Bad breath (clinically known as halitosis) is more common than most people realize, and it can be a surprisingly tricky problem to tackle. While mouthwash gets a lot of credit, the right toothpaste covers the plaque-and-gum share of the problem between dental visits. We dug into the research, consulted expert sources, and evaluated the most talked-about formulas to help you find the best toothpaste for bad breath that delivers. For a full routine, combining your toothpaste with the best mouthwash for bad breath gives you two layers of protection against halitosis throughout the day.
How We Evaluated
We didn’t just browse Amazon reviews. Our evaluation process involved cross-referencing dental expert opinions, peer-reviewed ingredient research, and the Reddit threads we read for this guide. We looked specifically at:
- Active ingredients known to address the root causes of bad breath (volatile sulfur compounds, or VSCs)
- Fluoride content for overall cavity protection, as recommended by the American Dental Association and supported by the ADA’s toothpaste guidance
- Presence of antibacterial agents like zinc compounds, triclosan-free alternatives, and stannous fluoride
- SLS (sodium lauryl sulfate) content, which some users find irritating or drying
- Accessibility and price across a range of budgets
TheraBreath Deep Clean Toothpaste
TheraBreath Deep Clean Toothpaste
Best for: Bad breath that comes with plaque and gum inflammation
- 0.454% stannous fluoride (0.14% fluoride ion), labeled anticavity and antigingivitis
- Listing claims it kills 99.9% of germs that cause bad breath, plaque, and gingivitis (TheraBreath's claim)
- Contains sodium lauryl sulfate; not an SLS-free paste
- 2-pack of 4 oz tubes, Fresh Mint

Why We Recommend It
Know which TheraBreath toothpaste this is. The product our link goes to is TheraBreath Deep Clean, and its Drug Facts label, verified in September 2026, lists 0.454% stannous fluoride as the only active, with anticavity and antigingivitis purposes; it is not an OXYD-8 (sodium chlorite) paste, whatever older reviews say. TheraBreath’s sodium-chlorite OXYD-8 chemistry lives in its rinses; its OXYD-8 Fresh Breath toothpaste was listed as currently unavailable on Amazon when we checked in September 2026. Deep Clean still earns the top spot because stannous fluoride is the toothpaste active with halitosis evidence: a 2019 systematic review of stabilized stannous fluoride pastes reported significant reductions in halitosis alongside plaque and gingivitis, while rating the halitosis studies as high risk of bias and calling for better trials.
Key Features
- 0.454% stannous fluoride, labeled anticavity and antigingivitis
- TheraBreath claims it kills 99.9% of the germs that cause bad breath, plaque, and gingivitis (the brand’s claim, not ours)
- Pairs with TheraBreath’s sodium chlorite (OXYD-8) rinses for the breath-specific step
- 2-pack of 4 oz tubes
Who It’s Best For
People whose bad breath comes with plaque, bleeding, or inflamed gums, since those are the causes a stannous fluoride paste addresses. Because it contains sodium lauryl sulfate, it is not the pick for a dry or canker-sore-prone mouth; our SLS-free toothpaste roundup covers those.
Potential Downsides
The mint is milder than many drugstore pastes, which some users read as “not working.” It contains sodium lauryl sulfate, so it is not the gentle SLS-free paste TheraBreath’s rinses might lead you to expect. And like every toothpaste on this page, it addresses the plaque and gum share of bad breath; tongue coating and gum disease need a tongue scraper and a dental cleaning, not another paste.

Colgate Total Clean Mint
Colgate Total Clean Mint
Best for: All-in-one daily protection with a stannous fluoride antibacterial base
- 0.454% stannous fluoride, labeled anticavity, antigingivitis, and antisensitivity
- Colgate claims 24-hour antibacterial protection (the brand's claim)
- Contains sodium lauryl sulfate
- Ships as a 4-pack of 5.1 oz tubes, about $4.77 per tube
(Affiliate link) · Free shipping on eligible Prime items
Why We Recommend It
Know which Colgate this is: the listing we link is the Clean Mint version of Colgate Total, sold as a 4-pack, and its Drug Facts label, verified in September 2026, lists 0.454% stannous fluoride with anticavity, antigingivitis, and antisensitivity purposes. Colgate has since rebranded the Total line as Active Prevention; the active ingredient did not change. Stannous fluoride is the antibacterial form of fluoride, and a 2019 systematic review of stabilized stannous pastes reported reductions in plaque, gingivitis, calculus, and halitosis, while rating the halitosis studies as high risk of bias. That gum-and-plaque action is the mechanism that matters for breath.
Key Features
- 0.454% stannous fluoride, the antibacterial fluoride
- Anticavity, antigingivitis, and antisensitivity purposes on one label
- Contains sodium lauryl sulfate
- Ships as a 4-pack of 5.1 oz tubes, about $4.77 per tube
Who It’s Best For
Anyone who wants an all-in-one daily toothpaste that addresses gum-related bad breath alongside cavity protection, from a mainstream drugstore brand. Expect to pay around $19 for the 4-pack.
Potential Downsides
Contains SLS, which a 2019 review linked to canker sores in susceptible people and which some users report as drying; if that is you, Biotène below is the SLS-free pick on this page, and our SLS-free toothpaste roundup has more. Some long-time users report the reformulated paste tastes different from the old Total, and a minority of users report mouth soreness on stannous pastes generally.

Biotène Fluoride Toothpaste
Biotène Fluoride Toothpaste
Best for: Bad breath caused by dry mouth
- Marketed for dry mouth; the label reads 'GENTLE FORMULA' and 'SLS FREE'
- 0.25% sodium fluoride for cavity protection, per the Amazon listing
- Cocamidopropyl betaine as the detergent instead of SLS
- No enzymes on the current label, whatever older reviews say
(Affiliate link) · Free shipping on eligible Prime items
Why We Recommend It
Dry mouth is a common contributor to bad breath. Saliva helps keep harmful germs in check, and the NIDCR notes that hundreds of medicines reduce it, so bad breath often follows a new prescription. Biotène’s toothpaste is the gentle option for that mouth: its Drug Facts label, verified in September 2026, lists sodium fluoride as the active (0.15% w/v fluoride ion; the Amazon listing gives it as 0.25% sodium fluoride) and cocamidopropyl betaine rather than sodium lauryl sulfate as the detergent, and the package reads “SLS FREE” and “GENTLE FORMULA.” One label fact to know: the current formula lists no enzymes, whatever older reviews say, and it does not claim to stimulate saliva. What it offers is standard-strength fluoride in a low-foam paste a dry mouth can tolerate, which matters because dry mouth raises cavity risk.
Key Features
- Marketed for dry mouth; low foam, mild mint
- 0.25% sodium fluoride for cavity protection
- SLS-free, with cocamidopropyl betaine as the detergent
- No enzymes or saliva-stimulating claim on the current label
Who It’s Best For
People whose bad breath is linked to dry mouth, particularly those on medications (like antihistamines, antidepressants, or blood pressure drugs) that commonly cause reduced saliva flow.
Potential Downsides
Biotène doesn’t have the strong breath-freshening punch of a dedicated halitosis formula. If your bad breath stems primarily from bacteria rather than dry mouth, this may not be your most effective option. And not every dry mouth tolerates it: in a February 2026 r/Sjogrens thread, one poster wrote, “Biotene is suddenly irritating my mouth (noticed this change with manufacturer changing from gsk to Haleon),” and a reply added, “I use Oral7 toothpaste as I found Biotene to burn.” If it stings, switch rather than push through. At around $14 for a 2-pack of 4.3 oz tubes (about $7 a tube), it’s an inexpensive way to test whether dry mouth is actually your trigger.

Tom’s of Maine Wicked Fresh Toothpaste
Tom's of Maine Wicked Fresh Toothpaste
Best for: Natural-flavor buyers who still want fluoride
- 0.76% sodium monofluorophosphate for cavity protection, per the Drug Facts label
- Spearmint flavor with xylitol; no artificial colors, preservatives, or sweeteners, per Tom's of Maine
- Contains sodium lauryl sulfate and carrageenan; not an SLS-free paste
- The linked listing is a 2-pack of 4.7 oz Spearmint Ice tubes
(Affiliate link) · Free shipping on eligible Prime items
Why We Recommend It
For readers who want a natural-flavor paste that keeps fluoride, Tom’s of Maine Wicked Fresh is the pick: its Drug Facts label lists 0.76% sodium monofluorophosphate as the anticavity active, and the Spearmint Ice inactive list carries xylitol rather than artificial sweeteners. Read the rest of that label before you buy on the “natural” word alone: the inactive list includes sodium lauryl sulfate and carrageenan, so this is a conventional foaming paste with natural flavoring, not an SLS-free formula.
Key Features
- Fluoride anticavity protection (0.76% sodium monofluorophosphate)
- Natural mint oils and xylitol for flavor
- Contains sodium lauryl sulfate and carrageenan
- 2-pack of 4.7 oz tubes
Who It’s Best For
People who want a recognizable natural-flavor brand without giving up fluoride. It is not the pick for canker-sore-prone or peeling-prone mouths; for those, Biotène above or our SLS-free toothpaste roundup.
Potential Downsides
It has no gum-health active (no stannous fluoride, no zinc), so for breath that comes with bleeding gums the stannous picks above do more. It contains SLS, which the natural positioning can obscure. And at around $21.50 for the 2-pack, about $10.75 a tube, it is the most expensive paste per tube on this page.

Sensodyne Pronamel Fresh Breath
Sensodyne Pronamel Fresh Breath
Best for: Sensitive teeth with enamel concerns and bad breath
- 5% potassium nitrate and 0.25% sodium fluoride, per the Drug Facts label; cocamidopropyl betaine rather than SLS
- Fluoride-based cavity protection
- Fights acid erosion from diet
- Fresh mint flavor without being overpowering
(Affiliate link) · Free shipping on eligible Prime items
Why We Recommend It
Sensitivity and bad breath don’t have to be a package deal. Sensodyne Pronamel Fresh Breath was designed to tackle both, making it one of the few options on this list that bridges two common oral concerns. Its Drug Facts label lists 5% potassium nitrate for sensitivity and 0.25% sodium fluoride for cavities, with cocamidopropyl betaine rather than sodium lauryl sulfate as the detergent, and the ADA lists potassium and stannous pastes among those that can be recommended for dentine hypersensitivity pain.
Key Features
- 5% potassium nitrate (antihypersensitivity) and 0.25% sodium fluoride (anticavity) on the Drug Facts label
- Fluoride-based cavity protection
- Fights acid erosion from diet
- Fresh mint flavor without being overpowering
Who It’s Best For
People with sensitive teeth or enamel concerns who also want to address bad breath. It’s particularly useful for those who consume acidic foods and drinks regularly, since the label pairs enamel protection with sensitivity relief.
Potential Downsides
Sensitivity toothpastes generally require consistent, long-term use before the desensitizing effects kick in. Additionally, this isn’t a clinical halitosis treatment: it works best as part of a complete oral hygiene routine. At around $23 for a 4-pack of 4 oz tubes (about $5.79 a tube), the listing sits at the premium end of this roundup.

Crest Complete Whitening + Scope
Crest Complete Whitening + Scope
Best for: Whitening and fresh breath in one formula
- 0.243% sodium fluoride anticavity paste with whitening abrasives, per the Drug Facts label
- Scope flavoring; cetylpyridinium chloride appears on the inactive list, not as a labeled active
- Crest claims it kills bad-breath germs (the brand's claim)
- 3-pack of 5.4 oz tubes, about $3 a tube
(Affiliate link) · Free shipping on eligible Prime items
Why We Recommend It
If you want to address bad breath while also brightening your smile, Crest Complete Whitening + Scope is the budget two-for-one. Its Drug Facts label lists 0.243% sodium fluoride as the only active; the Scope part is flavoring plus cetylpyridinium chloride, an antiseptic used in some mouth rinses, which appears here among the inactive ingredients rather than as a labeled active. Crest’s package claim is that it kills germs that cause bad breath; treat that as the brand’s claim. What you can count on from the label is standard fluoride cavity protection and a whitening abrasive in a strongly minty paste.
Key Features
- 0.243% sodium fluoride with whitening abrasives
- Scope flavoring, with cetylpyridinium chloride on the inactive list
- Crest’s germ-kill claim is the brand’s, not a labeled purpose
- A mainstream drugstore brand
Who It’s Best For
People who want a do-it-all daily toothpaste that addresses breath, whitening, and basic cavity protection without adding extra steps to their routine. At around $9 for a 3-pack of 5.4 oz tubes, roughly $3 per tube, it’s also the cheapest pick on this list.
Potential Downsides
Contains SLS, and unlike Sensodyne Pronamel Fresh Breath it carries no sensitivity ingredient: sodium fluoride is its only active. It’s more of a maintenance option than a clinical-strength breath solution.

Buyer’s Guide: What to Look For
Choosing a toothpaste for bad breath isn’t just about picking the mintiest option on the shelf. Here’s what we recommend paying attention to:
Antibacterial Active Ingredients
Look for stannous fluoride first; zinc and chlorine dioxide are marketed for the same job, though none of our picks carries them. These ingredients are aimed at the bacteria that produce sulfur compounds rather than at masking the smell. A 2019 systematic review found stabilized stannous fluoride pastes reduced plaque and gingivitis, which is the antibacterial action that matters here. If you’d rather skip these actives altogether, a ready-to-use oil pulling rinse is a natural-breath alternative some readers prefer.
Fluoride Content
The ADA calls fluoride safe and effective for preventing tooth decay in children and adults, and recommends brushing with a fluoride toothpaste. Unless you have a specific medical reason to avoid fluoride, we recommend sticking with a fluoride-containing formula. If cavity prevention is equally important to you, our roundup of the best toothpaste for cavities covers the top fluoride formulas in detail.
SLS (Sodium Lauryl Sulfate)
SLS is a foaming agent found in most mainstream toothpastes. While it’s generally considered safe, a 2019 systematic review of crossover trials found SLS-free toothpaste reduced the number, duration, and pain of recurrent canker sores, and some users report SLS pastes as drying. If you notice mouth irritation or worsening dry mouth with your current toothpaste, switching to an SLS-free formula is worth trying.
Zinc Compounds
Zinc citrate and zinc chloride are marketed for neutralizing volatile sulfur compounds (VSCs), the gases behind most bad breath. None of the picks on this page carries zinc, so we have not evaluated a zinc paste here.
Avoid Over-Relying on Flavor
Strong mint flavor can make toothpaste feel effective even when it isn’t doing much about the underlying bacteria. Focus on active ingredients, not just how minty it tastes. If you’d rather work on the bacterial cause directly, dental probiotics target the oral microbiome instead of covering odor with flavor.
FAQ
Q: Can toothpaste alone cure bad breath? A: Toothpaste is an important part of the solution, but it’s rarely the whole answer. Bad breath usually has several contributing factors, including bacteria on the tongue, gum disease, dry mouth, diet, and even systemic health conditions. A complete routine that includes tongue scraping, flossing, and regular dental checkups is important alongside using the right toothpaste. Gum disease in particular is a major driver of persistent halitosis: the best toothpaste for gum disease can help address that underlying cause.
Q: How often should I brush to help with bad breath? A: The ADA recommends brushing twice daily for two minutes each session. For those dealing with persistent bad breath, brushing after meals and before bed (and paying particular attention to the tongue) may help with reducing bacterial buildup throughout the day.
Q: Is fluoride toothpaste safe? A: Yes. In age-sized amounts. The ADA recommends a rice-grain smear from the first tooth until age 3 and a pea-sized amount from 3 to 6, to minimize swallowing.
Q: What’s the difference between toothpaste for bad breath and regular toothpaste? A: Toothpastes marketed for bad breath may lean on stannous fluoride, zinc compounds, or chlorine dioxide, but the label decides: our top pick’s only active is stannous fluoride. Regular toothpastes focus primarily on fluoride and mild abrasives for cavity prevention and surface stain removal.
Q: Can bad breath be a sign of a more serious health issue? A: In some cases, yes. While most bad breath originates in the mouth, persistent halitosis that doesn’t respond to oral hygiene improvements can sometimes indicate issues such as gastroesophageal reflux, sinus conditions, or systemic health concerns. The ADA’s MouthHealthy guide advises making an appointment with your dentist if you’re concerned about what’s causing your bad breath, and says that if your dentist finds your mouth healthy, you may be referred to your primary care doctor. Our guide to bad breath from stomach issues walks through how to tell whether reflux or another digestive cause is behind breath that doesn’t clear up with better oral hygiene.
Q: Are natural toothpastes as effective for bad breath? A: Natural-positioned toothpastes vary; the ones worth considering keep fluoride, and we can point to no trial evidence for essential-oil breath claims. Not all natural formulas contain fluoride, so it’s worth checking labels carefully. If you prefer a natural-flavor option, Tom’s of Maine Wicked Fresh is our pick: it pairs a spearmint flavor with fluoride anticavity protection and skips artificial sweeteners, though its label does list sodium lauryl sulfate.
Our Methodology
At Dental Roundup, we approach every product evaluation as if we’re advising a trusted friend, not writing an advertisement. For this roundup, our process included:
- Ingredient analysis: We reviewed the active and inactive ingredient lists for each product, cross-referencing with dental research and ADA guidance on safe and effective formulations.
- Label and guidance review: We read each product’s FDA Drug Facts label on DailyMed and the ADA’s toothpaste guidance, and cite a systematic review wherever the page makes an efficacy claim.
- User experience research: We read each product’s US Amazon listing and the Reddit threads we read to identify consistent patterns in real-world performance, including ease of use, taste, sensitivity issues, and perceived breath improvement.
- Value assessment: We compared price-per-ounce and overall accessibility to ensure our picks span a range of budgets without sacrificing effectiveness.
- Health claim standards: We only include health benefit claims that are supported by ADA guidance, the product’s Drug Facts label, or published dental research; a brand’s own claim is labeled as the brand’s. We do not claim any product “cures” or “treats” halitosis: only that certain ingredients may help with reducing the contributing factors.
