In just seconds a day, the whitening serum in the Teeth Whitening Pen does what brushing with a regular toothpaste can't do. Brush it on, and the serum adheres to teeth, allowing the whitening ingredients to penetrate and remove stains inside and out, for a significant improvement in just a week! The first time you use it, you may have to twist the dial many times to prime the pen, but after that, it's fast and easy to use twice a day, anytime, anywhere!
