#AD #ColgatePartner How do you know that a whitening toothpaste ACTUALLY whitens your teeth? The answer is this ingredient.. Hydrogen Peroxide. Hydrogen Peroxide is able to break down stains in your enamel and dentin to give you a whiter and brighter smile. @Colgate US Optic White Pro Series Toothpaste’s hydrogen peroxide is able to remove 15 years of stains in 2 weeks (when brushing twice a day)!!! #teethwhitening #colgateopticwhiteproseries #dentist
