The TL;DR on Toothpastes for Bad Breath

Flavor: Mild Mint

TheraBreath is one of the best toothpastes for bad breath, and it's a top-selling on Amazon to boot. Founded by a dentist who wanted to help his own daughter conquer her bad breath, this paste uses oxygenation to attack bad breath at the source (the release of oxygen disrupts the ability of harmful bacteria to grow and colonize), while fluoride helps control plaque, tartar, and cavities. Also nice: It's free of artificial colors and flavors and is certified vegan and kosher. But if you love the feeling of foamy, lathered toothpaste, the TheraBreath toothpaste may not be your match. It turns to liquid quickly while in use.

Flavor: Radiant Mint

Your toothpaste needs to do it all — and even if you’re looking for toothpaste for bad breath specifically, you probably also want to protect your teeth against cavities. The Crest 3D White Toothpaste wins high praise for strengthening enamel, removing surface stains, and not irritating sensitive teeth, making it an all-around winner. Although this toothpaste claims to remove up to 80 percent of surface stains and whiten teeth, it didn't totally live up to the whitening hype. If whitening your teeth with toothpaste and fixing bad breath is your goal, we’d recommend Arm & Hammer Advance White Extreme Whitening Baking Soda & Peroxide Toothpaste (more on that below).

Flavor: Fresh Wave

If you have sensitive teeth or gums, consider this toothpaste that binds to dentin (the layer beneath your enamel) to protect against hot and cold substances. On top of being great for those with sensitivities, it also promises fresh breath, fighting against odor-causing bacteria and leaving you with a minty clean feeling.

Flavor: Clean Mint

Numbers don’t lie: This toothpaste offers a 10x longer-lasting cool than the next leading fluoride toothpaste. Made with fluoride and packed with hundreds of mini breath strips, this toothpaste whitens and removes stains, and also fights cavities and bad breath-causing bacteria on teeth, tongue, cheeks, and gums. However, this toothpaste seems to cover up bad breath, rather than knock it out at its source by targeting food particles or molecules associated with bad breath.

Flavor: Clean Mint

This Arm & Hammer toothpaste fights bad breath and whitens teeth in just six weeks, but gently (read: your teeth won’t feel overly sensitive or irritated after using). Baking soda helps remove soft plaque and light staining, and it also has antibacterial properties to help prevent your teeth from decay. Meanwhile, hydrogen peroxide is the active ingredient for tooth whitening. (Note that because the hydrogen peroxide is a low percentage of active ingredients, it'll take some time to see results). But if you’re picky about taste, this might not be the toothpaste for you. The flavor is slightly odd and not the minty taste you're probably used to. However, this toothpaste is a far better and safer alternative to DIY viral TikTok teeth-whitening hacks.

Flavor: Mint Blast

If you love the feeling of lathering up your teeth, this foamy toothpaste for bad breath delivers. The Aquafresh Extreme Clean active foam reaches between teeth to remove plaque and food debris and maintain good oral hygiene by killing germs, fighting plaque, and deep cleaning. The added foam also gets way back in your mouth, along your gums, and at the back of your tongue where foul-smelling bacteria can linger. However, if you have sensitive teeth, this toothpaste might be a little bit strong for you.

Flavor: Lemon Mint

Made without fluoride, this toothpaste fights bad breath at the source, thanks to antioxidant-packed essential oils, zinc, and oxygene (an ingredient that's essentially stabilized chlorine dioxide, which disrupts bacterial colonization and helps disinfect), which control plaque and freshen breath. Multiple customers say that their dentists actually recommended this paste specifically to treat bad breath, canker sores, and more. An independent study even found that this toothpaste has shown beneficial long-term results at helping to reduce plaque and helping to strengthen gum tissue.However, be warned: Dentists typically recommend toothpaste with fluoride in it to prevent tooth decay and other dental hygiene issues.

Flavor: Clean Mint

Coffee fiends, this toothpaste might be the solution to your bad breath and stained teeth. Boasting a unique blend of zinc and essential oils, this toothpaste neutralizes bad breath and oral malodor, while removing stains and aiding in the prevention of dental decay. However, this toothpaste for bad breath is more expensive than other drugstore brands, and it may dry out your mouth.
