A bit pricey but I recommend everyone trying these before getting a professional teeth whitening job done. They are super easy to use and definitely work over a period of weeks. I usually have some left over in the box after purchasing that I can touch up with.

I have been using Crest white strips for YEARS! I love how they keep my smile bright and I always get compliments on how white my teeth are. I personally have to use the kits that take a couple of weeks due to my teeth sensitivity but it's always worth it!

I ran into my eldest sister years ago smiling (she doesn't normally show her teeth) but as soon as she smiled at me I KNEW she had been to the dentist, but boy was I wrong! She had introduced me to crest 3d professional effects and since then I have been hooked!! I cannot believe that they actually work!! I drink a lot of coffee and was a smoker for years and I can use a strip a day for a couple of days and my teeth are pearly white!! Even just one strip makes a huge difference!

The best at home whitening! I usually split the box into two separate treatment's worth so I have more for my dollar but also not using too long to cause too much sensitivity. I usually get sensitivity to my teeth while using this about 8 hours after I finish, so I usually do at night before bed that way it never effects my eating or drinking!

I have been using these white strips for years and I love them!! They are so easy to use, and leave your smile so much whiter and brighter. I've gotten so many compliments on how white my teeth are and it is all from using this product matched with a whitening toothpaste!! I highly recommend.

I received these in a brown box with no instructions. I'm not sure how often to use them or if I start with Supreme Bright or Professional Effects. Is there any way to get the instructions? I rated "Poor" because I was required to pick one, but I have no idea if they work or not.

I recently had the fortune of sampling Crest's 3D White Strips and I am SOLD! They have done away with the messy residue! The strips are easy to apply and stay on without moving or becoming uncomfortable! My teeth are noticeably whiter! The new white strips are easy to apply, comfortable to wear, and leave no mess or bad taste in your mouth. I have already recommended them to friends and family and will definitely be a repeat buyer!

I just like how easy they are to use. If you have sensitive teeth these are not for you. They meet my expectations. I wish the strips to be a bit longer on both the top and bottom. I use these about 1-2 a month. I definitely recommend to others, but be warned... they are not cheap.

The Crest 3D White Radiant Express Strips work really, really well. My teeth look whiter just after using it a few times and I'm excited to see the results after the full 14 day treatment course. The strips are very easy to apply, they peel off easily and adhere to teeth without slipping. I didn't have any problem keeping them on my teeth for 1 hour, while I worked around the house. After I used them a couple days in a row, I did notice mild tooth sensitivity but it resolved as the day went on. I did take a break for a day from using the strips and it didn't happen since. I would recommend using these strips every other day or every few days if you have sensitive teeth to avoid sensitivity. These strips absolutely work great at whitening teeth. So effective and much cheaper than going for a whitening treatment at the dentist. I absolutely recommend these strips for at home teeth whitening!

I had a chance to try Crest 3D Whitestripsin the weeks approaching my step daughter's wedding. I absolutely loved the results! Not only were they easy to use, but the wedding photos turned out great with my gleaming white teeth! I had several people say how much younger I looked!
