A toothbrush is proposed that includes a handle, a neck, and a head arranged along a longitudinal axis thereof. The head is open on one side and functions as a protective screen. Movable ring-shaped holders with bristles radially secured thereon are mounted in the head. The holders butt ends are joined to one another and to the protective screen by movable seals forming a hermetical body to protect the toothbrushs drive mechanism from penetration of water and toothpaste. Two design options allow the holders for accomplishing-angular oscillatory movements, or -rotating in opposite directions about the longitudinal axis, thus ensuring bristles movements from top to bottom along the users teeth. The proposed design ensures a high cleaning effectiveness, water tightness, and compensation of a reactive torque of the toothbrush, which extends the service life of the toothbrush and facilitates the use thereof.
