10 Best Mouthwashes To Fight Bad Breath And Plaque

Ever had a conversation cut short because you suddenly felt self-conscious about your breath? Or maybe you brushed thoroughly, yet that fuzzy feeling on your teeth just wouldn’t go away? If that sounds familiar, a good mouthwash might be your missing puzzle piece.

Mouthwash does more than just freshen breath. The right one can break down plaque, target odor-causing bacteria, and leave your mouth feeling squeaky clean—like a post-dentist visit clean. But with shelves stacked with bold claims and colorful bottles, where do you even begin? We’ve rounded up 10 of the best mouthwashes that tackle both bad breath and plaque build-up. Let’s take a closer look at which ones actually live up to the hype.

If there were a superhero in the mouthwash world, this might just be it. Listerine Total Care doesn't stop at the breath—it targets plaque, strengthens enamel, and even helps prevent cavities. That's a full dental routine in a single swish.

Why people love it:

• Clinically proven to reduce plaque and gingivitis.

• Offers six dental benefits in one.

• Minty, but not overpowering.

One thing to note: It contains alcohol, which may not suit those with sensitive gums.

Have you seen those TikTokers rave about this green bottle? They’re not exaggerating. TheraBreath uses oxygenating compounds to neutralize sulfur-producing bacteria—the ones responsible for that dreaded morning breath.

Standout features:

• Doesn’t just mask odor; it fights the source.

• Free from alcohol, dyes, and artificial flavors.

• Doctor-formulated and safe for long-term use.

Great for: People with chronic halitosis or dry mouth.

Plaque is often the gateway to more serious issues, like tooth decay. That’s where ACT steps in. With added fluoride, this rinse focuses on cavity prevention while still helping reduce plaque and freshen breath.

What sets it apart:

• High fluoride concentration (good for enamel).

• Multiple flavor options for picky palates.

• Recommended for teens and adults alike.

Pro tip: Use it at night to let fluoride work its magic while you sleep.

Don’t let the “Pro” label scare you—it’s not just for dentists. Crest’s Pro-Health Advanced formula packs a plaque-fighting punch, even without the sting of alcohol.

Key benefits:

• Targets plaque, gingivitis, and bad breath.

• Alcohol-free with a clean mint flavor.

• Helps prevent and reverse early gum disease signs.

Who it’s for: Anyone looking for a gentle, daily-use rinse that doesn’t skimp on effectiveness.

If you’ve ever been frustrated by mouthwash that only works for 15 minutes, SmartMouth might change your game. This rinse works in two parts—one neutralizes bacteria, and the other prevents them from producing odors for up to 12 hours.

Why it’s clever:

• Keeps your breath fresh all day.

• Doesn’t burn or dry out your mouth.

• Ideal for morning and nighttime use.

Bonus tip: Many users swear by using it before bed for a fresh start in the morning.

You’ve heard of Colgate toothpaste, but their Total 12HR Pro-Shield mouthwash is equally worth attention. It provides a whole 12 hours of protection—even after eating or drinking.

Highlights include:

• Kills 99% of germs on contact.

• Alcohol-free, with a smooth finish.

• Especially useful for people on the go who can't brush often.

The best part is that it doesn't mess with your taste buds like some stronger formulas do.

Some people can’t handle the intensity of typical mouthwashes. If your mouth feels scorched after every rinse, CloSYS might be your gentler alternative.

Why dentists recommend it:

• pH-balanced and sulfate-free.

• Fights plaque and odor without irritation.

• Comes unflavored, but you can add a flavor dropper if you like.

Who should try it: People with sensitive teeth, post-surgery mouths, or dry mouth issues.

For those leaning toward natural ingredients, Tom’s of Maine offers a refreshing blend of science and simplicity. No artificial sweeteners, no synthetic dyes—just a clean rinse powered by zinc.

Why it's popular:

• Made with naturally derived ingredients.

• Tackles odor at the root with zinc chloride.

• Minty but mild.

Ideal for: Eco-conscious consumers who still want effective protection against bad breath.

If you're dealing with a serious plaque and want to feel the burn (in a good way), Listerine Ultraclean is your go-to. It reaches deep into crevices where your brush and floss might miss.

What it delivers:

• Intense plaque control.

• Long-lasting freshness.

• Proven clinical effectiveness.

Fair warning: The alcohol content is noticeable, so be prepared for that signature Listerine zing.

Sometimes, mint isn't enough. Oxyfresh blends lemon and mint with Oxygene®—a non-toxic compound that oxidizes sulfur compounds to fight bad breath at the molecular level.

What makes it unique:

• Fresh citrus-mint flavor.

• Neutralizes odor-causing compounds instead of masking them.

• Alcohol- and fluoride-free.

Best for: People who want a fresh twist on traditional mint rinses.

Still unsure which one’s your match? Think about what matters most to you:

Go for oxygenated rinses like TheraBreath or SmartMouth.

Listerine Ultraclean or Crest Pro-Health are your best bets.

ACT’s fluoride rinse is tough to beat.

CloSYS or Oxyfresh are gentle but effective.

And if you're after something that does a little of everything—breath, plaque, cavity, and gingivitis protection—Listerine Total Care or Colgate 12HR Pro-Shield offer well-rounded results.

Mouthwash isn’t a magic bullet. It works best as part of a complete oral routine—brushing twice a day, flossing daily, and getting regular checkups. But the right rinse can boost your results, especially if you’re targeting specific problems like odor or stubborn plaque.

Think of it like skincare: some people need a basic moisturizer, others need a full 5-step regime. Mouthwash gives you that customizable edge, depending on your goals. So next time you're in the oral care aisle, you'll know exactly what to reach for—and why. Your breath, your gums, and your dentist will thank you for it.
