Whitening mouthwash won’t replace professional treatments or whitening strips, but used consistently it can help remove surface stains from coffee, tea, and wine, and prevent new ones from setting in. Most whitening rinses work through low concentrations of hydrogen peroxide (typically 1.5-2%) or through peroxide-free formulas that target surface stains or tartar build-up. The American Dental Association notes that over-the-counter whitening products with the ADA Seal of Acceptance have been evaluated for safety and effectiveness.
We compared the top whitening mouthwashes on the market, evaluating ingredient formulations, user reviews, and value to find the five that balance stain-fighting performance with everyday usability. A rinse maintains results with a 30-second swish added to your existing routine, rather than delivering the concentrated peroxide treatment a complete system uses; for that, see our guide to the best at-home teeth whitening kits. If you’re also looking for a whitening toothpaste to pair with your rinse, see our best whitening toothpaste guide. For broader teeth whitening options, check our best teeth whitening roundup.
How We Evaluated
Not all whitening mouthwashes work the same way, and marketing claims can be misleading. We evaluated each product across five criteria:
- Active whitening ingredients: Does it use hydrogen peroxide, and at what concentration? For peroxide-free options, what’s the whitening mechanism (surfactants, tartar control)?
- Enamel and sensitivity safety: Whitening products can cause sensitivity. We prioritized formulas that are gentle enough for daily use, checking for alcohol content and pH levels where available.
- User-reported results: We cross-referenced thousands of reviews for consistent feedback on visible whitening, taste, and any reported sensitivity.
- Additional oral health benefits: The best whitening rinses also fight cavities, freshen breath, or reduce plaque. A single-purpose product needs to justify skipping a more versatile alternative.
- Value: Price per ounce and per-use cost, factoring in whether the product is a concentrate or standard dilution.

Why We Recommend It
Crest Pro-Health Advanced has earned its position as the most-reviewed whitening mouthwash on Amazon for a reason. With over 20,000 reviews and a 4.7-star average, it has the deepest pool of user validation in this category. The formula is alcohol-free, which matters because alcohol-based rinses can dry out your mouth and actually contribute to staining over time.
The whitening mechanism here is stain prevention rather than aggressive bleaching. Crest’s drug-facts label lists sodium fluoride 0.02% as the active ingredient for cavity protection, and hydrogen peroxide appears among the inactive ingredients with no concentration stated, alongside a poloxamer surfactant; Crest says the rinse helps whiten and strengthen enamel. It’s a multi-benefit formula that lets you combine whitening with your daily oral care rather than adding a separate step.
The listing leads with two comforts: it is alcohol-free, so there is no burn of alcohol, and it comes in an Energizing Mint flavor. For most people, this combination of effectiveness, comfort, and value makes it the easiest recommendation.
Key Features
- Alcohol-free formula that won’t dry out your mouth or cause burning
- Multi-benefit: whitening, cavity protection, enamel strengthening, fresh breath
- Energizing Mint flavor with broad positive taste feedback
- 32 oz (946 mL) bottle at a competitive price point
- Sodium fluoride 0.02% as the listed active ingredient
Who It’s Best For
This is our top pick for anyone who wants to add whitening to their mouthwash routine without changing anything else. If you currently use a non-whitening rinse and want to upgrade, or if you’ve been skipping mouthwash entirely and want to start with a versatile option, this is the one. It’s particularly well-suited for people with sensitive mouths who can’t tolerate alcohol-based rinses.
Potential Downsides
Crest lists hydrogen peroxide only as an inactive ingredient and gives no strength for it, so don’t expect dramatic whitening results on deeply set stains. It’s better at preventing new stains and gradually lifting light surface discoloration than at transforming already-yellowed teeth. If you’re looking for more aggressive whitening, consider the Colgate Optic White (our #2 pick), which names 2% hydrogen peroxide as its whitening agent. Some users also report a slight film after rinsing, though this typically dissipates within minutes.

Colgate Optic White Advanced Whitening Mouthwash
Colgate Optic White Advanced Whitening Mouthwash
Best for: People who want a 2% hydrogen peroxide rinse, the whitening agent covered by the 2014 evidence review below
- 2% hydrogen peroxide — among the highest OTC mouthwash concentrations
- Icy Fresh Mint flavor with no alcohol burn
- 3-pack (32 oz each) for excellent per-ounce value
- Colgate's Optic White whitening line
- +2% hydrogen peroxide — among the highest OTC concentrations for active stain removal
- +Alcohol-free despite the peroxide active, comfortable for daily use
- +3-pack format brings down per-ounce cost for committed daily users
- −Peroxide can cause temporary tooth sensitivity, especially the first week or two
- −3-pack format means a higher upfront cost
(Affiliate link) · Free shipping on eligible Prime items
Why We Recommend It
If you want the whitening ingredient that dentists actually use (hydrogen peroxide) in a daily rinse, Colgate Optic White Advanced delivers one of the highest concentrations available over the counter at 2%. Research supports hydrogen peroxide’s effectiveness for teeth whitening: a 2014 review in the Journal of Evidence-Based Dental Practice concluded that hydrogen peroxide and carbamide peroxide whitening is safe and effective when label instructions are followed. Tooth sensitivity and gum irritation are the long-recognized risks it names; the same review also catalogues newer findings on enamel surface roughening and softening, which the enamel question in our FAQ covers.
The formula is alcohol-free, which is a welcome combination with the peroxide active. The Icy Fresh Mint flavor has strong positive feedback across nearly 7,000 reviews: users describe it as refreshing without the harsh chemical taste that some peroxide products carry. The 3-pack format (three 32 oz bottles) brings the per-ounce cost down significantly, making it one of the better values if you commit to daily use.
What separates Colgate Optic White from the pack is that it’s specifically engineered around hydrogen peroxide as the whitening agent, not as an afterthought. Optic White is Colgate’s whitening-focused range, and the mouthwash is designed to complement their whitening toothpaste for a combined effect.
Key Features
- 2% hydrogen peroxide as the active whitening ingredient
- Alcohol-free formula for comfortable daily use
- Three 32 oz bottles per package for extended supply
- Part of Colgate’s Optic White whitening line
- Compatible with whitening toothpaste for enhanced results
Who It’s Best For
This is the pick for people who want science-backed whitening power and are willing to follow a consistent routine. If you drink a lot of coffee, tea, or red wine and want a rinse that actively works on those stains (not just prevents future ones), the peroxide formulation gives you more whitening power than non-peroxide alternatives. It pairs especially well with a whitening toothpaste for a two-step whitening routine.
Potential Downsides
Hydrogen peroxide can cause temporary tooth sensitivity in some users, especially during the first week or two of use. If you already have sensitive teeth, you may want to start with every-other-day use and see how you respond. The 2% concentration sits at the top of the over-the-counter rinse range rather than anywhere near professional strength, and the 2014 review above puts label-directed peroxide whitening in the safe-and-effective column, but some people find peroxide rinses slightly more drying than non-peroxide alternatives. The 3-pack format is great for value but means a higher upfront cost.

GuruNanda Dual Barrel Oxyburst Whitening Mouthwash
GuruNanda Dual Barrel Oxyburst Whitening Mouthwash
Best for: People who want a peroxide whitening rinse without alcohol or fluoride, with essential oils and xylitol in the formula
- Dual-chamber bottle keeps hydrogen peroxide apart from a second chamber of essential oils, baking soda and xylitol until you pour
- Seven essential oils plus vitamins D3 and E, per the listing
- Alcohol-free, fluoride-free formulation
- Wild Mint flavor, 20 fl oz bottle, 4.6 stars across 8,400+ ratings
- +Dual-chamber bottle keeps the hydrogen peroxide in its own chamber until you pour
- +Second chamber holds 7 essential oils, baking soda and xylitol, per the listing
- +Alcohol-free and fluoride-free, with no artificial colors or flavors, per the listing
- −You pour 15 ml from each chamber, so it takes more care than a single-bottle rinse
- −Fluoride-free, so it adds no fluoride cavity protection
(Affiliate link) · Free shipping on eligible Prime items
Why We Recommend It
GuruNanda’s Dual Barrel design is unlike anything else in this category. The bottle has two separate chambers: one holds hydrogen peroxide, and the other holds seven essential oils, baking soda and xylitol, per the listing. The two mix only when you pour, so the peroxide stays apart from everything else until the moment of use.
The listing calls the mixed rinse pH-balanced, with baking soda as the buffer, and says its “Oxy-burst” bubbles gently lift surface stains. It also calls the formula veneers-friendly. Those are the maker’s descriptions; we have no independent test of what the bubbles add beyond the peroxide itself.
With over 8,400 reviews and a 4.6-star rating, the user reception has been strong. The listing makes no whitening-timeline promise.
Key Features
- Dual-chamber design keeps hydrogen peroxide apart until each use
- Second chamber of seven essential oils, baking soda and xylitol, per the listing
- Alcohol-free and fluoride-free
- 20 fl oz bottle
- No artificial colors or flavors, per the listing
Who It’s Best For
People who want a peroxide whitening rinse without alcohol or fluoride, and who like a formula built around essential oils and xylitol. If other peroxide rinses have felt harsh, note that the listing calls this one gentle, though that is the maker’s word. If you want fluoride in your rinse, the Crest Pro-Health pick above has it.
Potential Downsides
The dual-barrel bottle is clever but can be slightly awkward to pour evenly from both chambers. The listing has you pour 15 ml from each chamber and rinse for one minute, which takes a little more care than a single-bottle rinse. As with any peroxide-based product, temporary sensitivity is possible. It is also fluoride-free, so unlike the Crest Pro-Health pick it adds no fluoride cavity protection.

Listerine Ultraclean Antiseptic Mouthwash (Intense Mint)
Listerine Ultraclean Antiseptic Mouthwash (Intense Mint)
Best for: Listerine loyalists who want tartar and stain control from the Ultraclean line, whose Antiseptic Ultraclean rinse (pictured by the ADA in Cool Mint) carries the ADA Seal for plaque and gingivitis
- Combines Listerine's essential oil antiseptic with whitening protection that Listerine defines as preventing tartar build-up
- Tartar control from the Ultraclean line, whose Antiseptic Ultraclean rinse (pictured by the ADA in Cool Mint) holds the ADA Seal for plaque above the gumline and gingivitis
- Intense Mint flavor in the classic Listerine style
- Fluoride-free formula focused on antiseptic and whitening action
- +Adds genuine antiseptic power from the essential-oil formula behind the Ultraclean line's ADA Seal for plaque and gingivitis
- +Most well-rounded pick for total oral health, with whitening as a bonus
- +Backed by Listerine's 140+ years of dental professional trust
- −Strong taste and tingle that some users describe as a burn
- −Contains alcohol, unlike most other picks, which can be drying
(Affiliate link) · Free shipping on eligible Prime items
Why We Recommend It
Listerine has been a dental professional staple for over 140 years, and the Ultraclean line adds tartar control to its essential-oil antiseptic formula; the Amazon listing we link is sold as the antiseptic Intense Mint rinse, and the whitening effect is stain prevention rather than bleaching. Listerine’s label describes the whitening benefit as helping keep teeth naturally white by preventing tartar build-up, and that sits on top of Listerine’s four essential oils (eucalyptol, menthol, methyl salicylate, and thymol), the formula behind the ADA Seal of Acceptance for Listerine Antiseptic Ultraclean, for helping prevent and reduce plaque above the gumline and gingivitis. The ADA’s entry is pictured in Cool Mint; the Amazon listing we link calls its bottle Intense Cool Mint and lists the same four essential oils at the same strengths as Listerine’s Cool Mint Ultraclean label.
What you get with Listerine that you don’t get from most whitening-only rinses is genuine antiseptic power. The essential oil formula has been shown to help reduce plaque and gingivitis, and shoppers can also look for products carrying the ADA Seal of Acceptance as a general marker that their safety and efficacy data has been reviewed. The whitening component is an added benefit on top of a formula that’s already doing heavy lifting for your oral health.
The 4.7-star rating across 5,500+ reviews reflects a product that delivers on both promises. Users who already know and trust the Listerine experience find the whitening variant to be a natural upgrade.
Key Features
- Essential oil antiseptic formula (eucalyptol, menthol, methyl salicylate, thymol)
- Whitening protection that Listerine defines as preventing tartar build-up
- From the Ultraclean line; the ADA Seal entry for Listerine Antiseptic Ultraclean (plaque above the gumline and gingivitis) is pictured in Cool Mint and does not name this Whitening Protection bottle
- Intense Mint flavor with the signature Listerine intensity
- Established brand with over 140 years of dental professional trust
Who It’s Best For
If you already use Listerine and want to add whitening without switching products, this is the straightforward answer. It’s also the right choice if your primary concern is overall oral health (fighting plaque, reducing gingivitis risk, freshening breath), and you want whitening as a bonus rather than the main event. Listerine’s antiseptic benefits make this the most well-rounded product in terms of total oral health impact.
Potential Downsides
The classic Listerine intensity isn’t for everyone. The essential oil formula has a strong taste and a noticeable tingle that some users describe as a burn. Unlike most other picks on this list, this one contains alcohol, which contributes to that intensity and can be drying. If you have a sensitive mouth or prefer gentle rinses, the alcohol-free Crest Pro-Health (#1) may be more comfortable. The whitening effect is also more modest than dedicated peroxide formulas—it’s primarily a plaque-fighting rinse with added whitening, not the other way around.

Crest 3D White Brilliance Whitening Mouthwash
Crest 3D White Brilliance Whitening Mouthwash
Best for: People willing to pay more for Crest's most advanced whitening rinse
- Highest-rated whitening mouthwash in our roundup at 4.8 stars
- Alcohol-free formula from Crest's premium 3D White line
- 2-pack (1L each) for extended supply
- Designed to complement Crest 3D White toothpaste and strips
- +Highest-rated rinse in the roundup at 4.8 stars
- +Alcohol-free formula from Crest's premium 3D White line
- +Designed to work as a system with Crest 3D White toothpaste and Whitestrips
- −2-pack format means a higher upfront cost (about $23) than the #1 pick
- −Smaller review pool (1,414) means less long-term user data
(Affiliate link) · Free shipping on eligible Prime items
Why We Recommend It
Crest 3D White Brilliance is Crest’s premium whitening mouthwash, a step up from the Pro-Health Advanced (our #1 pick) with a more focused whitening formulation. At 4.8 stars, it’s the highest-rated product in our roundup, though with fewer reviews (1,414) than the more established picks. The formula is alcohol-free and part of Crest’s 3D White line, which is specifically engineered for whitening across toothpaste, mouthwash, and strips.
Crest markets the rinse as peroxide-free and alcohol-free, and its whitening claim is a whiter smile in 7 days with brushing by removing surface stains. Crest has designed the 3D White line to work as a system: the mouthwash is formulated to complement their 3D White toothpaste and Whitestrips, creating a multi-product whitening routine. While you certainly don’t need to buy the whole line, the integration means the mouthwash is optimized for people who take whitening seriously.
The listing describes a Clean Mint flavor in an alcohol-free, peroxide-free formula. The 4.8-star average (among the highest we’ve seen for any mouthwash) suggests strong satisfaction, though the smaller review pool means less statistical confidence compared to our top pick.
Key Features
- Part of Crest’s premium 3D White Brilliance line
- Alcohol-free with a smooth, pleasant mint flavor
- 2-pack format (two 1L bottles) for extended use
- Designed to work as part of a complete Crest 3D White routine
- 4.8-star average — highest satisfaction rating in our roundup
Who It’s Best For
This is for people who prioritize whitening and want the best-reviewed option, even at a higher price point. If you already use Crest 3D White toothpaste or Whitestrips and want to round out your routine, the mouthwash is the logical addition. It’s also a good choice if you tried the Pro-Health Advanced and wanted more noticeable whitening results; the Brilliance line is Crest’s more focused whitening tier.
Potential Downsides
The 2-pack format means a higher upfront cost (about $23 for two 1L bottles) compared to a single bottle of our #1 pick. While the per-ounce cost is reasonable, the review count is lower than our other picks, which means less long-term user data to draw from. As a newer product variant, it also has a much shorter track record than Listerine’s long-established antiseptic rinse. Some users may find the difference between this and the more affordable Crest Pro-Health Advanced doesn’t justify the price premium.

Buyer’s Guide: What to Know Before Choosing a Whitening Mouthwash
How Whitening Mouthwash Actually Works
Whitening mouthwashes generally work through one of two mechanisms. Hydrogen peroxide-based rinses (like Colgate Optic White and GuruNanda) use a low concentration of peroxide to oxidize stain molecules on your tooth surface, breaking them down and lightening their appearance. Non-peroxide rinses (Listerine Ultraclean and Crest 3D White Brilliance here) take other routes: Listerine’s label frames its whitening as preventing tartar build-up, and Crest describes Brilliance as removing surface stains.
Neither type will change the intrinsic color of your teeth: that requires professional bleaching or high-concentration whitening strips. What mouthwash can do is address extrinsic stains from food, drinks, and tobacco, and help prevent new stains from accumulating.
Peroxide vs. Non-Peroxide: Which Should You Choose?
Choose peroxide if you want more aggressive stain removal and don’t have sensitivity issues. The 1.5-2% hydrogen peroxide in OTC rinses is far below the concentrations applied under professional supervision, and the 2014 evidence review cited above found label-directed peroxide whitening to be both safe and effective.
Choose non-peroxide if you have sensitive teeth, prefer gentler products, or want a multi-benefit rinse where whitening is one feature among several (plaque reduction, breath freshening).
What About Alcohol?
Alcohol in mouthwash serves as an antiseptic and a solvent, but it can dry out your mouth, and chronic dry mouth can actually contribute to staining and tooth decay. Most whitening mouthwashes have moved away from alcohol, with Listerine being the notable exception. If you have dry mouth issues, stick with alcohol-free options.
How Long Until You See Results?
Expect 2-4 weeks of consistent daily use before noticing visible improvement with peroxide-based rinses. Non-peroxide options may take longer and produce more subtle results. No mouthwash will deliver overnight whitening—be skeptical of any product that claims otherwise.
Can You Use Whitening Mouthwash With Whitening Toothpaste?
Yes. In fact, many brands (particularly Crest and Colgate) design their whitening mouthwashes to complement their whitening toothpastes. Using both together can provide a more comprehensive stain-fighting routine. Just monitor for sensitivity: if your teeth become sensitive, scale back to one whitening product at a time. If you’re stacking products for the optical brightening effect rather than bleaching, our best purple toothpaste picks cover that layer of the routine too.
For whitening toothpaste recommendations, see our best whitening toothpaste guide.
Frequently Asked Questions
Does whitening mouthwash actually work?
Whitening mouthwash can help with surface stains from coffee, tea, wine, and tobacco when used consistently over several weeks. It won’t change the underlying color of your teeth (that requires professional treatment), but research supports that hydrogen peroxide-based rinses can meaningfully reduce extrinsic discoloration. Results vary based on the product, your staining level, and how consistently you use it.
Is hydrogen peroxide mouthwash safe for daily use?
At the 1.5-2% concentrations used in over-the-counter whitening rinses, daily use is generally considered safe, and the 2014 evidence review cited above reaches that conclusion for label-directed peroxide whitening generally. The ADA has granted its Seal of Acceptance to peroxide-based whitening products such as whitening strips, which have met its standards for safety and effectiveness when used as directed. However, some people may experience temporary tooth sensitivity or mild gum irritation, particularly during the first week. If sensitivity persists, reduce frequency or switch to a non-peroxide option.
Will whitening mouthwash damage my enamel?
Over-the-counter whitening mouthwashes sit at the low end of the peroxide range (1.5-2% hydrogen peroxide), and at label directions the evidence does not point to enamel damage. The 2014 evidence review in the Journal of Evidence-Based Dental Practice cited earlier concludes exactly that: hydrogen peroxide and carbamide peroxide whitening is safe and effective when the manufacturer’s instructions are followed. That same review does catalogue enamel surface roughening and softening among the risks newer research has identified, and the ADA notes that some research suggests bleaching protocols may alter the surface roughness of enamel. Neither of those is a finding that label-directed rinsing damages healthy enamel; both are the reason the directions are the safety margin, so rinsing longer or more often than the label says is the thing to avoid. And if you already have weakened enamel, active cavities, or erosion, check with your dentist before adding any whitening product.
What’s the best mouthwash for both whitening and bad breath?
For combined whitening and breath freshening, the Crest Pro-Health Advanced (our #1 pick) and Listerine Ultraclean Antiseptic (#4) both deliver strong results on both fronts. If bad breath is your primary concern and whitening is secondary, you may want to check our dedicated best mouthwash for bad breath guide.
Can I use whitening mouthwash with braces?
Most whitening mouthwashes are safe to use with braces, but results may be uneven since the brackets cover portions of your teeth. Many orthodontists recommend waiting until braces are removed before starting a whitening regimen. Check with your orthodontist for personalized advice. For braces-friendly mouthwash options, see our best mouthwash for braces guide.
How is whitening mouthwash different from whitening strips or trays?
Whitening mouthwash uses lower peroxide concentrations (1.5-2%) with shorter contact time (30-60 seconds), making it gentler but less powerful. Whitening strips and trays use higher concentrations (5-14% hydrogen peroxide) with longer contact time (30-60 minutes), delivering more dramatic results but with higher sensitivity risk. Mouthwash is best for maintenance and mild stain prevention, while strips and trays are better for noticeable whitening. For strip recommendations, see our best teeth whitening guide, or our best whitening strips roundup for that format specifically.
