This toothpaste doesn’t just have hydroxyapatite, but also coconut oil and another important ingredient (that I can’t remember how to spell atm). Leaves my teeth feeling good and I notice a whiter shade after I brush than my old toothpaste. I have a strong aversion to weird tasting toothpaste. I like that Ollie doesn’t overwhelm my sense of taste, and what I do taste is pretty good. I’m either going to buy my own toothpaste dispenser (for my gym locker) or buy another tube from Ollie because this is an amazing product
