Abstract: A method to clean the interproximal mesial and distal surfaces of a pair of adjacent teeth, as well as to clean the outer surfaces of the teeth.

Abstract: A method to whiten contacting interproximal mesial and distal surfaces of a pair of adjacent teeth includes the steps of providing a carrier shaped and dimensioned to be inserted between the pair of adjacent teeth, to fit between and separate the interproximal mesial and distal surfaces, and to contact each of the interproximal mesial and distal surfaces; charging the carrier with a tooth whitening composition; inserting the carrier intermediate the pair of adjacent teeth; and, manipulating the carrier to separate the contacting interproximal mesial and distal surfaces and to deliver the tooth whitening composition to the interproximal mesial and distal surfaces by contacting simultaneously the interproximal mesial and distal surfaces with said carrier to contact each of the interproximal mesial and distal surfaces with a portion of the tooth whitening composition on the carrier.
