Approx Cost $25-Active Ingredient Hydrogen Peroxide.
After 3 days of using the strips two times a day, I did notice my teeth lightening slightly. It’s fairly cost effective and can be found at nearly every drugstore. I cannot stand that slimy feeling of the strips foaming up in your mouth though, and you are inevitably swallowing lots of the foam. (The foam is caused by the hydrogen peroxide.) Also, since you have to wear them twice a day for 30 minutes each time, this means that, unless you plan where you are going to be in 30 minutes, that sometimes you are ripping then off of your teeth and then flinging them from your car window (You know you’ve done it.)
Sometimes I lose track of time and run late, which I’m sure I did when using the Crest strips, because my teeth ached after I used them. A LOT. Easy, worth the money, but set a timer unless you want to feel like your teeth have flu symptoms for a day or even TWO. I couldn’t even touch or look at paper-towels for several months after just three days of Crest White Strips usage. Touching paper towels felt like nails on a chalkboard sounds, if you know what I mean :/
Pros – Teeth were a little whiter after a week- and probably would have been whiter had I been able to remember to use the dang things everyday.
Cons – I left them on overnight once and now can’t use paper towels for a month- so my teeth are SUPER sensitive and I’m always wiping my hands on my shirt.
Last Call – Whiter but painfully SPOTTY
