A toothbrush includes a handle and a head mounted to the handle. The head may generally include a membrane attached to it and configured for attachment to a cleaning element. The membrane may be generally dome shaped and may be resiliently flexible when a brushing force is applied. A plurality of cleaning elements is mounted to the membrane. The cleaning elements may be attached using anchor free tufting. In addition, the cleaning elements may be sufficiently spaced so as to allow separation of the melted portion of the cleaning elements. In another arrangement, the head may also include walls or dams positioned between the cleaning elements. The walls prevent the melted portion of the cleaning elements from merging with the melted portion of another cleaning element. This isolation of the molten nylon allows the cleaning elements to move independently of each other.

An oral care implement has an improved handle for control. The handle may include a gripping region having a grip surface with a plurality of spaced slot openings exposing portions of the base. In one construction, the handle may have an inclined portion and a grip body extending through a base of the handle. The grip body forms opposite finger grips on the inclined portion of the handle. In one construction, the handle may include a grip element which provides shifting of a mass centroid of the handle during use. In another construction, the handle includes a resilient grip body and the handle includes an aperture extend through the handle. Aperture has an inclined surface for engaging a resilient grip body.
