ABSTRACT:
The present invention relates to a toothbrush having a handle portion including a first end and a second end. The toothbrush further includes a hollow forward portion, an aperture formed through the hollow forward portion, and a spring element having a first end and a second end. The first end of the spring element is secured to the hollow forward portion, and the second end of the spring element is positioned adjacent the aperture of the hollow forward portion. A bristled element is positioned within the aperture of the hollow forward portion, with the bristled element being connected to the second end of the spring element. An actuation element is included within the forward portion of the toothbrush. The actuation element has a first end and a second end, and a finger engaging surface positioned at the first end of the actuation element. The second end of the actuation element is adapted to ride along the spring element, with movement of the finger engaging element serving to move the second end of the actuation element along the length of the spring. The movement of the second end of the actuation element along the spring serves to bias the bristled element out through the aperture of the hollow forward portion. A forward portion cover is dimensioned to fit over the forward portion. A slot is formed within the forward portion cover. The slot is dimensioned and positioned to allow the finger engaging element to extend through it.
