Published abrasivity numbers are replacing whitening claims
Relative dentin abrasivity measured under ISO 11609 has become the deciding specification for retail listings in Western markets, because a buyer facing a dental complaint needs a number rather than a marketing claim. Only 31% of products currently disclose one. The participants who test and publish are recovering listings that the category lost between 2021 and 2024, and they are doing it without changing anything a consumer can see. The testing costs little and takes weeks, which makes the general reluctance to do it commercially difficult to explain at all.
