Started using it before a big event, even though I really didn't Believe it will do any thing. Omg this product changed my life. I got so many complements!. Never felt had that much confident smiling :).

Unfortunately these haven’t worked for me. I ate nothing but white food to make sure I didn’t do anything to hinder the whitening process. They worked great a few years ago, so maybe I got an old box (could not find any expiry date anywhere)

I’ve used these off and on for many years and have always liked them. They do a great job and my dentist even noticed. They don’t harm your teeth or make them real sensitive.

You can NEVER go wrong with using these. However, I find that every time after using a white strip, my teeth become extremely sensitive for a couple hours so I tend to not use these often.

Crest is the only brand of whitening strips I will use. Work great and can really notice a difference even after a few days of using! I drink coffee everyday and these really help get away those stains on my teeth

This is one of my favorite teeth whitening products out !!!! It’s my go to and it don’t make my teeth hurt !!! And i can tell a big difference with one use !

Love, love this product took years of stains off my teeth to leave me with glistening white teeth. Teeth look white, clean, and healthy. Not as pricey as a dental whitening treatment from a dental office. Well worth the money. Highly recommend it.

HATE! They did their job of course BUT I fell asleep with mine on and I was in more pain than I’d been in my entire life! They’re obviously TOO strong.

Its good but i have sensitive teeth and after a few uses my teeth are sensitive. Also any calcium deposits come right up with use so before sometimes can look spotty. Its ok, been on the hunt for a better product

These actually really hurt my teeth but I think that they did help make my teeth whiter. I don’t like how they have to stay on for so long but if they work I will do anything to make my teeth more white
