These professional-grade whitening strips use the same whitening ingredients as dentists and are also enamel-safe and effective. Its hydrogen peroxide ingredient is both good for your teeth and gums and also powerful at making your teeth a few shades whiter.

How to use? Simply peel, apply, smile and repeat! The bundle includes 20 Professional Effects treatments and two 1-Hour Express treatments, making your beauty routine customizable and based on preference.

It’s recommended to use the standard 20 Professional Effects treatments for 45 minutes. Even better, their no-slip grip means the strips stay put until you take them off. So, you can talk and even drink water while whitening your teeth. What’s better than that?

As a whole, we can’t recommend the Crest 3D Whitestrips enough. While they’re on their *best price ever*, you may want to pick up more than one pack.
