The monograph has an Indication written for it, and using that idea without the monograph is the failure.

How it happens

A fluoride-free tooth powder or an oil pulling blend performs well, customers report fewer problems, and the marketing starts saying it prevents cavities or protects enamel against decay. That is the monograph Indication.

What it creates

An unapproved drug claim on a product with no monograph active at a monograph concentration. The anticaries Indication is available to products containing a listed active at a listed level, and to no others.

Whitening is a separate question

A product sold on appearance is making a cosmetic claim. A product claiming to treat a condition of the teeth or gums is making a drug claim, and peroxide products in particular sit close to that line.

The honest claims are plenty

Cleans, polishes, freshens, removes surface stains, leaves teeth feeling smooth. All specific, all verifiable, and none of them a statement about preventing disease.

And "fluoride-free" is a composition claim

Which is lawful and increasingly a selling point. Saying what is not in the product is a different act from claiming what the product does to caries.

Check everything published

Listings, the website, social posts, influencer briefs and customer reviews you reproduce. The label is reviewed and the rest is not, which is where these claims actually live. The same finding appears in five other properties here under five other statutes.

And the consequence is the whole monograph

A drug claim brings the permitted actives, the identity statement, the Indication wording, the verbatim warning and the Drug Facts panel all at once. One sentence reopens the entire label.

The monograph wrote the sentence people reach for

"Aids in the prevention of dental cavities" exists in the regulation because it is what these products want to say. Using the idea without the monograph active at the monograph concentration is the specific failure, and it is a short step from an honest enthusiasm.
