Abstract

This product is a toothbrush designed to help children learn the correct way to brush their teeth. The toothbrush handle is triangular in shape, making it easy for children with small hands to perform the rolling brushing motion (brushing at an angle to the teeth) while holding the toothbrush in a pencil-like grip. Furthermore, unlike the common "fist grip" where children wrap their index finger to little finger around the toothbrush and cover it with their thumb, the pencil-like grip allows for the rolling brushing motion, enabling them to brush their teeth without applying too much pressure or damaging their gums. The toothbrush handle is triangular in shape, differentiating it from conventional toothbrushes with flat handles, allowing for a secure grip.
