    Love how it foams so nicely and has a nice minty taste. Did not like the taste of lavender with Sleep.

    I'm glad I tried this product out. It helps me fall asleep gently and quickly. This is a new essential part of my sleep routine. The lavendar is a tad strong, but I enjoy it. Happy brushing!

    Way better than other toothpaste tablets!

    My dental hygienist can’t stop oohing and ahhing over my teeth since I started using these tablets. They foam up so nicely compared to other toothpaste tablets. I subscribed for auto shipping because I don’t want to ever run out.

    Love the packaging!

    I already had the glass bottles, so I am thrilled with the reduced waste on this packaging.
