Crest Whitestrips Supreme Professional Strength of 84 Strips Full KIT

I am a dentist who recommends Crest White Strips to my patients because 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 to remove the layer of plaque. Do not use toothpaste - just a wet toothbrush. Your teeth have pores and the pores need to be open for the chemical to penetrate.

2. Use the strips once or twice per day according the instructions. With the "Supreme" Crest Whitestrips, once per day is enough; with the "Professional" and the "Premium", use the product twice per day. The inner part of the strip has a the hydrogen peroxide 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.

2. Leave the strips on for 30 minutes at a time. After thirty minutes your...Read more

Here's the scoop on the stuff. It really, really works and it works fast.

As others have mentioned, it does cause sensitivity, big time. But I found out that if I do it every other day, it is no problem. Everyday and twice a day like the instructions tell you will make you a miserable wretch. Also, if you have the strips on upside down, your gullet and gut will let you know how displeased they are.

First, how it worked on me. After the first day, which I did in two consecutive 30-minute treatments (you can do it that way or else wait a few hours in between treatments), I already noticed the difference. My bottom teeth were, for some reason, yellower than the top--plus the area around my gums were yellower than anything (I am a coffee drinker; I have no diseases or cavities and I don't smoke). When I finished both 30-minute treatments, my top and bottom teeth were the same shade, and my bottom teeth were not bi-colored anymore. When I woke up the next day,...Read more

I had the opportunity to try out Crest Whitestrips Professional Supreme after making a visit to my dentist and getting a few sample strips for free. I have been a long time user of the Classic Whitestrips so I was pretty excited to try out the newer advanced kind.

PROS:

- This is some strong stuff-- no joke! It works very well and very fast. I had a few compliments from people about my white teeth after only using the strips twice.

- The strips covered my teeth well, and they even stayed on better than the classic and premium strips.

- I noticed less gel on the strips. It was nice not to have excess gel to spit out while whitening.


CONS:

- MY TEETH HURT SO MUCH the next day. I don't normally have teeth sensitivity like this, but it was VERY PAINFUL. When I went outside and the cold, brisk air hit my teeth, it was like no pain I have ever experienced before. I can handle pain pretty well, but...Read more
