Colgate-Palmolive Co. introduces the new Colgate Wave toothbrush. By starting the design from the handle instead of the head, Colgate scientists were able to develop a brush that looks and feels radically different. It has a unique, nonslip, molded handle, designed to fit snugly in the patient`s grip. The toothbrush offers more than comfort; an independent clinical study showed that the new Colgate Wave toothbrush helped to remove plaque more effectively than two different flat-trim brushes.
