Birchbox Breakdown

If you miss spending your summer days with nothing but time to kill and a packet of Pop Rocks, then you’ll be happy to find these Effervescent Breath Crystals, which attack halitosis with the ferocity of that sweet, crackling candy. The science rests on a mix of bacteria-fighting ingredients that, when in contact with germ-filled teeth and gums, erases the effects of embarrassing odors caused by things like coffee, onions, and garlic with a series of mini-mouth explosions.

How it Works

Unlike gum and breath mints, which only mask bad breath, these teeth-cleaning crystals pack zinc and IsoVoxy to kill odor-causing bacteria. Once dissolved, they leave a fresh scent courtesy of natural peppermint flavors.

How to Use

Pour the contents of an individual pack into your mouth and swish the crystals around, rubbing them against teeth and tongue. Let them dissolve or swallow and enjoy peppermint-fresh breath!

Peppermint: Isomalt, Carbon Dioxide, Xylitol, Natural Peppermint Flavor, Zinc Gluconate, Sunflower Oil, Sucralose.

Spearmint: Isomalt, Carbon Dioxide, Xylitol, Natural Spearmint Flavor, Zinc Gluconate, Sunflower Oil, Sucralose.

Lemon: Isomalt, Carbon Dioxide, Xylitol, Natural Lemon Mint Flavor, Zinc Gluconate, Sunflower Oil, Sucralose.

Honey: Isomalt, Carbon Dioxide, Xylitol, Natural Honey Mint Flavor, Zinc Gluconate, Sunflower Oil, Sucralose.

Loved these -- it was basically like freshening your breath with candy. Highly recommend for a quick refresher with a nostalgic bent.

Fun!

These are basically like pop rocks for adults. Fun alternative to a basic breath mint and easy to carry around in your purse. It might be a good conversation starter too..

Interesting twist on pop rocks
Sampled

Refreshing and didn't leave a weird aftertaste. It's basically pop rocks with a fresh purpose. The freshness didn't last as long as chewing gum.

Eeehhhh

Not a huge fan of these breath crystals. I was excited about these and kept them in my car for emergency occasions. They always seemed to leave a really bad taste in my mouth. I was not confident that I truly had fresh breath.

Pop rocks for good breath
Sampled

These weirded me out a bit. They are just like pop rocks but improve your breath. I couldn't get over the popping. Not for me, but if you like pop rocks, you'll love it.

These were pretty cool and left my breath fresh. I wouldn't say my teeth felt cleaner but that's cool. I would love to keep a few of these at work.

Strange but pretty fun

These were kind of strange but I actually enjoyed trying them. Not sure if it is something I would spend much money on, but definitely fun to try and tasted good. Effective too!
