The one with the receipts

Hydroxyapatite toothpaste is not a wellness trend that arrived in 2019. It has been sold as an anticaries agent in Japan since 1978, and Apagard is the product most associated with that history. On evidence quality it takes the only perfect score we award.

It ranks fourth anyway, because our rubric weights formula purity and daily experience, and this is where a product designed for a different market and a different era shows its age. The ingredient list includes surfactants and additives that the cleaner American brands have engineered out.

The flavor problem

Be prepared for this. Japanese toothpaste runs sweeter and softer than the sharp cooling mint Americans expect, and Premio is no exception. It is not unpleasant, but it is unfamiliar in a way that a meaningful number of people never get past.
