Good deal on Crest teeth-whitening strips
by Mark Frauenfelder from on (#4E4MW)
As a person who drinks copious amounts of tea and coffee, I can attest to the efficacy of these teeth-whitening strips. You just attach the tape-like strips to your upper and lower teeth and wear them for an hour (I usually forget I have them on because I'm so engrossed in my work). I noticed a big difference after the first day (the full course runs seven days).
