For many years I had perfectly white teeth. They were so white that they were whiter than the lightest color on the little paper the dental hygienists used to determine teeth discoloration. The reason for my supernaturally white teeth had nothing to do with my genes or flossing habits, but because for 20 years I never drank pop, tea, coffee or red wine and never smoked, the products that have been shown to discolor teeth. In essence, my teeth were pearly white virgins.
But all that changed last year when I discovered just how much easier my life was with the addition of caffeine, when Earl Grey became my drug of choice. 9 AM classes were suddenly tolerable, while writing for 3 straight hours was almost a breeze with a never-ending cup of tea by my side. I'll start drinking tea when I wake up and just keep refilling the cup until lunch, not including the green tea I like to have after dinner. I'd guess I average between 4 and 8 cups of tea a day.
I hadn't thought about any negative side effects of my new habit until I had my annual checkup at the dentist, when the hygienist asked when I started drinking coffee once I'd settled in the chair. "Black tea," I replied. "You should think about whitening, you've got some overall discoloration and a few noticeable stains," she said. Unwilling to shell out a few hundred for professional whitening, I vowed to try the drugstore alternative.
When I came home, I found a box of unopened Crest Whitestrips
hiding in the back of my cabinet. "Score!" I thought, "I've just saved $25." I began using the strips twice daily as directed, and didn't notice any of the gum or teeth discomfort that they'd warned about on the box. After about 3 days I was noticing a decrease in the staining and a general lightening effect, maybe half a shade or so. I should mention that my teeth weren't very stained or dark, they were just a couple shades darker than usual, and with my pale skin, it was becoming more visible.
After 5 days of using the strips, I accidentally knocked over the box and noticed the expiration date on the bottom of the package. For some reason, it never occurred to me to check for an expiration date, but there it was- 03/28/2004. "2004!" I thought, "These strips were probably produced before I started high school!" To assuage my fears that I could have been poisoning myself with peroxide gone bad, I did a Google search and found that expired Whitestrips are safe, just less effective as time goes on. God bless the internet.


I decided that if I wanted the real deal, I should just go out and buy a new box, which I did. Not surprisingly, the new strips were far more effective than the expired ones. One day of using them and I noticed more of a difference than the previous 5 days. Unfortunately, I could also feel them working, as they burned my gums and made them far more sensitive to brushing. Still, the pain was tolerable, and encouraged by the progress I'd made, I stuck with them for another week, taking a break once to let my gums heal. Crest recommends using them for 2 full weeks, but I was able to get rid of all my stains and discoloration after 7 days of use, so I decided to stop there.
Overall, I was very impressed by the results I saw, and I'd recommend the product to anyone who wants whiter teeth but doesn't need the full dentist whitening. After a couple days of not using the strips, my gums are healing and are becoming less sensitive. If you do experience sensitivity, I've read that it helps to stagger treatments (every other day instead of every day, etc) and to use a sensitive toothpaste like Sensodyne. Also, Crest offers a number of different strengths of Whitestrips, including Premium and Premium Plus, which are more expensive than the "Classic" formula and promise to work faster. I haven't tried them, but unless you've found the regular version to be too weak, I'd recommend skipping the pricier formulas.
Anyone else have experience with other whitening products? I've always been curious about the GoSmile kits at Sephora and the numerous whitening toothpastes on the market.
