Powered by HP Complex, our unique formulation of Hydrogen Peroxide, Optic White Advanced removes 5 years of deep-set stains for visibly whiter teeth*. This clinically proven formula contains Hydrogen Peroxide, the same whitening ingredient used by dentists. Designed for no tooth sensitivity, our mint toothpaste provides enamel-safe stain removal for noticeable results*. Colgate Optic White Advanced is an anticavity fluoride toothpaste that starts whitening after the first brush. Most other whitening toothpastes** only target surface stains, but Optic White's dual-action formula with HP Complex gently diffuses below the surface of teeth as a deep-set stain remover toothpaste while micropolishers brush the surface clean. Advanced Sparkling White Toothpaste dissolves deep-set stains without weakening enamel. Specially designed for no tooth sensitivity, Advanced Sparkling White helps protect enamel during stain removal. Feel refreshed with this mint toothpaste. Infused with herbal undertones, its cooling blend of peppermint toothpaste and wintergreen toothpaste flavors delivers an invigorating sensation from start to finish. *when brushing twice daily for 2 weeks **without hydrogen peroxide
