Crest Whitestrips Pro Effects,10-Day Dental Whitening Formula System, 40 Strips (Packaging May Vary)

I am a dentist who recommends Crest-brand White Strips to my patients becasue they do work to whiten teeth. However, they have to be used correctly and I recommend that you follow the directions exactly as specified inside the box.

1. First brush your teeth with a wet toothbrush to remove the layer of plaque (toothpaste is unnecessary). Rinse your teeth well with water. Tooth enamel has pores, and the pores need to be open for the chemical to penetrate.

2. Use the strips as directed on the box. The instructions will tell you to bleach twice a day for 30-minutes a time. The inner part of the strip has a chemical called hydrogen peroxide; (in-office, or dentist-assisted dental whitening uses a 15-35% version of the same chemical) that causes the stains inside your teeth to be oxidized and turn white. Applying the strips has a small learning curve as you will probably bend or fold a couple of them before you get the technique down.

I was really surprised as I entered my neighborhood bar when my buddy called out, "dude, did you whiten your teeth?! they're freaking glowing!" that pretty much sums up how effective the strips are - and I was only on day 3!

To be objective, my teeth hurt a little when I first put them on, the type of slight pain you feel when you have cavities. I guess this is what they mean by your teeth becoming sensitive. But the pain isn't bad, and it went away after a few minutes. And also, I didn't notice a HUGE difference myself, but there definitely was a change for the better. And I guess to an outside observer, the change was noticeable.

In short, I think this stuff is awesome. I'll definitely finish it, and probably do it again at the recommended time.

Crest Whitestrips is an incredible product. It is virtually the same hydrogen peroxide bleaching solution that dentists use. It's amazing how much whiter they make your teeth after only a few days. I've been using them for a couple of years and decided to try the new "Whitestrips Premium PLUS." This product is exactly the same as the regular Crest Whitestrips Premium- 7- Day Dental Whitening Formula System, 28 Strips, except the box it comes in has a window and it comes with 3 extra days of strips. The regular Whitestrips takes 7 days and this takes 10. After 7 days, your teeth are pretty much as white as they're going to get, and I didn't notice much of a difference from the additional 3 days. The "Plus" in the product's name seems to refer more to the much higher cost of this product.

If you're thinking about getting this, just realize that all it is is three more strips, so when you figure out how much you're being charged per strip, you may find you're paying...Read more
