ADA Seal-Listed Electric Toothbrushes Under $100
The ADA Seal is awarded per product, not per brand, and several makers' listings claim it for models the ADA's own search does not name. So each brush here was checked against the ADA's product search itself. 7 under $100 passed. The AquaSonic Icon is the cheapest of them to own over three years, at about $75. What the Seal does and does not certify is explained on the ADA Seal explainer.
How this list is ordered: Included only when the ADA's own Seal product search had a live listing naming the model or a series or model list that includes it; a maker's own "ADA accepted" badge alone does not qualify. Under $100 at the snapshot price, ordered by three-year cost. 7 of the catalog’s brushes qualify.
