Princeton, we use advanced anesthesia and digital dentistry tools to ensure maximum comfort. Most patients say the procedure feels no different than getting a regular filling.

How long does a root canal take?

A typical root canal procedure usually takes 60 to 90 minutes, depending on the complexity of the tooth. Thanks to rotary instruments and digital imaging, Princeton dentists can often complete treatment in just one visit.

How long does a root canal last?

With proper dental care, a root canal can last a lifetime. After the procedure, most teeth are restored with a porcelain crown, which protects the tooth and ensures long-term strength and function.
