Crest Classic 100% More Pack Whitestrips, 112-Count

The "Crest Classic" whitening strips are a good buy but be weary of the time needed to whiten your teeth. The instructions tell you to not brush before applying the strips so if your teeth are sensitive; you might want to wait at least a half hour before you apply. You might also feel a burning sensation due to the peroxide in the strips. It's recommended that you keep the strips on for at least 30 minutes so during that time, your mouth might produce lots of saliva. Overall, the strips work well but not as well as the "advanced" more pricey strips. If you want your teeth as white as quickly as possible, do not buy this product. It's a simple equation, low peroxide longer wait, higher peroxide level shorter wait but teeth might become sensitive.

We do snowmobile hillclimb races and I noticed in the pictures of me that my teeth were yellow in the pictures. I was recommended this product by a pharmacist. I had to use 2 store packages because my teeth were so bad. Now they are very white and I get comments constantly about how pretty my teeth are! For some reason, I cannot find this product in the store any more and was able to find it on line with more than twice as much for pennies more. I highly recommend Crest Classic Teeth Whitner Strips and ordering it online saves you a lot more money.

My husband I are both ex smokers, so we had slightly discolored teeth. After a week of using these, I could tell a huge difference. Almost all the stains were gone! And after two weeks, our teeth were white again.
The gel inside the strips can be kinda a weird feeling but other than that this is a great product.
