Device for extending the effectiveness and life of electric toothbrush heads

摘要

A dental oral hygiene device for extending the useful lifetime of replaceable electric or battery operated toothbrush heads having a stem attached to a handle on one end and to a rotating disk at the other end, whose center of rotation is perpendicular to the stem, with a plurality of bristles attached to it. The bristles having a defined length are attached to the disk surface in a round array perpendicular to the stem. Each of the bristles having a proximal end attached to the disk surface and a distal end forming a tip. The device forces the bristles into proper alignment by applying pressure to the bristles along the bristle length, approximately from the bristle tip to a point between the bristle tip and the proximal end of the bristle. The bristles are forced generally inwardly by the device such that the round array is generally maintained and the bristles are prevented from splaying outwardly.
