FDA posted a page on clear dental aligners September 9 saying it has not authorized any clear aligner sold directly to consumers without a prescription. The aligners it has cleared are prescription devices under product code NXC, intended for use under the supervision of a licensed dental professional.

The agency recommends an in-person examination, which it says lowers the risk of uneven bite, unintended tooth movement, pain and tooth loss. Virtual visits can supplement care but should not replace periodic in-person evaluation. FDA lists adverse event reports of new or worsening dental pain, jaw pain, bite problems and misalignment tied to unauthorized direct-to-consumer products.

No classification changed and no new requirement arrived with the page. What arrived is the agency's position written down in one place, in the language it would use in a letter. Anyone building an aligner business where the prescriber is nominal should read it that way.
