Has anybody ever made it through a box of teeth whitening stripes in a timely fashion? I've been slowly working my way through my box of Crest Whitestripes for about three years. I can't tell if I'm making any progress. The feeling as if I'm having a mouth full of cavities filled with Cadbury Egg cream by a deranged dentist usually warrants that I stop using them. But when certain situations heighten my self consciousness, I resolve that pain is beauty, to grin and bear it. My in-laws visiting this coming weekend is what's prompting my current regimen. Because certainly they give a shit about my teeth? They are going to arrive, drop their bags, grab my chin and demand a smile.
