Electric toothbrush

Abstract

An electric toothbrush has a first brush that oscillates and a second brush that oscillates opposite the first brush. The electric toothbrush also has a shaft assembly that includes a moveable pin that creates an oscillating motion of a first brush on a head of the toothbrush. The method of assembly inserts a shaft assembly of the toothbrush through a bottom hole of an elongated hollow body of the toothbrush head to come in contact with a top hole of the elongated body.
