Go Smile Sonic Blue Teeth Whitening System

Go Smile Sonic Blue Teeth Whitening System, $129, qvc.com

For the past few months, my morning drink of choice has been the Thunderbolt, an iced lemonade-and-espresso combo that is much more delicious than it sounds. The only downside? It seems to be making my pearly whites a bit less pearly. Go Smile has come to the rescue with Sonic Blue Teeth Whitening System, a vibrating toothbrush that has a little LED blue light snug in the center. When you brush, the light activates the hydrogen peroxide solution in the brand’s whitening gel. After a week, I could actually see a difference.
