They work great! After only one use my teeth are noticeably whiter. It does however hurt my husbands teeth, so if you have sensitive teeth it might not be for you.

My teeth want white instantly after 2 weeks. I was not expecting any of this results at al buh it really surprised me. I had a bit of trouble putting it on but I got the hang of it and I would recommend and buy it again!

Great knows how to whiten teeth. After I go through a box, I always get compliments on how my teeth look. The only improvement would be to find a way to not irritate the teeth so much while keeping the whitening product strong.

This is an ok product. Doesn’t whiten ur teeth like the commercial says but it does whiten them some. I would like to see a kit that truly whitens your teeth. I would recommend this product but not without some trepidation

I like these Whitestrips from Crest! It does what it promises and I don’t think my teeth get overly sensitive afterwards. I wouldn’t use it for consecutive days though. I would definitely buy it again.

Effective whitening strips. Results can be seen in 2 weeks if you follow the instructions given. However, it leaves teeth sensitive the next day after use. Recommended to use alternate days instead. Will repurchase!

The work! After the first use. I leave mine on anywhere from 30 min to 60min. I will say they can irritate your gums. So watch for that. The price is reflective of quantity and quality. I usually buy one box a year for maintenance.

This is my favored teeth product by far. These whitening strips are so amazing and work wonders no matter how bad your teeth are. They don’t irritate you teeth leaving them sensitive either. They give you the brightest smile.

All I can say is wow!! The first day I noticed a change! It’s like having it done at your dentist without the big price tag! I use it about four times a week the first week. I achieved my desired shade and now it’s once a week and I drink coffee!

These are super easy and effective. Just remember to not drink anything for the next hour or so for best results. This is a great way to get results without breaking the bank.
