Claim:
1. A method of maintaining and prolonging the effects of teeth bleaching selected from a group consisting of mechanically abrading stains on an enamel layer of teeth and penetrating through the enamel layer to whiten stain deposits in dentin of the teeth, the method comprising: forming a protective seal that lasts for a period of time of at least about 10 minutes to as long as about 24 hours over teeth bleached by said teeth bleaching within three days of said teeth bleaching, the protective seal formed by applying a temporary stain repellent to the teeth before applying a pigment deposit to the teeth; and applying the pigment deposit to the teeth during the period, wherein the protective seal prevents the pigment deposit from directly accessing the teeth, thereby substantially preventing staining of the teeth during the period, wherein the protective seal wears off during the period.
