any people looking for a brighter smile wonder: is it harmful to brush teeth with baking soda?
Baking soda, also known as sodium bicarbonate, has been used in oral care for generations to whiten your teeth.
Its natural whitening properties and mild abrasive texture help lift surface stains and freshen breath. But while brushing teeth with baking soda has its perks, it’s not without possible drawbacks.
Let’s break down both sides so you can decide if this natural option belongs in your routine.
Why People Use Baking Soda for Brushing
For many, baking soda for brushing is appealing because it feels simple, natural, and affordable. Research also supports some clear advantages:
-
Whitens gently: The mild abrasive action of baking soda helps remove surface stains, giving teeth a brighter appearance without the harshness of stronger abrasives. This is why many whitening brands highlight its natural whitening properties.
-
Supports gum health: Clinical studies show baking soda toothpastes improve plaque and gingivitis outcomes. For example, NX West (2025) found that a sodium bicarbonate toothpaste used twice daily significantly improved oral health compared to one without it.
-
Controls plaque: Jose et al. (2018) demonstrated that high-baking soda fluoride toothpaste disrupted plaque biofilms more effectively than regular fluoride toothpaste, improving cleaning and reducing oral bacteria.
-
Balances acids: Because baking soda neutralizes mouth acids, it creates an environment less friendly to cavity-causing bacteria and helps protect tooth enamel.
-
Affordable and accessible: Compared to costly whitening gels, strips, or in-office treatments, a box of baking soda is inexpensive and widely available.
These are the core benefits of baking soda in oral care, which is why so many people choose to whiten teeth with baking soda as part of their at-home routine.
What to Watch Out For
Of course, not everything about using baking soda is positive. Dental experts warn about important limitations when it comes to long-term oral health:
-
Enamel wear is possible: While baking soda is safe when used in moderation, overdoing it can make teeth more vulnerable. Some whitening pastes increase enamel and dentin roughness, showing that abrasivity is a real concern. Brushing too hard or too often with abrasive ingredients may thin enamel and lead to sensitivity.
-
No fluoride protection: Baking soda lacks fluoride, which means it cannot strengthen enamel or provide essential cavity protection. A 2017 study emphasized that fluoride toothpaste remains key for preventing decay, even if baking soda alone can help clean.
-
Gum irritation: Aggressive brushing with baking soda may irritate the gums, especially if the paste is gritty. People with existing sensitivity need to be cautious.
-
Not ideal for dental work: Crowns, veneers, or braces may react differently to abrasives. Dental professionals recommend caution for patients with restorations.
-
Overuse risks: A review by de Freitas et al. (2021) showed that frequent use of abrasive whitening products can cause soda damage in the form of enamel changes or irritation of the gums.
So while teeth with baking soda can look whiter, there are reasons to avoid using baking soda alone as your main toothpaste.
Baking Soda vs Commercial Toothpaste
This is where many people get stuck: should you rely on baking soda alone, or stick with commercial toothpaste?
-
Commercial formulations are safer for daily use: They balance cleaning power with lower abrasivity. Baking soda plus fluoride toothpaste reduced plaque buildup more effectively than traditional pastes.
-
Fluoride is essential: Unlike baking soda alone, commercial options protect against tooth decay, remineralize enamel, and provide long-term oral health benefits.
-
Better-rounded formulas: Many whitening toothpaste brands pair baking soda and water with other active ingredients like hydrogen peroxide for stain lifting, or flavoring agents like peppermint oil for freshness.
-
Convenience and taste: While you can brush your teeth with a homemade baking soda paste, a ready-made tube makes it easier to stay consistent and more pleasant.
Put simply, while teeth with baking soda can benefit, commercial products with fluoride toothpaste and sodium bicarbonate provide the safest and most effective balance for everyday use.
Ready-to-Go Baking Soda Toothpastes
Instead of mixing baking soda and water at home, many people prefer commercial toothpastes with the right balance of baking soda and fluoride.
-
Balanced protection: These pastes contain fluoride for cavity defense while keeping the whitening benefits of baking soda. This solves the issue of using baking soda alone, which leaves your teeth without protection.
-
Improved cleaning: Formulations with higher baking soda levels can significantly disrupt plaque biofilms.
-
Better experience: Brands often add mint flavors like peppermint oil and smoother textures, making it more pleasant to brush your teeth daily.
-
Trusted by experts: The American Dental Association advises choosing products with their Seal of Acceptance, which guarantees they are safe and effective.
How to Use Baking Soda Safely
If you’re trying brushing with baking soda, stick to these evidence-based guidelines:
-
Limit home mixes: If you mix it yourself, use equal parts baking soda and water, then brush gently once or twice weekly. Don’t leave it on for more than a minute to avoid wear.
-
Prioritize fluoride: Use a fluoride toothpaste every day. Baking soda is helpful but doesn’t replace fluoride’s protective role.
-
Be cautious with sensitivity: People with sensitive teeth or gum disease should consult a dentist first.
-
Avoid harmful combos: Never mix with acidic liquids like lemon juice or vinegar. These accelerate erosion and can cause tooth decay.

Alternatives Beyond Baking Soda
If your goal is whitening, there are several other approaches you can use alongside or instead of baking soda. Each option comes with its own pros and cons, so it’s always a good idea to understand how they work before making changes to your routine.
-
Whitening toothpastes with hydrogen peroxide: These formulas are designed to remove stains more effectively than baking soda alone. By reaching deeper discoloration within the enamel, they offer more noticeable results while still protecting with fluoride.
-
Over-the-counter whitening strips and gels: These products rely on peroxide-based agents that can whiten teeth several shades. They are convenient to use at home but may cause short-term sensitivity or bad breath if overused.
-
Professional cleanings and whitening: When stains are severe, you may need professional help. Dentists provide reliable results and can tailor treatments to protect your enamel while lifting discoloration.
-
Natural methods: Some people use oil pulling, coconut oil, or activated charcoal. These can offer mild whitening effects but come with risks, such as abrasiveness or irritation.
For those looking for an at-home option that’s gentle yet effective, SNOW Whitening Products combine fluoride protection with advanced LED-powered technology. They are formulated to protect enamel, target both surface and deeper stains, and leave your smile brighter without sensitivity.
Each of these approaches has its place, but partnering with your dentist ensures you choose what is safest and most effective for your teeth and gums.
Final Thoughts
So, is it baking soda safe for brushing? Yes, but only as an occasional supplement. Baking soda can help remove stains, balance pH, and fight plaque. But remember, it cannot replace fluoride. That’s why the best routine is to brush and floss daily with a fluoride toothpaste and use baking soda sparingly for a little boost.
At SNOW, we believe whitening should protect as much as it brightens. From our Whitening Toothpaste with Hydroxyapatite to our best-selling SNOW Whitening Kit, our products are designed to lift stains safely, support oral health, and give you a confident, lasting glow.
Frequently Asked Questions
Still have questions? Let’s clear up the most common concerns about brushing your teeth with baking soda.
Do dentists recommend brushing with baking soda?
Yes, dentists often say that brushing with baking soda can be safe and helpful, but only when used occasionally and correctly. They usually suggest pairing it with a fluoride toothpaste rather than relying on baking soda alone, since fluoride is essential for protecting enamel and preventing cavities.
What’s the best thing to brush your teeth with?
The best thing to brush your teeth with is a fluoride toothpaste that has the American Dental Association Seal of Acceptance. These toothpastes protect against tooth decay, strengthen enamel, and maintain overall oral health. For added whitening power, SNOW Whitening Toothpaste with Hydroxyapatite is a safe choice that also supports enamel strength.
Can brushing with baking soda damage my teeth?
Yes, brushing with baking soda can damage your teeth if you use it too often or scrub too aggressively. Its abrasive texture may wear down tooth enamel over time, causing sensitivity. To stay safe, use baking soda gently and in moderation, and always follow up with a fluoride toothpaste.
How often should I brush my teeth with baking soda?
You should brush your teeth with baking soda no more than once or twice a week. This schedule helps polish away surface stains without risking enamel erosion. For daily use, stick with a fluoride toothpaste or a balanced formula like SNOW Whitening Toothpaste, which combines whitening benefits with enamel protection.
Can I mix baking soda with other ingredients for whitening?
You can mix baking soda with water or fluoride toothpaste, but avoid combining it with acidic substances such as lemon juice or vinegar. These can erode enamel quickly. If you want to safely boost whitening, look for products with hydrogen peroxide or consult your dentist for tailored recommendations.
Is baking soda safe for kids?
No, baking soda on its own isn’t the best option for kids because children need fluoride toothpaste to strengthen developing teeth and protect against tooth decay. Stick to kid-friendly fluoride products, and save whitening treatments for later in life when their enamel is fully developed.
