Teeth Whitening: Listerine vs. Crest 3D?
How effective are the Crest 3D Whitening Strips and Whitening Toothpaste compared to Listerine's? I tried Listerine's mouthwash and whitening strips, and overall, they did a fairly poor job.

I'm actually using the listerine mouthwash and whitening strips with aquafresh whitening toothpaste and my teeth look alot better! I've heard the crest 3D whitestrips are supposed to work better though. :)
