ABSTRACT:
An oral hygiene device to be secured to a first end section (16). A gingivae massage element (22) is secured to a second end section (18) of the toothbrush (12). The massage element (22) substantially defines a chordal segment of a cylindrical contour which has an arcuate contour outer surface (24) for compressively interfacing with the gingivae of a user. The gingivae massage element (22) includes a planar chordal surface (26) which is secured to the second end section (18) of the toothbrush (12). In this manner, the gingivae massage element (22) is compressively and deformably pressed against the gingivae lining during a massaging motion with a minimization of the possibility of injury to the tissue through any force application.
