Crest Pro Health HD isn’t just toothpaste - it’s a two-step system for whitening your teeth. First, brush your teeth for one minute with the toothpaste from the Step 1 tube, then without rinsing, brush for another minute with the perfecting gel from the Step 2 tube to whiten.

Crest claims it’s the biggest breakthrough in toothpaste since flouride, and hopefully this one won’t be used as a government mind control drug.
