PURPOSE: A finger toothbrush using a thumb and an index finger is provided to more effectively and easily brush every part of teeth and to generate massage effects on the teeth. CONSTITUTION: The finger toothbrush includes an index finger insertion hole(101), a thumb insertion hole(103), a connection part(102) between the index finger insertion hole(101) and the thumb insertion hole(103), a tooth brush(104) at the one top end of the index finger insertion hole(101). Instead of using tooth brush, projection or recess is used to create massage effects on the teeth. To ensure that the fingers are tightly held by the finger toothbrush, knots(108) are formed at regular intervals on the finger toothbrush.
