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 stain-dissolving surfactants. 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 six that balance stain-fighting performance with everyday usability. 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, enzymes, coconut oil)?
- 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.
Crest Pro-Health Advanced Extra Whitening Mouthwash
Crest Pro-Health Advanced Extra Whitening Mouthwash
Best for: Most people who want an effective, alcohol-free whitening rinse
- Alcohol-free formula for comfortable daily use
- Helps prevent stains, fight cavities, and strengthen enamel
- Energizing Mint flavor praised in 20,000+ reviews
- 32 oz bottle for extended use at under $8

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 Pro-Health uses surfactants and polishing agents to help lift and prevent surface stains, while also delivering fluoride for cavity protection and enamel strengthening. It’s a multi-benefit formula that lets you combine whitening with your daily oral care rather than adding a separate step.
Reviewers consistently highlight two things: the taste is pleasant without being overwhelming, and the alcohol-free formula doesn’t cause the burning sensation common with traditional rinses. 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
- From Crest’s Pro-Health line — their clinically-oriented product tier
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
This isn’t a peroxide-based whitener, 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 uses hydrogen peroxide. 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 hydrogen peroxide-based whitening with clinical backing
- 2% hydrogen peroxide — among the highest OTC mouthwash concentrations
- Icy Fresh Mint flavor with no alcohol burn
- 3-pack (16 oz each) for excellent per-ounce value
- Colgate's Optic White clinical whitening line
✓ Free shipping with Prime · ✓ Amazon's price guarantee · Affiliate link
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 found that peroxide-based products can meaningfully reduce tooth discoloration when used consistently.
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 16 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. The entire Optic White line is Colgate’s clinical whitening tier, 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 16 oz bottles per package for extended supply
- Part of Colgate’s Optic White clinical 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 is safe for daily use according to the ADA, 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 oil pulling and whitening combined in one step
- Dual-chamber bottle mixes hydrogen peroxide with coconut oil at each pour
- Combines modern whitening with traditional oil pulling in one product
- Alcohol-free, fluoride-free formulation
- Wild Mint flavor with 8,400+ positive reviews
✓ Free shipping with Prime · ✓ Amazon's price guarantee · Affiliate link
Why We Recommend It
GuruNanda’s Dual Barrel design is unlike anything else in this category. The bottle has two separate chambers — one containing hydrogen peroxide and the other containing coconut oil — that mix together only when you pour. This keeps the hydrogen peroxide fresh and active until the moment of use, rather than gradually degrading in a pre-mixed formula.
The concept merges two approaches to oral care: hydrogen peroxide whitening and oil pulling, the Ayurvedic practice of swishing oil in your mouth. While the clinical evidence for oil pulling is limited, a 2016 systematic review in the Journal of Clinical and Diagnostic Research found that oil pulling with coconut oil may help reduce plaque and gingivitis markers. Combined with the established whitening power of hydrogen peroxide, it’s an interesting two-in-one approach.
With over 8,400 reviews and a 4.6-star rating, the user reception has been strong. Reviewers frequently mention that the oil pulling component makes the rinse feel more moisturizing and less drying than typical peroxide mouthwashes, and many report visible whitening improvement within a few weeks of daily use.
Key Features
- Dual-chamber design keeps hydrogen peroxide fresh until each use
- Combines hydrogen peroxide whitening with coconut oil pulling
- Alcohol-free and fluoride-free
- 20 fl oz bottle at under $10
- “Safer Chemicals” badge from Amazon for ingredient transparency
Who It’s Best For
If you’re already interested in oil pulling but find it inconvenient (traditional oil pulling means swishing coconut oil for 15-20 minutes), GuruNanda packages the concept into a standard 60-second rinse. It’s also a strong choice if you’ve found other peroxide mouthwashes too harsh or drying — the coconut oil component genuinely softens the experience. People who prefer natural-leaning products but still want peroxide-level whitening will appreciate the hybrid approach.
Potential Downsides
The dual-barrel bottle is clever but can be slightly awkward to pour evenly from both chambers. Some reviewers note that the oil component gives the rinse a slightly thicker texture than conventional mouthwash, which takes some getting used to. As with any peroxide-based product, temporary sensitivity is possible. The oil pulling benefits, while promising, have less clinical backing than straightforward peroxide whitening.

Listerine Ultraclean Whitening Mouthwash
Listerine Ultraclean Whitening Mouthwash
Best for: Listerine loyalists who want whitening benefits added to their routine
- Combines Listerine's essential oil antiseptic with whitening technology
- Clinically proven to fight tartar and reduce plaque above the gumline
- Clean Mint flavor in the classic Listerine style
- Fluoride-free formula focused on antiseptic and whitening action
✓ Free shipping with Prime · ✓ Amazon's price guarantee · Affiliate link
Why We Recommend It
Listerine has been a dental professional staple for over 140 years, and the Ultraclean Whitening variant adds stain-fighting technology to their proven antiseptic formula. The whitening mechanism works through a combination of surfactants that help dissolve and prevent surface stains, layered on top of Listerine’s four essential oils (eucalyptol, menthol, methyl salicylate, and thymol) which are clinically proven to reduce plaque and gingivitis.
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 validated by decades of clinical research and carries the ADA Seal of Acceptance for plaque and gingivitis reduction. 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)
- Stain prevention and surface stain removal technology
- Clinically proven to reduce plaque above the gumline
- Clean 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 Crest Pro-Health (#1) or Lumineux Complete Care (#6) 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
✓ Free shipping with Prime · ✓ Amazon's price guarantee · Affiliate link
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.
The whitening approach uses a combination of stain-dissolving agents and enamel-safe polishing technology. 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.
Reviewers are enthusiastic about the flavor profile and the noticeable results. 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 (~$16 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 hasn’t accumulated the decades of clinical validation that Listerine or Colgate’s core lines carry. Some users may find the difference between this and the more affordable Crest Pro-Health Advanced doesn’t justify the price premium.

Lumineux Complete Care Mouthwash
Lumineux Complete Care Mouthwash
Best for: People who want a gentle, natural rinse without peroxide, alcohol, or fluoride
- Peroxide-free, alcohol-free, fluoride-free, SLS-free
- Dentist-formulated with Dead Sea salt, aloe vera, and essential oils
- Backed by 60+ clinical and laboratory studies
- 16 oz bottle designed for sensitive teeth and gums
✓ Free shipping with Prime · ✓ Amazon's price guarantee · Affiliate link
Why We Recommend It
Lumineux takes a fundamentally different approach from every other product on this list. Rather than targeting whitening with hydrogen peroxide, it focuses on overall oral health using a short, clean ingredient list — Dead Sea salt, organic aloe vera juice, French essential oils, and non-GMO xylitol. The idea is that a healthier mouth naturally looks better, and that gentle daily care prevents the staining conditions (dry mouth, plaque buildup, gum irritation) that dull teeth over time.
The brand was created by dentist Dr. Kourosh Maddahi and claims over 60 clinical and laboratory studies supporting its formulations. The formula is free from alcohol, fluoride, SLS, artificial dyes, and artificial colors — making it one of the gentlest daily rinses available. Lumineux is certified non-toxic by Made Safe, an independent organization that screens products for known harmful substances.
At 4.5 stars across 2,000+ reviews, users consistently praise the mild mint flavor, the lack of burning or irritation, and noticeable improvements in breath freshness. This isn’t a product that promises dramatic whitening — it’s the pick for people who believe the best approach to a brighter smile is a healthier mouth, achieved without harsh chemicals.
Key Features
- Dead Sea salt, organic aloe vera, French essential oils, and xylitol
- Certified non-toxic by Made Safe
- Dentist-formulated (Dr. Kourosh Maddahi) with 60+ supporting studies
- Free from peroxide, alcohol, fluoride, SLS, artificial dyes, and artificial colors
- 16 oz bottle at a mid-range price point
Who It’s Best For
Lumineux is the right choice if you have sensitivity to hydrogen peroxide, prefer clean-ingredient products, or simply want to avoid peroxide in your daily routine. It’s especially well-suited for people who have experienced irritation or sensitivity from other whitening mouthwashes — the gentle formula is designed to be comfortable for daily use even with sensitive teeth and gums. If you prioritize oral health over aggressive stain removal and want a rinse that fits a natural oral care philosophy, this is your pick.
Potential Downsides
This is not a dedicated whitening product, so don’t expect the same level of stain removal you’d get from a 2% hydrogen peroxide rinse like the Colgate Optic White. Lumineux works by supporting overall oral health rather than actively bleaching stains — any brightening effect is gradual and subtle. It’s also a single 16 oz bottle at around $15, making it one of the more expensive per-ounce options in this roundup. With around 2,000 reviews, it has a smaller user data pool than our other picks, though the 4.5-star average is strong.

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 (like Crest Pro-Health and Lumineux) use surfactants, polishing agents, or natural ingredients to support oral health and help prevent surface stains from building up.
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 well within the safety range established by the ADA, and research supports its effectiveness for surface whitening.
Choose non-peroxide if you have sensitive teeth, prefer gentler products, or want a multi-benefit rinse where whitening is one feature among several (cavity protection, breath freshening, plaque reduction).
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.
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 concentrations of 1.5-3%, hydrogen peroxide mouthwash is generally considered safe for daily use. The ADA has evaluated peroxide-based whitening products and granted the Seal of Acceptance to those meeting safety and efficacy standards. 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 at standard concentrations (1.5-2% hydrogen peroxide) have not been shown to damage healthy enamel when used as directed. A 2013 review in Dental Materials Journal found that low-concentration peroxide whitening products are generally safe for enamel. That said, if you 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 Whitening (#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.
