Smile Direct Club Bright On Premium Teeth Whitening Kit ($40)

No big, bulky LED lights here. The Smile Direct Club Bright On Premium Teeth Whitening Kit is super simple to use, and the treatments will last you up to six months. Just brush the formula onto your teeth and use the LED light to boost its whitening power. It's a weekly treatment that only needs five minutes of your time.

It comes with four gel pens that contain professional strength hydrogen peroxide and an enamel-safe LED light. The LED light powers up when it's plugged into a USB-C compatible outlet or even phone; it even comes with a lightning cable adapter that works with your iPhone.
