Let’s all assume you already upgraded your toothbrush, so what’s the next step to whiter teeth? Well, judging by the thousands of Whitestrips have readers have purchased over the years, I might start there. These are the Professional Effects strips which means they’re a little stronger than the typical whitening strips, claiming to remove 14 years of stains (for comparison, the Glamorous White strips claim to remove 10 years).

This 20-pack box is listed for $30, which is way down from the usual $44, and on top of that, you get two 1-hour express whitening strips to ramp up the whitening process.
