Bite dot com slash max is offering 20% off of their first subscription order. They use hydroxyapatete, which has been shown in some studies to be just as good at remineralizing your teeth as fluoride. Also good for sensitivity and non-toxic. I love Bite, no plastic tube, no messy paste. They are carbon neutral, cruelty free, all the good things. They check all the boxes. And I just love that you get to crush this little tablet and brush with it. It's super fun. 12 year old me is psyched.
