Expert Reviews


What reviewers liked

I used this three or four nights in a row and saw my teeth go from yellow to a nice, bright white
Since this pen does actually contain a bleaching agent, it will likely produce better results than even the best charcoal whitening products.
Looking for something that'll brighten your smile while you get your beauty sleep? Your best bet is Colgate's Overnight Whitening Pen, which is formulated to remove 15 years of surface stains in as little as a week.
- Byrdie
This pen uses an enamel-safe formulated gel that creates less response from sensitive teeth and gums. The pen uses a controlled amount of gel in order to prevent irritation with your gums.

What reviewers didn't like

Formula may harden on teeth or brush
some customers note that the product dries up quickly and can be challenging to apply
Brush can get clumpy
