Devices and methods for applying oral care with an adaptable mouthpiece assembly. The adaptable mouthpiece assembly includes a support plate configured to be inserted in a mouth of a user, and a chain member configured to accommodate a section of teeth and gum of the user. The chain member includes a plurality of shackles that are arranged successively on the support plate and that are hingeably coupled to each other. A posterior shackle is coupled to the support plate via a first fixed pivot. An anterior shackle is coupled to the support plate via a movable pivot. A configuration of the plurality of shackles is adjustable by allowing the plurality of shackles to move freely in a horizontal plane along the support plate between the first fixed pivot and the movable pivot.

A toothbrush including a main member that includes a handle portion, a neck portion and a head portion. At least one brush member, which forms at least part of the brush head along with the head portion and is movable relative to the head portion, is disposed in the head portion. The at least one brush member can be moved under the effect of a cleaning movement manually exerted on the teeth.

An improved toothbrush is provided. The improved toothbrush includes first and second flexible anchor portions; a plurality of bristles coupled to each of the first and second flexible anchor portions; and a soft pivot bar operably coupled to the flexible anchor portions. A chewing force applied to the pivot bar causes the pivot bar and the first and second flexible anchor portions to compress against a tooth surface to cause a cleaning action.
