The Secret to My Bright, White Smile? These Teeth Whitening Pens

Nordstrom rating: 4.8/5 stars

A Nordstrom reviewer says: “Unfortunately, I was trying to use my rewards to grab this to check it out, and sadly my rewards are broken so, I ordered at full price, but this thing is awesome. It literally does what it says. And that’s why I wanted it. My teeth look so beautiful every day, and my lips enjoy a coat of this whenever I brush my teeth or even if I’m just constantly flossing that day (out and about). Get 2! One for your bathroom, one for your bag!!”

• No sensitivity issues

• Small portions

In addition to the stain-removing pen, this option comes with a sealant that will protect teeth for up to two hours. That means you can enjoy as many espressos as you’d like without worrying about stains.

Amazon rating: 3.6/5 stars

An Amazon reviewer says: “My teeth had worn down so much that they looked transparent in the front. I thought I would need expensive dental work. I saw a dentist on You Tube that was not affiliated with Boka, but he said that Boka has the best dental products on the market right now. I use Boka toothpaste, dental floss and whitening products and to my surprise, my teeth became remineralized and they look younger and thicker. I'm so happy and I recommend Boka!!!”

Amazon rating: 3.9/5 stars

An Amazon reviewer says: “I’ve tried other whitening pens and was impressed with the results. The peroxide based formula gives a satisfying foam effect during use, and I noticed visible results within the first few days. The flavor is not just typical mint, with I think Thyme listed as an ingredient- subtly refreshing. Most importantly, it didn’t leave a thick residue on my teeth like other products I’ve tried. Would recommend to others, just wish price point was lower.”

There’s no messy trays or strips, which makes it super easy. The gel dries fast and stays in place, so you don’t have to worry about it rubbing off.After using it for a while, teeth start looking brighter.
