Love these, 2-3 a day and both my mouth and mind feel better
I love these, it's like getting in another brushing of the teeth mid-day without actually having to brush your teeth. Like my mouth actually feels cleaner after chewing these. Thank you for embracing what our ancestors spent thousands of years perfecting.
Marie D.
Highly recommended! I’ve bought twice! Use everyday!
It gives a clean feeling, it’s helped my teeth, strengthens jaws & teeth. Finally a pure organic gum. Haven’t chewed gum in 10+ years before finding this through TickTock then came to site to repurchase.

Quick to get it’s job done!
Very refreshing product to use! It’s not overly sweet but just enough to be a minty refreshing kick! And it does an amazing job of getting all the food taste out of my mouth after lunch so I can get back to work and not worry about my breath! Thank you for making such a natural and great product!!!

Favorite Gum
I struggle with bad breath despite good oral hygiene. normally gum gives you instant fresh breath but in the long run, the sugar and chemicals seem to make it worse. Since i’ve switched out for this my breath is better and my mouth even feels better. highly recommend. just one complaint though, please make a bulk value pack or set!

Great Natural Gum!
Was my first time ordering natural gum. Was initially skeptical but it was a great experience. Shipping was quick. The gum is very pleasant. The flavor doesn’t last long but the gum sure does. Most gum melts the longer you chew it. This one last for quite a while. Definitely enjoyed it. Will be ordering again!
Hannah S.
I love it!
I got the cinnamon, and I'm obsessed. I've been eating organic and non gmo since before I can remember, and one thing I always wished health food stores had was good gum! It would be awesome to see this in Natural grocers! The cinnamon flavor is strong and even after it goes away there's a nice earthy flavor. Can't wait to see the benefits!

INCREDIBLE PRODUCT
I’ve always wondered if there was a cleaner, safer, and beneficial gum out there and I am so glad to have seen advertisements about this one on TikTok! The care and thought that gets put into this gum is totally worth every penny. Highly, highly, HIGHLY recommend!
