Great Clean Alternative to Traditional Mouthwash, LOVE this!!
Flavor Name: Mint, Size: 3.5 Ounce (Pack of 1)
I’ve been really impressed with these Boka mouthwash tablets. They’re fluoride‑free and alcohol‑free, which is exactly what I was looking for, and the hydroxyapatite is a nice bonus for supporting enamel without the harshness of traditional mouthwashes. The tablets dissolve easily, the flavor is refreshing without being overpowering, and there’s no burning sensation at all. Do NOT chew and swallow like I did the first time. Chew, get salva going and swish. My teeth never felt so clean!!!
I also love that they’re travel‑friendly and cut down on plastic waste compared to big bottles. My breath feels fresh, and my mouth feels clean without that chemical aftertaste. If you’re trying to switch to a cleaner, gentler oral‑care routine, these are a great option.

Tasty, effective, and helpful against thrush
Flavor Name: Citrus Mint, Size: 3.5 Ounce (Pack of 1)
This is a good plastic-free, portable form of mouthwash. Pop one or two tablets in your mouth, chew well, add a little water if your mouth is particularly dry (mine is), swish, and spit. That's it. They don't burn like regular mouthwash, and they leave a nice flavor that isn't overpowering and that lasts longer than other mouthwashes have for me. It's a balanced flavor, if that means anything to you - basically, my mouth somehow feels right afterwards.
I was skeptical about the claim that these improve the mouth microbiome, but they've virtually eliminated the thick white layer (presumably thrush) that I've been fighting to clear off my tongue forever. So, yeah, these are definitely a winner.

More like a mint candy than mouthwash.
Flavor Name: Mint, Size: 3.5 Ounce (Pack of 1)
Hard to describe this product. Does it work like your typical mouthwash? No. Does it leave your mouth feeling minty and fresh? Yes, to a certain extent. Would I consider this an alternative to mouthwash on a consistent basis? No, it's ok for traveling because it's easy to transport.
When you chew this tablet, it has the texture and feel of a traditional mint. It's chalky and breaks up easily.
