Crest Whitening Strips

Ever since I was little I've had these tiny calcium deposits on my teeth and they're not bad, they just don't look awesome. A couple of years ago my dentist recommended I use the Crest Whitening strips to get rid of them and this was when the whitening strip idea was brand new. These whitening strips are so weird. You're supposed to put on a top strip and a bottom strip for half an hour twice a day (but using them twice a day made my teeth too sensitive, so I only use them once a day or every other day). The strips are these thin pieces of plastic coated on one side with this strange gel-like substance. When they go on, they wrap around the bottom of your teeth and go onto the back side to keep the strip in place. The first couple of times I was really taken aback because I didn't realize the gel squeezes out easily, making for quite a disgusting taste in your mouth. The strips also have a hard time staying in place; they either slide from side to side or up and down. When you're wearing them you talk with a funny lisp and can't really ennunciate your words. I started using them again a couple of weeks ago because the calcium deposits came back and I like having white teeth, but I've definitely come to the conclusion that I hate them. They taste bad, they feel weird, and they make my teeth hurt. The only and certainly major redeeming factor is that they work. My teeth really are whiter and I guess the sensitivity, bad taste, and strangeness of it all is a worthy price to pay for white teeth. My teeth better stay white for 12 months like Crest guarantees or else . . .
