Abstract
A toothbrush is provided having an elongated handle and a brush head supported by the handle. The brush head has a base and a plurality of bristles that are arranged in sections. Each section has bristles that extend from the base to form a contact surface elevated from the base. One or more of the sections include bristles that extend to varying lengths from the base to form a contact surface that inclines or declines relative to the base. The sections of bristles further include a first outside section having a contact surface that declines inwardly, an inside section, adjacent the first outside section, having a contact surface that declines outwardly toward the first outside section, and a second outside section positioned adjacent an opposite side of the inside section from the first outside section. The second outside section has a contact surface that declines inwardly toward the inside section.
