Butterly gifted me TheraBreath Whitening Oral Rinse (SDM) in Dazzling Mint, in exchange for my honest review. First off, I love the fun, sparkly silver bottle TheraBreath Whitening comes in. It has a refreshing,sweet minty taste, leaving my mouth feeling clean, and my breath extra fresh. I love that TheraBreath is founded by dentist - Dr. Harold Katz. TheraBreath Whitening whitens teeth without peroxide, using naturally sourced stain fighting enzymes. I have noticed whitening results myself, and love that TheraBreath removes stains and prevents future staining. It is non-burning, and contains no dyes, colours, alcohol, parabens or SLS/sulfates. Therabreath is certified and inclusive, kosher, halal, gluten free, and vegan. It is the #1 fastest growing mouthwash brand in Canada. I feel like since using this product my mouth hasn’t ever felt so clean, and my teeth haven’t ever looked so white.

No sting, no peroxide

TheraBreath came up with a whitening oral rinse. They are famous for non-burning, no alcohol, gentle formula so it doesn't sting. And now they add whitening to its line without peroxide. GV, vegan, kosher too. Time to show off those silvery cool white teeth.

TheraBreath Whitening Oral Rinse Review: A Minty F

If you’re like me, you’ve probably tried a dozen whitening mouthwashes that promise Hollywood-level brightness but leave your mouth feeling like it survived a chemical fire. Enter TheraBreath Whitening Oral Rinse - a cult-favorite product that claims to whiten without peroxide and keep breath fresh for hours. But does it live up to the hype? Let’s break it down.

Instead of harsh peroxide, this rinse uses natural enzymes (papain and glucose oxidase) to help lift stains. After a couple of weeks of use, I noticed my teeth looked a little brighter, especially where coffee had left its mark. No sensitivity, which is a huge plus.

2. Long-Lasting Freshness – The alcohol-free formula keeps breath fresh for hours. I tested it after a garlic-heavy meal, and it actually held up—no awkward mint-garlic combo lingering around.

3. No Weird Aftertast – Some whitening rinses leave a strange chemical taste, but this one just feels clean and fresh. Even my partner, who hates mouthwash, didn’t mind using it.

Wait at least 30 minutes after rinsing before eating or drinking to let the whitening enzymes work.
- Since it doesn’t contain fluoride, I recommend using it alongside a fluoride toothpaste for extra cavity protection.

I’d give this a 4.5/5. It’s a great option if you want a gentle, effective whitening rinse that also keeps your breath fresh. If you’re looking for dramatic whitening fast, you might need something stronger, but for everyday use, this is a winner.

Great for teeth, breath, & gums!

The taste is mild, clean, and a welcome change from other strong, alcohol-based mouthwashes, making it easy to use.
I appreciated that it's free from artificial colors and flavors, which suits my overall health goals. Overall, TheraBreath was effective at whitening my teeth, freshened my breath, reduced gum inflammation, and since it is made with quality ingredients, I highly recommend it for anyone looking to improve their oral hygiene.
