A toothbrush that facilitates brushing even by individuals with limited manipulative dexterity includes a handle, a head mechanically coupled to the handle, and an array of bristles secured to the head and extending outwardly therefrom in a plurality of directions, such that, when the head and the array of bristles are viewed in cross-section, the bristles occupy a first sector of a circular area that is greater than sixty (60) degrees, but less than or equal to two hundred forty (240) degrees of the circular area, and wherein the remaining at least one hundred twenty (120) degrees of the circular area is devoid of any bristles. Such attachment of the bristles increases the likelihood that the teeth will be brushed properly irrespective of the orientation of the head in the mouth, while also reducing the likelihood that sensitive areas of the mouth will likewise be brushed. In another embodiment, the toothbrush includes a head, an array of bristles extending outwardly from the head, and a substantially C-shaped handle mechanically coupled to the head. The C-shape of the handle enables the handle to be easily grasped by users, while also facilitating improved maneuverability of the toothbrush, providing over-insertion protection, and being amenable to caregiver assistance.
