Don’t have time for an intensive at-home whitening treatment? Brian Kantor, DDS, a New York-based cosmetic dentist at Lowenberg, Lituchy & Kantor, who treats stars like Penelope Cruz and 50 Cent, suggests this toothpaste for brightening on the quick. “This toothpaste will make teeth appear brighter instantly. It contains Bluverite® technology, which deposits blue microparticles onto teeth and creates the optical illusion of whiter teeth. As with all other whitening toothpastes, it removes surface stains on the teeth and makes teeth appear whiter than they originally were,” he says.
