No
The device description explicitly states it is a manual device with a simple mechanical principle of operation, and there is no mention of AI, ML, or any related concepts in the summary.
No
The device is described as a manual tool for removing plaque and food debris from the tongue, similar to a tongue brush or scraper. Its intended use is solely for hygiene and cosmetic purposes, not for treating or preventing any disease or medical condition, which would categorize it as a therapeutic device.
No
Explanation: The device description states its purpose is to "remove plaque and food debris from the surface of the tongue," which is a cleaning function, not a diagnostic one. There is no mention of it being used to identify or analyze any medical condition.
No
The device description explicitly states it is a manual device composed of plastic, rubber, nylon, or stainless steel, indicating it is a physical hardware device, not software.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- Device Function: The Enfresh Tongue Brush is a manual device used to physically remove plaque and food debris from the surface of the tongue. It does not analyze any biological specimens or provide diagnostic information.
- Intended Use: The intended use is purely mechanical cleaning of the tongue surface.
The description clearly indicates a physical cleaning tool, not a device for analyzing biological samples.

Device Description
The Enfresh Tongue Brush and the predicate tongue brushes, tongue scrapers, and tongue cleaners have very similar principles of operation. They are all manual devices that are used by applying a brushing, scraping, or both brushing and scraping motion to the surface of the tongue to remove plaque and food debris from the surface of the tongue.
The Enfresh Tongue Brush and the predicate devices also have very similar technical characteristics. The handle and the bristles of the Enfresh Tongue Brush and Garry Laboratories's The Tongue Brush are composed of plastic, rubber, and nylon, while Telefax International's OOLI-U (Tongue Scraper) is composed of stainless steel. Both plastic and stainless steel are durable, biocompatible materials that have a long history of safe use in devices.

Intended Use
The Enfresh Tongue Brush and the predicate devices are intended to be used to remove plaque and food debris from the surface of the tongue. These devices are indicated for use several times a day, followed by rinsing the mouth and tongue with water.
Technological Characteristics and Substantial Equivalence
The Enfresh Tongue Brush and the predicate tongue brushes, tongue scrapers, and tongue cleaners have very similar principles of operation. They are all manual devices that are used by applying a brushing, scraping, or both brushing and scraping motion to the surface of the tongue to remove plaque and food debris from the surface of the tongue.
The Enfresh Tongue Brush and the predicate devices also have very similar technical characteristics. The handle and the bristles of the Enfresh Tongue Brush and Garry Laboratories's The Tongue Brush are composed of plastic, rubber, and nylon, while Telefax International's OOLI-U (Tongue Scraper) is composed of stainless steel. Both plastic and stainless steel are durable, biocompatible materials that have a long history of safe use in devices.
Summary Basis for the Finding of Substantial Equivalence
The safety and effectiveness of the Enfresh Tongue Brush is based on the long history of safe use of tongue brushes, tongue scrapers, tongue cleaners, as well as the safe use of manual toothbrushes. The Enfresh Tongue Brush has the same intended use and very similar principles of operation and technological characteristics as the predicate devices. Thus, the Enfresh Tongue Brush is substantially equivalent to the predicate devices, because the Enfresh Tongue Brush raises no new issues of safety or effectiveness.
