Gone are the days of visiting a dentist and spending hundreds of dollars to whiten your teeth. With modern inventions like teeth-whitening pens, achieving pearly whites at home has never been easier, quicker, and more affordable. If you’re looking for a new pen, the sheer number of products in the market might overwhelm you. Here are the best teeth whitening pens to help narrow down your options.

1. AsaVea Teeth Whitening Pen

If you’ve been looking for a technique to get rid of years of stains caused by coffee, tea, wine, smoking, soda, or any other drink or food, this pen might just be the right solution. It contains 35% Carbamide Peroxide, a common bleaching agent that is strong enough to remove lingering stains but gentle enough to safely use at home daily. In fact, using it regularly can make your teeth up to eight shades brighter.

This also means lower irritation and tingling sensation compared to other whitening pens.
