The Product: Crest 3D White Advanced Vivid Enamel Renewal Toothpaste

The Price: $4

The Promise: "Whiten by removing up to 90 percent of surface stains in 14 days with Crest 3D White Advanced Vivid Enamel Renewal Toothpaste. It not only gently polishes away stains, it also strengthens your enamel below the surface for a healthy, lustrous smile."

The Real Deal: I'm realistic when it comes to managing my expectations from a whitening toothpaste. I know full well that in order to get movie star wattage you need to have your teeth professionally whitened. That's why I was wowed by the results I got from using this toothpaste.

While my teeth aren't suddenly dazzling, they have definitely gotten brighter since I started brushing with this paste. And, it could just be wishful thinking, but I'm pretty sure that some of the stubborn caffeine stains I've had for years have started to disappear.

The Upshot: I'll definitely continue to use Crest 3D -- why not? It's affordable, it's safe for the enamel on my teeth, it's effective, and it gives me minty-fresh breath. What's not to like?
