Crest 3D White with Whitelock technology contains 100 million micropolishers that remove 90% of surface stains and help whiten and polish your teeth to a tee. What makes this toothpaste even more effective and practical is its Whitelock technology which helps lock in your newly acquired brilliant white smile. Smoke, coffee, berries, and every type of food that you might consume and stain your teeth will have reduced effects, as the Whitelock technology covers your now-whiter teeth with a layer that blocks new stains from forming. Use our new Crest 3D White with Whitelock technology twice a day and dazzle your entourage with your blinding white smile.
