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.

[ What is claimed is:] [1.] A method for whitening teeth comprising:(i) providing an oral composition which includes a first and second composition each of which is stored separate from one another prior to time of use, the first composition containing from 0.01 to 20% of a peroxide by weight of the oral composition, and the second composition containing from 0.05 to 60% of a bicarbonate salt by weight of the oral composition, and the oral composition having a pH from 9.0 to 12;(ii) dispensing the first and second compositions onto a toothbrush;(iii) applying the first and second compositions from the toothbrush to the teeth:(iv) brushing the teeth thereby mixing first and second compositions together; and(v) repeating steps (ii) through (iv) on a plurality of days, the teeth to be whitened being exposed to the oral composition for the equivalent of 10 seconds to 5 minutes per day exposure until the delta L values of the equivalent use time of combined peroxide and bicarbonate compositions provide substantially greater whitening effect than additive results of tooth whitening with either peroxide or bicarbonate compositions used separately, as represented by differences between colorimeter readings of tooth base line versus values after exposure.
