1. What Is Baking Soda Toothpaste?

Baking soda toothpaste contains sodium bicarbonate, a mild alkaline compound that’s been used in oral care for generations. It’s one of the simplest and most effective natural ingredients for cleaning teeth, removing stains, and neutralizing acids in the mouth.

And despite its humble reputation, baking soda is clinically proven to benefit oral health when formulated correctly, like our baking soda toothpaste here at TranscenDental.

2. The Science Behind Baking Soda and Oral Health

Baking soda’s chemical structure allows it to:

• Act as a gentle abrasive, polishing surface stains

• Neutralize acids in the mouth, protecting enamel from erosion

• Reduce plaque formation by limiting acid-loving bacteria

• Improve breath by absorbing volatile sulfur compounds (VSCs)

A 3 month Randomized Controlled Trial found that:

“Consistently outperformed non-baking soda formulations in plaque removal and gingival health.”

3. How Baking Soda Whitens Your Teeth

Baking soda whitens teeth by physically polishing surface stains. It doesn’t bleach like peroxide—it’s a mechanical stain remover, lifting tannins from coffee, wine, tea, and food pigments.

In trials, brushing with baking soda toothpaste for 2–4 weeks consistently results in 1–2 shades of visible whitening, especially when combined with silica or mild enzymes like papain or bromelain.

Unlike harsh commercial whiteners, baking soda works gradually and safely. Think of it as resetting your teeth to their natural brilliance, rather than artificially bleaching them.

4. Is Baking Soda Toothpaste Safe for Enamel?

Yes—if formulated correctly.

Baking soda has a low Relative Dentin Abrasivity (RDA) score, typically around 7, making it one of the gentlest abrasives in oral care.

Compare that to:

• Charcoal: RDA often 100–300+

• Whitening toothpaste with silica: RDA 120–150

• ADA upper safety limit: 250

This means baking soda:

• Polishes without scratching enamel

• Reduces risk of sensitivity

• Can be used daily, even for people with gum recession or thin enamel

5. Baking Soda vs. Other Whitening Agents

While peroxide gives faster results, baking soda is a gentle, long-term option that’s safe for sensitive mouths and young teeth.

6. Baking Soda’s Role in Balancing Oral pH

Baking soda is highly alkaline (pH ≈ 8.3). This matters because:

• Most oral pathogens (like S. mutans) thrive in acidic environments

• After we eat, the pH in our mouth drops—especially with carbs and sugar

• Baking soda quickly restores neutral-to-alkaline conditions, minimizing acid erosion

Maintaining a healthy pH helps:

• Prevent enamel loss

• Reduce sensitivity

• Discourage harmful bacterial overgrowth

This is why baking soda is particularly useful in a fluoride-free or microbiome-supportive toothpaste.

7. Does Baking Soda Kill Bad Breath?

Yes. Baking soda helps neutralize volatile sulfur compounds (VSCs) like hydrogen sulfide, which are produced by bacteria on the tongue and between teeth.

Its mild antibacterial effect, combined with odor absorption, makes it excellent for:

• Morning breath

• Post-coffee breath

• Breath issues related to acidic or sugary diets

8. TranscenDental’s Use of Baking Soda: Smart, Gentle, Balanced

We include baking soda in TranscenDental Mouthpaste for three key reasons:

1. pH Buffering – It helps keep the mouth alkaline, supporting remineralization

2. Mild Polishing – Gently lifts stains without scratching enamel

3. Odor Neutralizing – Binds odor compounds for fresher breath

But here’s the difference: we don’t rely on baking soda alone.

We pair it with:

• 15% nano-hydroxyapatite to actively restore enamel

• Xylitol to inhibit plaque bacteria

• Botanicals for tissue healing

• Silica and clays for low-abrasion polishing

• Ocean trace minerals to nourish teeth and gums

Together, these create a synergistic effect that amplifies the benefits of baking soda—without relying solely on it for results. Baking soda alone is not enough to do the trick, it has a ton of great benefits but it is really the precise combination of ingredients we have found to have these profound benefits.

9. Baking Soda and the Oral Microbiome

Unlike harsh antimicrobials that wipe out your oral flora, baking soda:

• Doesn’t kill good bacteria

• Helps shift the environment so bad bacteria can’t thrive

• Supports a resilient, self-cleaning oral ecosystem

This aligns perfectly with our philosophy at TranscenDental: the goal isn’t to sterilize your mouth—it’s to restore balance.

10. Who Should Use Baking Soda Toothpaste?

✅ If you want a natural whitening boost
✅ If you have acidic saliva or frequent cavities
✅ If you want to strengthen enamel without fluoride
✅ If you have sensitive teeth or receding gums
✅ If you want a gentle, safe daily toothpaste

It's especially effective when paired with remineralizing and microbiome-friendly ingredients—like the ones in our formula.

11. Frequently Asked Questions

Q: Can I brush with pure baking soda?
A: Not recommended long-term. It lacks essential ingredients like remineralizers and can become overly abrasive in raw form. Use it in a balanced toothpaste formula.

Q: Is baking soda toothpaste safe for kids?
A: Yes—when properly formulated, it's gentle and non-toxic. Ours contains only food-grade ingredients and is safe for the whole family.

Q: Does baking soda kill bacteria?
A: It has a mild antibacterial effect, mostly through pH modulation. It supports a healthier oral environment without wiping out your microbiome.

Q: How fast does it whiten?
A: Expect subtle results over 2–4 weeks—1–2 shades. It's gentle and gradual, not dramatic like peroxide.

Q: Does baking soda damage fillings or dental work?
A: Not when used in a balanced toothpaste with low RDA. Our formula is safe for dental work, veneers, and composites.

12. Final Thoughts

Baking soda toothpaste is more than a DIY hack—it’s a scientifically backed, enamel-safe, microbiome-friendly way to brighten your smile, freshen your breath, and protect your mouth naturally.

At TranscenDental, we use baking soda in harmony with:

• 15% nano-hydroxyapatite for enamel repair
