It works, but rinse and spit
Great for at home but not on the go. Definitely need to rinse and spit after a while. Does work though

Perfect for Travel — Amazing Foam, Great Taste, and Long-Lasting Freshness
Flavor Name: A Coconut+Green Tea+Peach
These Popboom mouthwash tablets seriously exceeded my expectations. They foam up really well, much more than other tablets I’ve tried, and they leave my mouth feeling clean and refreshed without that harsh, overpowering burn you get from liquid mouthwash. It’s a really nice break from traditional toothpaste and works great for bad breath, even hours later.
As someone who travels frequently, this product is an absolute must-have. The tablets are compact, lightweight, and spill-proof, so I can throw them in any bag or pocket without worrying about leaks. They’re perfect for situations when you don’t have access to water but still want fresh breath—just pop one in and you’re good to go.
Flavor-wise, they’re fantastic. Coconut is hands-down my favorite, and I also tried the trio pack to sample different options. Peach was enjoyable, while matcha wasn’t really my thing (I’ll be giving that one away), but overall the flavors are fresh, pleasant, and not overwhelming. These definitely foam up better than most similar products on the market.
I also love how convenient they are—no bulky bottles, no mess, and nothing heavy to carry around. The size is perfect, the taste is great, and I find myself reaching for them throughout the day. I’ve already reordered and will continue to keep these stocked.
If you haven’t tried these yet and you’re always on the go, what are you waiting for? These are a game-changer for travel, work, or anytime you need quick, effective mouth freshness.

These are so handy to keep in my purse and I like all of the flavors. They really help make my whole mouth feel cleaner, not just my teeth.
