Patent number: 5902568Abstract: A method for whitening teeth is provided which involves applying to the teeth a mixture of a peroxide and a bicarbonate salt. Advantageously, the peroxide and bicarbonate salt are stored as active ingredients in separate respective compositions of a dispensing container. Preferably the dispensing container is a pump in the form of an upper and lower body telescopically engageable one with another, the upper body including at least two hollow and separate parallel cylinders each containing one of the compositions. These compositions may then be dispensed through relative compression of the pistons within the cylinders.Type: GrantFiled: November 26, 1997Date of Patent: May 11, 1999Assignee: Chesebrough-Pond's USA Co., Division of Conopco, Inc.Inventors: Christine Watson Ryles, Stephen Roy Barrow, David Robert Williams
