I love how white my teeth can get with this product. But a few times I've had my teeth become super sensitive really quickly. I've used this product a lot and I only experienced the sensitivity a couple times. I still use these strips.

I've only used strips a couple times and my teeth hurt so badly after. I have been told there are some for sensitive teeth so maybe I'll try that. Results were great teeth just really hurt after

I used these products and did not see much of a difference. I only gave it a try one time, but I feel for the price of these one time should definitely make an impact. I would not recommend.

These work but they HURT. And they're expensive. If you have sensitive teeth beware it hurts while you're whitening, and then for like 48 hours after. It's awful to feel like it hurts inside your teeth. It kept me up at night.

Do not use on sensitive teeth until you strengthen them! This works very well after 30 mins I noticed my teeth were 2-3 shades whiter and the more I use it the whiter they get! I would recommend not using it too often as it breaks down enamel

This really works! It also doesn't damage your teeth and it is super easy to use. Only 30 minutes for 10 days and you'll have pearly whites in no time!

Whenever i'm looking to revamp my smile I turn to Crest whitestrips. They are easy to use, and get the job done without spending copious amounts of money to get them done professionally. I love these strips and will definitely keep up my use!

I found these to taste weird and I really didn't feel like they were working. I looked into them unfortunately after trying them and found that some people complained about increased sensitivity after using.

I love whitening strips but they can get expensive and sometimes leave stains on my teeth. I like how the end result is but it's never as white as I want it to be and definitely doesn't last so you have to keep doing it

these are GREAT! i was already seeing big differences after like one use! my teeth are very sensitive and i can't use them often without my teeth hurting, but i use them occasionally and my teeth don't hurt and they're looking a lot whiter already!
