Because of Covid, my six month teeth cleaning was postponed, so that I had to wait an extra four months. I assumed I would have an extra amount of tartar build-up from waiting for ten months. Instead, I had less than usual and was told I had very little, actually. The only answer had to be because of this toothpaste. That spoke volumes, in my opinion. I love the way my teeth feel all the time, now. They feel like I just got them cleaned at the dentist.
