  • Patent number: 11938206
    Abstract: A kit includes a multi-phase oral composition for whitening teeth and an electromagnetic radiation source. The multi-phase oral composition for whitening teeth includes from about 0.002% to about 30%, by weight of the multi-phase oral composition, of a discontinuous aqueous phase having a bleaching agent, where a concentration of the bleaching agent is up to 10%, by weight of the multi-phase oral composition, and at least about 50%, by weight of the multi-phase oral composition, of a continuous hydrophobic phase of petrolatum. The electromagnetic radiation source is 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. The electromagnetic radiation source emits electromagnetic radiation in a range from about 100 mW/cm2 to about 250 mW/cm2.
