I absolutely LOVE my Boka kit! The floss, the toothpaste, and electric toothbrush! Even the handheld toothbrush! If you try and set it down, it never lays on it's side, it bounces back to standing straight on the counter so the bristles never touch the counter! How cool is that!? My teeth had some major sensitivities when I began using Boka, switching from a Sonicare. Sonicare seemed to have too rough of bristles and speed setting that would just hurt my teeth and gums. The sensitivities in my teeth have drastically diminished since using Boka. I appreciate that Boka is much more mindful of what is in their product, and began looking to switch after reading up on the wax coating most floss has-like Oral B, etc...contains a forever chemical that never breaks down...and we put that in our mouth?! No thanks! Thank you Boka for transforming my oral care routine into something more enjoyable!
