Root canal therapy has come a long way in recent years, transforming from a procedure many patients feared into one that is efficient, comfortable, and long-lasting. On The Wonder Tooth Podcast, Dr. Radwa Saad, Princeton cosmetic dentist, sat down with Dr. Nadia Liss, endodontist and founder of Hamilton Endodontics, to discuss the exciting advances in root canal treatment that are changing patient care.

This technology reduces guesswork and ensures patients at Dent Blanche Dental receive the highest standard of dental care.

Traditional hand files were once the standard, but rotary instruments now provide faster and more accurate results.

This means less time in the dental office and a more comfortable experience for patients.

Modern Princeton dentistry also relies on dental microscopes and ultrasonic tools.

These tools significantly improve the success rate of root canal therapy.

This approach not only saves time but also strengthens and protects the treated tooth right away.

Root canals now last longer thanks to improved materials.

With proper dental care, a root canal can last a lifetime.

Many patients still fear root canals, but modern dentistry has made the process far less intimidating.

Faster healing, minimal discomfort, and predictable results help patients feel confident about their dental care.

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.

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.

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.

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.

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.

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.

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.

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.

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.

In this powerful episode of The Wonder Tooth Podcast, Dr. Radwa Saad, DMD sits down with Tricia and Kurt Baker, the founders of the Princeton-based nonprofit Attitudes in Reverse, to discuss a deeply personal and critical issue: the impact of mental health on our children.

The Bakers share their heartbreaking story of how mental illness affected their son and ultimately led to his passing. Out of tragedy, they built a movement—Attitudes in Reverse (AIR)—with the mission of breaking the stigma, increasing awareness, and providing education about mental health, especially among youth.

Mental health does not exist in isolation—it affects every part of our lives, from relationships and academics to physical health and even oral care. Many children and teens suffer in silence due to stigma, lack of awareness, or fear of speaking out. The Bakers emphasize the importance of early intervention, compassionate listening, and open conversations.

On the podcast, Dr. Saad highlights how dentists and other healthcare providers can also play a role in recognizing signs of stress, anxiety, or depression in patients. Something as simple as bruxism (teeth grinding), neglected oral hygiene, or jaw pain can be red flags that a patient is struggling with mental health challenges.

This conversation is especially meaningful as Dr. Saad has been named a 2025 Champion of Hope by Attitudes in Reverse. She will be honored at their upcoming Champion of Hope Gala on October 8, 2025, held at the Marriott Forrestal Village in Princeton, NJ.

This prestigious recognition celebrates community leaders and advocates who are raising awareness, supporting mental health initiatives, and giving hope to individuals and families.

Supporting mental health initiatives is a shared responsibility. Here are a few ways you can take action today:

1. Donate to Attitudes in Reverse → Visit AIR.ngo to contribute directly to their mission.
2. Attend the Champion of Hope Gala → Purchase tickets at toh.ngo/tickets and join an inspiring evening dedicated to awareness and change.
3. Spread Awareness → Share this episode of The Wonder Tooth Podcast with friends, family, or colleagues to help normalize mental health conversations.

This episode is not just about dentistry—it’s about humanity. Dr. Saad, Tricia, and Kurt remind us that mental health is health, and by talking openly about it, we can save lives.

Tune in to this special edition of The Wonder Tooth Podcast to hear the Bakers’ inspiring journey and learn how we can all play a part in creating a more compassionate and understanding community.

In this new episode of the wonder tooth podcast, Dr. Radwa Saad | Cosmetic Dentist & Host of The Wonder Tooth Podcast and founder of Dent Blanche Dental

Tartar, also known as dental calculus, is a hardened form of dental plaque. Plaque is the soft, sticky film that forms on your teeth throughout the day, composed of bacteria, food particles, and saliva. When plaque is not removed regularly, it combines with minerals in your saliva and hardens—usually within 24 to 72 hours—into tartar.

Tartar forms both above and below the gumline, and while plaque can be removed with daily brushing and flossing, tartar cannot. It requires professional dental cleaning to be removed effectively.

Tartar is more than just a cosmetic issue. It creates a rough surface where more plaque can accumulate and causes a cascade of oral health issues, including:

1. Gum Disease (Gingivitis and Periodontitis)
2. Tartar irritates the gums, causing inflammation, bleeding, and infection. If not treated, it can progress to periodontitis, a serious gum disease that can lead to bone loss and tooth loss.
3. Tooth Decay
4. The bacteria in tartar produce acids that erode tooth enamel, leading to cavities.
5. Persistent Bad Breath (Halitosis)
6. Tartar buildup traps bacteria and food particles, which release foul odors.
7. Stained Teeth
8. Tartar is porous and absorbs stains from coffee, tea, wine, and tobacco, making your teeth look yellow or brown.
9. Systemic Health Effects
10. Chronic inflammation in the mouth from tartar-related gum disease is linked to heart disease, diabetes, and stroke.

Tartar tends to accumulate in areas that are harder to clean:

1. Behind the lower front teeth
2. On the outside of upper molars
3. Along the gumline
4. Between crowded teeth
5. Around dental restorations like bridges or crowns

If you notice that your teeth feel rough in these areas or that your gums bleed when brushing, you may have tartar and need a professional cleaning.

The key to preventing tartar is controlling plaque before it hardens. Here’s how you can stay ahead of the curve:

Have you ever opened your mouth wide and noticed a silver glint in the back? Or maybe your dentist asked if you preferred a silver or white filling—and you weren’t sure which to choose? Today on The Wonder Tooth, we’re diving into one of the most debated topics in dentistry: silver amalgam vs. white composite fillings. What are they made of? How do they perform? And do they really affect your body differently? Let's get into the facts, myths, and science behind these two popular dental materials.

Definition:

Silver fillings, or amalgam fillings, have been used in dentistry for over 150 years. They’re made from a mixture of metals, including:

1. Mercury (around 50%)
2. Silver
3. Tin
4. Copper
5. Zinc (sometimes)

The mercury binds the metals together and creates a hard, durable material once set.

1. Durability and Longevity
2. Lasts 10–15 years, sometimes longer.
3. Withstands strong chewing forces, ideal for molars.
4. Cost-Effective
5. Generally more affordable than composite fillings.
6. Quick Placement
7. Less technique-sensitive.
8. Easier to place in areas with limited access or moisture.
9. Bacteriostatic Properties
10. Some studies suggest amalgam fillings may inhibit bacterial growth under the filling.

1. Aesthetic Concerns
2. Very noticeable, especially when laughing or speaking.
3. Not suitable for front teeth or visible areas.
4. Cracks and Fractures
5. Metal expands and contracts with temperature changes, which can lead to tooth fractures over time.
6. May weaken the remaining tooth structure.
7. Mercury Content and Health Concerns
8. Contains elemental mercury, which is toxic in large amounts.
9. The ADA and FDA state that amalgam is safe for most people, but some health-conscious patients and holistic providers prefer to avoid it.
10. Mercury exposure risk is higher during placement or removal—not while intact.

You can brush, floss, and rinse all you want—but if your diet isn’t right, your smile may still suffer.

Learn how your everyday diet affects your teeth and gums. Dr. Radwa Saad shares surprising facts, common food mistakes, and top smile-friendly choices.

Many people don’t realize their eating habits are slowly wearing down their enamel, inflaming their gums, and feeding harmful bacteria—all without them even knowing.

Here are the top dietary truths every smile-conscious person should know:

6 “Healthy” Habits That Secretly Harm Your Teeth

1. Lemon Water All Day – Acidic and erosive. Drink it fast, not over hours. Use a straw.

2. Dried Fruits & Trail Mix – Sticky and sugary. Feed cavity-causing bacteria.

3. Smoothies – High in natural sugars and acids. Drink quickly and rinse after.

4. Coffee with Sugar or Milk – Sipping constantly erodes enamel and stains teeth.

5. Keto or High-Protein Diets– Can cause dry mouth and “keto breath.” Stay hydrated.

6. Chewing Ice – Leads to microfractures and sensitivity.

Smile-Boosting Foods to Add

- Cheese & Yogurt – Strengthen enamel with calcium and casein

- Crunchy Veggies – Scrub teeth naturally, stimulate saliva

- Green Tea – Reduces inflammation, fights bacteria

- Strawberries – Natural brighteners, high in vitamin C

- Nuts & Seeds– Good fats and minerals

- Mineral-Rich Water – Supports tooth structure, unlike distilled water

3 Pro Tips for a Smile-Smart Diet

1. Time Your Eating – Avoid all-day grazing. Let saliva restore balance.

2. Wait Before Brushing After Acidic Foods – Rinse first, then brush after 30 mins.

3. Watch for Tongue Clues – Burning, coating, or soreness might be nutrition-related.

Final Thought

Your mouth is a reflection of your diet. Choosing the right foods—and eating them the right way—can strengthen, whiten, and protect your smile long-term.
