Abstract
An oral care implement having a head with bristle tufts. The head may have a front surface with a central portion that is convex along a longitudinal axis and a transverse axis of the head. Tuft holes may be located within the central portion of the head with each of the tuft holes having a first depth. A rear surface of the head may be planar. A plurality of bristle tufts may be coupled to the head with each of the bristle tufts located within one of the tuft holes. The bristle tufts may have tuft axes that are parallel. The bristle tufts may have distal surfaces that form a convex profile along the longitudinal and transverse axes.
