Keeps my teeth lighter than they would for all the coffee and tea I drink. I whiten my teeth at the dentist before but these strips do a good job without the expense. I do occasionally have some difficulty with them staying in place but not often.

My dentist recommended I try Crest white strips. They fairly expensive so I checked Sam's and they were $49.95 for 20 sets you use for 20 days and 11 sets you use once a month. They work. My teeth are starting to look whiter after 5 days. I recommend them. Great value.

These work just as good as what you would receive at the dental office.

Worked great. I have been told my teeth are permanently discolored by a medicine I was given as a child. I tried whitening strips years ago with not much luck. I decided to try again. I saw a noticeable improvement. I already purchased another box.

Stunning! They truly whitened my teeth! My teeth did get a little sensitive but my dentist just said swipe some Sensodyne on them and let it set. All good!

Definitely whiter teeth. This kit has 20 days everyday and then 11 maintenance strips once monthly for a hour. I’m on day 13 already and my teeth are so much whiter even the lower part of my bottom teeth. This kit was a great idea and works well. Definitely recommend this kit.

The strips work, but can be tricky. You need to dry your teeth as much as possible before using the strips and they don’t go over your molars. They do brighten your teeth quite a bit though.

Works well, not as white as I hoped but definitely an improvement. The top stayed in place the bottom did not and were difficult to apply.

1. Crest 3-D white stripes are expensive per each use. 2. They were difficult to use, and I repeatedly had problems trying to keep the bottom strip on my teeth. Three times the strip would not stay on my lower teeth, and I had to throw it out making each treatment even more expensive. 3. Each time I use the crest 3-D strips, my teeth became uncomfortably sensitive and remained so for about two days. 4. In fairness, I do have acid erosion on my teeth that could have contributed to the sensitivity. However, I have used other whitening products that did not cause the sensitivity that I experienced with crest 3-D strips. 5. I won’t buy these strips again and am considering returning them to the store.

Doesn’t really work to whiten
