Abstract: A toothbrush that includes a handle having a grip constraining portion which prevents users from gripping the toothbrush along a grip constraining region when they are brushing their teeth. The toothbrush is configured to induce the user to hold the toothbrush on a gripping portion in a specific grip. An angled extending length is positioned adjacent to the gripping portion and extends to the head of the toothbrush. When the user holds the toothbrush at the gripping portion, the angled extending length is configured so that the bristles on the brush head extend onto the user's gums at a desired angle, such as a 45° angle.
