Can’t decide on just one flavor? Get all four in the Effervescent Breath Crystals with IsoVoxy multipack.

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!

Total gimmick.
Purchased

All these did was clump together and get stuck in my teeth! They were obnoxiously difficult to swish around in my mouth, and I felt disgusting afterwards and in no way as if my mouth was any cleaner. Don't waste your money!

Pop Rocks for big kids
Purchased

I love the peppermint flavor. Works well when you need a quick breath fresher. The individual packets make a nice stocking stuffer.

A little pricey
Purchased

I got this in the Honey Mint version, and it tastes a little weird. I've heard the other flavors are better. It's also a little pricey, but nice if you have money to spend and want a breath freshener and poprocks duo...

I think I'm sticking to gum/mints.

Pleasant surprise. Much better than gum or harsh sprays. Love the intensity of the pops and it tastes good too!

Yummy
Purchased

I really enjoyed the pop rocks feel of this product. Although a little pricey for the fun factor. Had to hide them from my husband.

It was kind of overwhelming putting the whole packet in my mouth so I only used half. I decided to use the other half for later however when I did they no longer worked. The pop-rock like experience was gone. The breath freshening part still worked though.

Awesome and fun
Purchased

These little pop rocks are great to carry in your purse for fresh breath in between brushings, or just an extra kick after brushing. Each pack has multiple uses, so they are actually pretty economical. They are great for people who don't want to chew gum or have a mint. I will continue to stock this at my house

Reminded Me of Pop Rocks

Such a neat idea! If I can't have my toothbrush with me it's nice to have something small in my purse. While I would probably prefer a piece of gum, I tend to chomp which is really unprofessional, especially in meetings. I'd recommend these little packets for on-the-go action.
