These crest whitening strips were amazing they're like professional grade but they leave my teeth very sensitive and I can't drink ice cream or smoothies or anything after I use them

The only whitening strips that have actually made a difference. I use it once a week however if you're teeth are sensitive you should do it less often because it will cause shocks of sensitive in your teeth.

It did make my teeth a little more sensitive but not a lot. I noticed a difference in my teeth being whiter however it wasn't that great and some people's

I love using this! It's easy to apply so you don't have to make a mess using those gels. And you don't have to have a bright light shining in your mouth either.

Very effective with coffee and food stains on teeth, I believe a white smile does indeed brighten the whole face. Easy to use, I have used them on my commutes while driving.

I've used these strips my whole life and never disappoint! I always get compliments on how white my teeth are and I've recommended these strips to all my friends and they have said that their teeth have been turned white

Okay. This stuff is the real deal. If you want whiter teeth .. use this. It significantly whitens your teeth, however there is some sensitivity, specially when eating/drinking cold things!

Kind of costly but worth it! It gets the job done ! I would not use this daily because it will cause a lot of pain over time with your teeth so be aware of that. Use every now and then! This stuff makes my teeth so white and I'm never going back!

This product instantly gives you results. I will forever and always use this product to keep my teeth white and pearly. This product not only met my expectations but exceeded my expectations. Will buy again

Comfortable & effective. I use one daily for a week and then once/twice a week after and cycle through that a few times a year. I don't have discomfort with them unless I fall asleep with them on and wear them all night.
