Yesterday I started using Crest WhiteStrips. I went to the dentist last week, and had a very thorough cleaning, so I thought it was the perfect time to whiten my actual teeth instead of all the fuzzy tartar and plaque that has been building up as I postponed and postponed and postponed again.
The strips are easy enough to use, as far as applying them, however it's kind of annoying keeping them on for 30 minutes. I'm the kind of person who can't leave things alone. If I get popcorn stuck in my teeth at the movies, I will rub my tongue raw trying to get it out instead of leaving it alone until I get home and removing it properly with floss. So, half an hour of these things in my mouth is almost maddening.
Plus, you aren't supposed to swallow the bleach (duh) but when it mixes with your saliva, it kinda bubbles up over the strips, so you have no choice. And it tastes bad. And the strips, with the bubbling of the bleach, feel like they are pulling away from you teeth, so you have to keep running your tongue or finger along them to re-stick them. Then I'm paranoid that I will get the bleach on my clothes, or whatever.
But besides all this, I think they work well. I notice a difference, although I wish they had come with a little whitening guide so you can find what color your teeth are when you start the process, and what color they end up. SB suggested taking digital photos, but I think it wouldn't be as accurate because you'll never have the same lighting. I'll try to remember to post a shot when I'm done my 14 days of treatment.
