Abstract: An oral hygiene device for mounting on and manipulated by a user's finger comprises a stem, an oral hygiene working head and a clamp for mounting the device on a user's finger. The working head is provided at one end of the stem and the mounting clamp provided at the other end of the stem. The stem includes a stepped portion between the working head and the mounting clamp to elevate thereby a portion of the stem provided with the working relative to the clamps so as to provide a working head essentially as an extension of the finger. The clamp may be formed of plastic having two pairs of opposing lugs. The plastic may be sufficiently resilient to conform to the shape of the user's finger to ensure an adequate secure mounting of the finger. The oral hygiene device of this construction provides a new mode for the delivery of improved oral hygiene to facilitate a quick and accurate arrival at predetermined destinations of the gum tooth junction.
