The 13 Best Whitening Mouthwashes to Brighten Your Smile

I drink a lot of coffee. Like, a whole lot. And while I love the caffeine boost, I don’t love the dull, yellowish tint it leaves on my teeth. Whitening strips can be a pain, and professional treatments are expensive. So, I started looking for the best whitening mouthwash to add to my routine.

A good teeth whitening mouthwash isn’t going to give you blindingly white teeth overnight. That’s not what they’re for. But they are fantastic at lifting away daily surface stains from things like coffee, tea, and red wine, gradually brightening your smile over time.

I tried a bunch of them to see which ones actually work, which ones taste decent, and which ones don’t make my sensitive teeth scream. Here are my top picks to help you get a brighter, healthier smile without a ton of effort.

 

 

Our Top Whitening Mouthwashes

Colgate Optic White Whitening Mouthwash

This one costs about $9. It’s a classic for a reason and one you’ll hear dentists recommend a lot.

The 2% hydrogen peroxide formula is no joke; it really gets in there and lifts surface stains. I found that when I used it with the matching Optic White toothpaste, I started seeing a real difference in a few weeks. It feels powerful but didn’t cause any irritation for me.

The Downside: You have to be patient with this one. It’s not an overnight fix and requires consistent, daily use to see results.

 

 

Crest 3D Glamorous White Mouthwash

For around $8, Crest is the king of over-the-counter whitening, and this mouthwash shows why. If you want to see a change fast, this is your bottle.

It promises visible results in just 7 days, and I believe it. The foaming action feels like it’s really working to scrub away stains. The minty flavor is fresh without being overwhelming, and my mouth felt clean for hours.

The Downside: That “foaming action” can be a little intense if you’re not expecting it. It definitely expands in your mouth.

 

 

ACT Whitening + Anticavity Fluoride Mouthwash

This is a great deal at just $6. If you have sensitive teeth or gums, I’d point you toward this one immediately.

It’s alcohol-free, so you don’t get that harsh burn or dry mouth feeling. It gently foams to lift stains while also hitting your teeth with fluoride to strengthen enamel and prevent cavities. The gentle mint flavor is really pleasant, too.

The Downside: A little goes a long way. If you use too much, it expands a lot, so you have to be careful with your pour.

 

 

Listerine Healthy White Fluoride Mouthwash

You can usually find this for about $7. This is for people who want whitening but are also serious about enamel health.

It has that classic, intense Listerine feel, but it’s working double-duty. The formula removes stains while the fluoride gets to work restoring weak spots in your enamel. My teeth definitely felt stronger and looked a bit brighter after a couple of weeks.

The Downside: It contains alcohol, which gives it that signature “burn” and can be really drying for some people.

 

 

TheraBreath Whitening Fresh Breath Oral Rinse

At around $9, this one is all about getting a dentist-clean feeling. It’s fantastic for breath, first and foremost.

It was created by a dentist and doesn’t use peroxide, so it’s incredibly gentle. The whitening action comes from its ability to prevent new stains from forming while gently lifting old ones. I love how it makes my breath feel genuinely fresh without any burn at all.

The Downside: The whitening effect is much slower and more subtle compared to formulas with hydrogen peroxide.

 

 

Supersmile Whitening Pre-Rinse

This is a splurge at $20. But it’s not a mouthwash—it’s a pre-rinse, which is a whole different approach.

You swish with this *before* you brush to loosen up stains. The combination of hydrogen peroxide, baking soda, and malic acid primes your teeth so your whitening toothpaste can work even better. It feels like you’re giving your brushing routine a serious power-up.

The Downside: It’s expensive, and it’s an extra step in your routine that’s easy to forget.

 

 

Lumineux Whitening Mouthwash

Priced around $8, this is my top pick for anyone who wants a completely natural option for sensitive teeth.

It’s peroxide-free and instead uses a blend of coconut oil, sage oil, and aloe vera. It feels so gentle and actually leaves my mouth feeling moisturized, not stripped. It won’t give you dramatic results, but it does offer a noticeable, gentle brightening without any harsh chemicals.

The Downside: The whitening effects are much milder than chemical-based formulas. It’s more of a gentle polish.

 

 

Amazon Basics Whitening Anticavity Mouthwash

You can’t beat the price at $5. This is a straightforward, no-frills option that flat-out works.

It has hydrogen peroxide to whiten and fluoride to fight cavities, checking all the essential boxes. The minty flavor is clean and simple. If you just want an effective whitening mouthwash without paying for a brand name, this is the one to get.

The Downside: The packaging is extremely basic and doesn’t look great on the counter, if you care about that sort of thing.

 

 

Crest Pro-Health Advanced Extra Whitening Mouthwash

For about $8, this mouthwash tries to do it all. It’s for people who want whitening plus a ton of other oral health benefits.

It’s alcohol-free but still feels like it’s killing germs and fighting plaque. It also strengthens enamel, freshens breath, and, of course, whitens. I think of it as a great all-in-one mouthwash with an added whitening boost.

The Downside: To get the best whitening results, you really need to use it with the corresponding Pro-Health toothpaste.

 

 

hello Activated Charcoal Whitening Mouthwash

This unique option costs around $7. If you’re into natural ingredients and the charcoal trend, you’ll love this.

It’s vegan and uses activated charcoal from sustainable bamboo to absorb impurities and gently whiten. It turns your mouth black while you’re swishing, which is weirdly fun. The fresh mint and coconut oil flavor is surprisingly good, and it leaves my teeth feeling super clean.

The Downside: The charcoal can sometimes leave a very faint grey residue near the gum line that requires a little extra rinsing.

 

 

Moon Stain Prevention Whitening Mouthwash

This one is about $8 and definitely wins for best-looking bottle. It’s perfect for keeping stains away.

It’s designed more for maintenance than for heavy-duty whitening. If you’ve just whitened your teeth or want to keep your daily coffee habit from undoing your hard work, this is a great choice. The antioxidant blend and gentle brighteners keep new stains from setting in.

The Downside: It’s focused more on preventing future stains than removing deep-set, old ones.

 

 

The Dirt Oil Pulling Mouthwash

At $22, this is a very different kind of product. It’s for people who are into oil pulling or want a totally different routine.

Instead of a quick 60-second rinse, you swish this MCT oil-based formula for 5 to 20 minutes. It feels strange at first, but it leaves your mouth feeling unbelievably clean and moisturized. The cinnamon and clove oils naturally freshen breath and help brighten your teeth over time.

The Downside: It’s a serious time commitment, and the oily texture is definitely not for everyone.

 

 

Tom’s of Maine Simply White Whitening Mouthwash

A solid natural choice for about $6. Tom’s is a brand you can trust for gentle, effective formulas.

This mouthwash uses zinc citrate, which is clinically proven to whiten by preventing tartar buildup, where stains often cling. It’s alcohol-free and has a mild, clean taste that isn’t overpowering. It’s a great everyday mouthwash for someone who wants subtle, natural brightening.

The Downside: The whitening is very gradual. Don’t expect dramatic changes with this one.

 

 

What I Learned

Finding the best whitening mouthwash really depends on your goals. If you want speed, go for a hydrogen peroxide formula like Crest or Colgate. If you have sensitive teeth, something gentle and alcohol-free like ACT or Lumineux is a much better bet.

No matter which one you choose, consistency is everything. Using it every single day is how you’ll see results. Pair it with a good whitening toothpaste, and you’ll be on your way to a brighter smile without much extra work.
