Mouthwash can be an excellent way to clean your mouth and freshen your breath, but standard mouthwashes can contain potentially irritating ingredients. “Alcohol is drying to the oral cavity,” Dr. Tiffanie Garrison-Jeter, D.M.D., a dentist at Definition Dental Studio tells Byrdie. “And a dry mouth makes an environment that’s more prone to getting cavities.” Dr. Garrison-Jeter says other common mouthwash ingredients, like artificial flavors, synthetic dyes, and parabens can also be irritating.

Byrdie Researched & Approved

Our top pick for natural mouthwashes is the TheraBreath Fresh Breath Oral Rinse, which uses oxygen to kill bad-breath germs for fresh breath that lasts for 24 hours. If you're on a tight budget, we also love the Lumineux Oral Essentials Whitening Mouthwash, which whitens while still being gentle on teeth and gums.

These ingredients may not cause a problem for everyone. But if you find them irritating—or if you just want to cut down on artificial ingredients—natural mouthwashes may be a great option. Natural mouthwashes tend to be partially or entirely made of natural ingredients, and they’re often free from alcohol and other potential irritants. Of course, some natural mouthwashes are more effective than others, so Dr. Garrison-Jeter recommends talking to your dentist before trying a new product—and keeping up with your biannual check-ins to make sure everything’s working the way it should. 

To compile this list, we spent hours researching the best natural mouthwashes on the market, evaluating them based on their active ingredients and claims outside of freshening your breath - whether that be whitening or gum protection. Alongside expert recommendations from a practicing dentist and after looking through dozens of formulas, we landed on these top-rated picks.

Read on to see the best natural mouthwashes available today.

Best Overall: TheraBreath Fresh Breath Oral Rinse

4.7
TheraBreath Fresh Breath Oral Rinse
What We Like
  • Works with oxygen

  • Keeps breath fresh for hours

  • No burning or stinging

What We Don't Like
  • Flavor may not be for some

Who else recommends it? Healthline and The Strategist both picked TheraBreath Fresh Breath Oral Rinse.

What do buyers say? 1,800+ Walmart reviewers rated this product 4 stars or above.

TheraBreath’s Fresh Breath Oral Rinse is widely beloved for its ability to combat bad breath. And the good news is: It doesn’t use alcohol to get the job done. Instead, the mouthwash harnesses the power of oxygen—yes, oxygen—to cut down on stink. Of course, oxygen isn’t an ingredient in the mouthwash, but OXYD-8, a compound that produces oxygen, is. Since the germs that cause bad breath are anaerobic, they can’t survive in an oxygen-rich environment. So, according to the brand, one quick swish of TheraBreath should give you fresh breath for up to 24 hours—no alcohol required.

Reviewers can attest to this claim, with many noting that it eliminated their morning breath and kept their mouth feeling fresh all day. They also loved that it didn't have a strong taste, and it didn't burn their gums—as some mouthwashes with alcohol can do.

Active Ingredients: OXYD-8 | Size: 16 fl. oz. | Flavor: Mint

Since hydrogen peroxide is a chemical, it’s not the kind of thing you’ll find in most natural mouthwashes. But since it promises to whiten your teeth, there’s a reason you might want some in your go-to oral rinse. Lumineux’s Oral Essentials Teeth Whitening Mouthwash is alcohol-free, fluoride-free, and preservative-free—and it’s all-natural except for the hydrogen peroxide. So you can enjoy the potential teeth-whitening benefits of hydrogen peroxide without exposing yourself to other chemicals you’d rather avoid. Not to mention that it's under $10, which makes it a great go-to.

What We Like
  • Mouth feels refreshed

  • Keeps breath fresh for hours

If you’re looking for a natural mouthwash that comes equipped with fluoride, Tom's of Maine’s Natural Fluoride Mouthwash is a solid choice. The alcohol-free formula can help combat cavities and strengthen your teeth, and it boasts a minty flavor that promises to leave your breath feeling fresh for hours.

The mouthwash also contains soothing coconut oil for good measure.

Meet the Expert

Dr. Tiffanie Garrison-Jeter, D.M.D., is a dentist at Definition Dental Studio in Nolensville, Tennessee.

What to Look for in a Natural Mouthwash

Ingredients

Reading the label might seem tedious, but it’s basically always worth the effort. Some natural mouthwashes are loaded with natural ingredients, but they’re not actually all-natural. And if there are certain ingredients you’re hoping to avoid, you’ll want to double-check to make sure they haven’t snuck in. Dr. Garrison-Jeter says to be sure also to read the fine print, as some products will only list the main ingredients in bold. “It’s crucial for those with severe allergies to check the label in its entirety to avoid adverse reactions,” she adds.

Flavor

Mouthwash is the kind of thing you’re supposed to use every day, so you want to make sure you like the way yours tastes. Some natural mouthwashes boast classic mint flavors, while others taste like cinnamon—and some others even taste like fruit.

Additives

Just like standard mouthwashes, natural mouthwashes are available in different variations—and with different added ingredients. If you’re looking for a natural mouthwash that can also remove surface stains from your teeth, Dr. Garrison-Jeter suggests using a formula with hydrogen peroxide. “It’s the active ingredient in professional whitening products that gives you the least amount of sensitivity after use,” she says. Alternatively, if you’re looking to prevent tooth decay, she suggests a natural formula that contains fluoride. To avoid an acidic mouth pH (which leads to weakened enamel, and thus, cavities), she recommends baking soda. “It will neutralize that acid produced by the foods and beverages you consume,” she said.

FAQ
  • Is natural mouthwash better than conventional mouthwash?

    Many dentists agree that traditional mouthwashes containing alcohol can dry out the oral cavity, irritating tissues. An alcohol-free rinse can help keep your mouth feeling fresh without any irritation or that signature burning sensation.

  • What is an alternative to natural mouthwash?

    There are several mouthwash home remedies that devotees swear by, but check with your dentist before trying one yourself. Popular mouth rinses include salt water, apple cider vinegar diluted with water, baking soda, water infused with lemon, and oils, like peppermint oil. Take extra caution with acidic substances like apple cider vinegar and lemon, because they have the potential to erode tooth enamel.

  • Which natural mouthwash is best for receding gums?

    If you're experiencing gum sensitivity, receding gums, or gingivitis, you may want to use a gentle mouthwash to help avoid further irritation to the gums. Many of the products on this list are suitable for sensitive gums, particularly The Natural Dentist Healthy Gums Mouth Rinse. You may want to take extra caution to avoid alcohol, which dries out gums.
