I use these occasionally when I'm looking to brighten my smile and they work SO WELL!! If I go through the whole process for about a week, my teeth become so white. To upkeep that, I just use a strip every so often.

Whenever I actually have the discipline to use regularly, my teeth are noticeably whiter. The strips stick to your teeth without slipping like other products.

I don't know what took me so long to try these. I'm 50 and take good care of my teeth but they were definitely yellow. I was skeptical but they do indeed work and I saw results.

Are used to wear these the night before I cheered games in college because I never knew when I was going to be on camera and I always wanted a perfect white smile

These white strips work as well as getting trays from the dentist! Plus they are much cheaper. My teeth always look lighter even after one use. The only drawback is that my teeth are more sensitive for a day or so.

This product works super well! The taste isn't bad at all and Crest is a trusted brand. Had my teeth whiter in less than a week. Usually teeth whiteners leave a calcium spot on my tooth but this one, to my surprise, didn't. Would recommend!

I use these whitening strips about twice a year (I love my wine and coffee lol) I definitely see s huge diference after the 4 th day and by the 7th day my teeth look like they've been whitened at a doctors office

They work great! I use these occasionally every few weeks to a month at a time to help keep my teeth nice and white! They do make my teeth a little sensitive at times if I use them for too long or too often but other than that great results.

These work great on my teeth. I will be 40 this month and by using these strips they make me look late 20's. Do not use over 15 minutes. I only use 10 minutes myself because of the sensitivity.

Instant results even after just one use! I use these every night before bed and my teeth look so much better! They also do not make your teeth sensitive to cold foods or drinks! I love these white strips
