Safety fingertip toothbrush

InactiveUS6874194B1Stable instrument for oral hygieneConductive stabilityBoard cleaning devicesCarpet cleanersEngineeringThumb
The invention is a safety fingertip toothbrush for use by persons not desiring a full length toothbrush for space conservation reasons, but still desiring their regular oral hygiene practice using a toothbrush. The safety fingertip toothbrush is also a practical solution to safety hazards presented in penal institutions, where conventional toothbrushes with hard handles can pose a risk of being converted to lethal assault weapons. The safety fingertip toothbrush has no handle, but it includes a plurality of bristles embedded in a brush head, the brush head having a depression in one end to accept the fingertip of a finger and an elastic band connected to a thumb ring within which the thumb is placed, allowing for the user to brush their teeth and other mouth tissue using the fingers as the brush handle.
