Reviews

I drink coffee every day and thought my stains were permanent — until I tried this pen. Within 5 days, my smile looked brighter and cleaner. Super easy to use and no pain at all.

Wasn’t sure it would work on vape stains, but I’m seriously impressed. No sensitivity, just results. My teeth are at least two shades lighter already!

— Jason K.Verified Buyer

I love that it takes just 1 minute — twist, brush, done. No trays, no mess. Just whiter teeth and real compliments from people around me.

— Rachel S.Verified Buyer

Honestly, I keep one pen in my purse at all times now. I’ve tried whitening strips before, but this is way faster and less annoying.
