Powered Radiofrequency Toothbrush
Dental
The Powered Radiofrequency Toothbrush is a dental device consisting of a handle containing a radiofrequency generator that delivers radiofrequency energy to a brush applied to the teeth, intended to remove adherent plaque and food debris to reduce tooth decay. It is a powered oral hygiene device distinguished from conventional electric toothbrushes by its use of radiofrequency energy. This device is classified as FDA Class 2, requiring 510(k) clearance, under regulation 872.6866 in the Dental specialty. It carries product code QMJ and is not an implant and not life-sustaining.

A predicate device is a legally marketed device that a new 510(k) applicant uses to demonstrate substantial equivalence. The FDA's 510(k) pathway requires manufacturers to show that their device has the same intended use and similar technological characteristics as one or more predicate devices already cleared for commercial distribution.
Finding the right predicate is a critical step in 510(k) strategy. Manufacturers typically search for cleared devices with the same FDA product code, which groups devices by their intended use and regulatory classification. This tool helps you identify potential predicates by browsing all clearances within a product code.
Note that predicate devices must be legally marketed — they cannot be devices that were cleared but never commercialized, or devices subject to a mandatory recall. The determination of substantial equivalence considers intended use, technological characteristics, and performance data.
