Abstract:
1. A method of brushing teeth, the method comprising the steps of: providing a handle having a head end and handle end that is sized and configured for grasping by a human hand, wherein the handle is provided with the head end having a trapezoidal cross section; providing a head having a base that is sized and configured to snap onto the head end of the handle, and bristles that project outward from a first side of the base, wherein the head is provided with toothpaste disposed in the channel; aligning the head end with an open top, longitudinally extending channel formed on an opposite, second side of the base, said channel defined and bounded by two opposed flexible inwardly convex walls; and pressing and sliding the head end in a direction parallel to the outward projection of the bristles towards the channel; spreading initially one or both of said flexible inwardly convex walls by the head end of the handle; and snapping the head end into the channel, wherein said flexible inwardly convex walls then move back toward one another and into the operational position; wherein the handle is provided with rounded concave walls bounding opposite sides of the head end to snugly cooperate with said flexible inwardly convex walls to prevent longitudinal movement in a longitudinal direction along the handle after attachment with the head, and the head is provided with the channel having a trapezoidal profile sized and configured to receive the trapezoidal cross-section of the head end of the handle such that the trapezoidal cross-section and profile cooperate to prevent movement of the head in the direction parallel to the outward projection of the bristles, and wherein the pressing and sliding step squeezes at least some of the toothpaste into spaces defined between the bristles.
