If you’ve ever swished with a standard paste and felt that immediate sting or a raw sensation along your gumline, what you’re actually reacting to is a cocktail of sodium lauryl sulfate (SLS), artificial brighteners, and high-abrasion silica. Baking soda toothpaste offers a fundamentally different approach—using the mild crystalline structure of sodium bicarbonate to mechanically lift stains without stripping enamel, while its natural alkalinity neutralizes the acids that feed cavity-causing bacteria.
I’m Mohammad Maruf — the founder and writer behind WellFizz. I’ve spent years breaking down the chemical profiles and abrasivity data of oral care formulations, cross-referencing customer sentiment with hard spec sheets so you don’t have to gamble on a tube that leaves your mouth worse off.
After analyzing dozens of formulas on abrasivity, fluoride content, and enamel safety, I’ve narrowed the field to the five that actually deliver on their promises. Whether you’re battling sensitivity, avoiding fluoride, or just want a genuinely clean feeling without the burn, this guide to the best baking soda toothpaste will steer you to the right pick.
How To Choose The Best Baking Soda Toothpaste
Baking soda toothpaste isn’t a one-size-fits-all category. The same ingredient that gently whitens can also leave teeth feeling gritty if the particle size isn’t managed. Here’s what to actually look for on the label before you buy.
Check for Potassium Nitrate if You Have Sensitive Teeth
Baking soda alone won’t stop the sharp jolt from cold water. Potassium nitrate—a clinically proven desensitizing agent—blocks the nerve signals in porous dentin. If sensitivity is your primary complaint, a formula that lists potassium nitrate as an active ingredient is non-negotiable.
Decide on Fluoride vs. Fluoride-Free
Many natural brands skip fluoride entirely, relying on baking soda’s acid-neutralizing power and gentle abrasion for cleaning. If cavity history is a concern, choose a paste with sodium fluoride (0.24% is the standard anticavity dose). If you prefer to avoid it, look for a balanced pH formula and pair it with a fluoride mouthwash.
Look for Low RDA Ratings
Relative Dentin Abrasivity (RDA) measures how much a toothpaste wears down enamel. Baking soda pastes typically score between 40–80, well under the ADA safety limit of 250. Pastes with added hydrated silica or calcium carbonate can push that number higher, so if you have exposed roots, stick with formulas that explicitly state low abrasion.
Avoid SLS if You Get Canker Sores
Sodium lauryl sulfate creates foam but also irritates soft tissue in some people, triggering canker sores. Many premium baking soda toothpastes now advertise SLS-free formulas. If your mouth feels raw after brushing, switch to an SLS-free baking soda paste first—it’s often the simplest fix.

In‑Depth Reviews
1. ARM & HAMMER Sensitive Teeth & Gums Toothpaste
The dual active system—potassium nitrate at 5% and sodium fluoride at 0.24%—addresses the two main complaints in one squeeze: sensitivity and cavity risk. The baking soda base keeps the abrasivity low enough that you can brush twice daily without worrying about enamel erosion, while still lifting surface stains effectively.
Users consistently report that this paste eliminates the “furry” feeling on teeth after meals and reduces the shock of cold water sensitivity. The low-abrasion claim is backed by its parent company GSK, which has its own biopharmaceutical oral-care division—meaning the formulation is built on clinical data, not marketing claims. It’s foamy enough to feel thorough, but not so sudsy that it causes gum irritation.
For anyone who wants a single tube that covers whitening, sensitivity relief, and cavity protection without buying three separate products, this is the straightforward answer. It’s also widely available in multipacks on Amazon, which solves the common complaint of it being hard to find in local stores.
Why it’s great
- Clinically proven potassium nitrate for sensitivity relief within days
- Low abrasivity preserves enamel on exposed roots
- Affordable multipack reduces per-tube cost significantly
Good to know
- Contains fluoride; not suitable for strict fluoride-free users
- Mint flavor is mild but not “natural” in the way organic brands offer
2. Tom’s of Maine Whiten Plus Coconut Oil Toothpaste
Tom’s of Maine has long been a household name in natural oral care, and the Whiten Plus Coconut Oil variant brings their formula into the baking soda category with a plant-based twist. The whitening mechanism relies on naturally derived micro-polishers (hydrated silica) and plant-based cleansers rather than peroxide or synthetic abrasives, which means it lightens stains without triggering the sharp sensitivity that peroxide-based whiteners often cause.
Clinical data from the brand shows it removes up to 95% of surface stains after two weeks of twice-daily use. The coconut oil adds a subtle lubricity that helps the paste glide smoothly, and the gentle mint flavor is mild enough that you won’t get that burning sensation some mint toothpastes leave behind. It’s also free of SLS, artificial flavors, and dyes—making it a safe bet for those with chronic canker sores.
One thing to note: because it lacks fluoride, this paste won’t actively remineralize enamel. If you’re cavity-prone, you’ll want to pair it with a fluoride rinse. But for the user who wants a clean, bright smile without chemical additives, Tom’s offers one of the most clinically backed fluoride-free options on the shelf.
Why it’s great
- Clinically proven 95% surface stain removal in two weeks
- No peroxide means no sharp whitening sensitivity
- Plant-based cleansers and SLS-free formula for sensitive mouths
Good to know
- Fluoride-free; may need supplemental fluoride for cavity prevention
- Low foam volume may feel unusual if you’re used to sudsy pastes
3. Burt’s Bees Extra White Toothpaste, Mountain Mint
Burt’s Bees Extra White is one of the few baking soda toothpastes that carries the ADA seal while remaining free of SLS, triclosan, parabens, and artificial dyes. The formula uses sodium fluoride for cavity protection and hydrated silica for gentle whitening, achieving a balance that satisfies both the natural-care advocate and the dentist who wants clinical validation. The texture is noticeably smooth and creamy, which helps it spread evenly without a gritty mouthfeel.
Users with chronic lip allergies or canker sores have reported that switching to this paste resolved their irritation within a week. The mountain mint flavor is fresh but not overpowering, and the post-brush freshness lasts noticeably longer than many SLS-heavy competing pastes. Some long-term users note that the formula can leave a mild white sediment on electric toothbrush heads, requiring a quick rinse after each use.
The 4.7 oz tubes are slightly larger than the industry-standard 4 oz, giving you a bit more mileage per tube. For the buyer who wants the peace of mind of ADA acceptance but refuses to compromise on clean ingredients, this is the tier-one pick.
Why it’s great
- ADA accepted with SLS-free and paraben-free certification
- Helped users resolve lip allergies and canker sore outbreaks
- Smooth, creamy texture with no artificial dyes or sweeteners
Good to know
- May leave sediment on electric toothbrush heads requiring wiping
- Contains fluoride; not suitable for fluoride-free regimens
4. Native Fluoride Free Whitening Toothpaste
Native’s entry into the toothpaste space is built on a hyper-clean ingredient deck: just 12 components, all naturally derived, with no fluoride, SLS, parabens, artificial sweeteners, or gluten. The whitening comes from mineral-based hydrated silica, and the peppermint oil gives a crisp, lively flavor without the burn of synthetic mint isolates. The baking soda here acts as both a mild abrasive and a pH buffer, keeping the mouth’s environment less hospitable to acid-producing bacteria.
Users note that the consistency is slightly looser than conventional pastes—closer to a gel-cream hybrid—which takes a day or two to adjust to. But once you do, the clean feeling is remarkably persistent. Several reviewers mention that even hours after brushing, their teeth still feel smooth and their breath fresh. The Wild Mint & Peppermint Oil flavor is one of the most praised aspects; it’s strong enough to feel effective but not so aggressive that it lingers into your morning coffee.
Native also positions this as safe for kids ages two and up, which makes the three-pack a practical buy for families who want a single paste for everyone. If you prioritize ingredient transparency and want a fluoride-free option that still delivers a satisfying clean, this is the pack to grab.
Why it’s great
- Only 12 naturally derived ingredients, no questionable additives
- Pea-sized amount lasts for months due to efficient consistency
- Family-safe for ages 2+, making the multipack highly practical
Good to know
- Loose consistency may feel unusual compared to standard pastes
- Fluoride-free; not ideal for high-cavity-risk individuals
5. Tea Tree Therapy Toothpaste with Baking Soda
Tea Tree Therapy takes a different approach by leveraging tea tree oil’s natural antiseptic properties as the primary active agent, with baking soda as the mechanical cleaner. The result is a paste that feels particularly effective at reducing morning “furry” tooth coating and keeping gums feeling firm. It’s fluoride-free and mint-free, relying on the camphoraceous notes of tea tree oil for flavor—a divisive point that some love and others find medicinal.
Long-term users swear by it for preventing plaque buildup and tartar between dental cleanings, with several noting that their hygienist has commented on reduced calculus since switching. The baking soda content is noticeable in the texture—slightly more granular than the other pastes on this list—which some find satisfyingly thorough while others wish it were creamier. The formula recently underwent a minor change that a few long-time users felt altered the original texture slightly.
For the health-conscious brusher who wants to avoid fluoride, synthetic chemicals, and mint altogether while still getting an aggressive clean, this is a niche but effective option. It’s also the most budget-conscious choice in the set, making it an easy entry point for anyone curious about tea tree oral care.
Why it’s great
- Natural tea tree oil provides antiseptic cleaning without chemical agents
- Effectively reduces morning plaque buildup and furry tooth sensation
- Fluoride-free, mint-free, and from a small family-owned brand
Good to know
- Tea tree flavor is strong and medicinal; not for everyone
- Recent formula change altered texture slightly for longtime users
