A method of forming a head plate for enhanced cleaning action during brushing. In one embodiment, the invention can be a method of forming a head plate comprising: a) forming a mounting plate comprising a first section and a second section, the first section separated from the second section by a gap, a groove formed into the second section that extends from the gap to a cleaning element location; b) positioning the mounting plate in a mold cavity; c) injecting a molten resilient material into the mold cavity so that the molten resilient material: (1) flows into the gap; (2) flows into the groove; and (3) flows into a cleaning element chamber; and d) solidifying the molten resilient material, the solidified resilient material in the gap coupling the first and second sections of the plate together, the solidified resilient material in the cleaning element chamber forming a first resilient tooth cleaning element.
