1. A kit comprising:
a) a delivery carrier,
b) a multi-phase oral composition for whitening teeth, comprising:
i. from about 0.002% to about 30% by weight of the multi-phase oral composition of an aqueous phase having a bleaching agent, wherein a concentration of the bleaching agent is up to 10%, by weight of the multi-phase oral composition;
ii. a hydrophobic phase having a cone penetration consistency value of from about 50 to about 500, as measured by ASTM D937-07,
wherein the multi-phase oral composition is a water-in oil emulsion, and
wherein the hydrophobic phase is a predominant portion of the multi-phase oral composition; and
c) an electromagnetic radiation source capable of directing electromagnetic radiation with one or more wavelength in the range from about 200 nm to about 1700 nm toward at least one tooth.
