These are amazing. Everyone should purchase this product! Crest whitening strips work wonders and actually make teeth whiter. They are kind of pricey but super worth it in my opinion! I am a coffee addict so these whitening strips are a staple for me.

I absolutely love my Crest 3D White Luxe Professional Effects Whitestrips Teeth Whitening Kit I use this when needed. You can tell the difference with one time used. I've been using this for years and and very effective. Please a reminder don't let it sit too long because your teeth can get too sensitive. I leave it on for about 20mins.

3D Whitestrips professional effects to your oral-care routine for: • Professional teeth whitening at home. • Results last up to a whole year. • Apply daily for 30 minutes. • Advanced Seal's technology, no-slip grip, stays put so you can talk and drink water while whitening your teeth. • 3D Whitestrips use the same enamel-safe teeth whitener that dentists use. 3D Whitestrips allow you to see results after 3 days, with full results in 20.

Legit the best whitening strips I've ever used. They made my teeth go from yellow to this beautiful natural sparkling white. I'm no longer insecure about my smile or if the color of my lipstick is making my teeth look even worse. I experienced no sensitivity and will definitely be repurchasing

I really did like this product. Drink coffee and I do smoke so as a dental assistant I felt like my teeth could be whiter and I purchased and I did see a difference with in a week I did get sensitive to it so I had to get toothpaste for that but it does work and I do record as long as YOU DONT HAVE resin fills or crowns in front teeth as those will NOT change colors and it will stand out as your teeth get whiter.

My main resining for loving these is because they don't budge when on the teeth! These whiten more “over time” not a one time use kind of a thing. But I always get compliments on my teeth and when I tell people what I do different, I usually get a response in a few weeks saying these strips are working great for them too!

Absolutely wonderful! These whitening strips whiten teeth instantly. Although using them day after day can lead to teeth sensitivity, they are still my go-to! I would suggest not using them daily & spreading out the usage. The effects are long lasting!

I used to use Crest strips before and wanted to order these. As previous reviews have mentioned, this came in a brown box with no instructions - just the strips. I opened two of them and they are dry and have no whitening gel at all. I basically paid $40 for tape.

I've used these in the past and had great results. My teeth remain white and every once in a while I will re use for maintenance. The only con is the sensitivity. I would honestly use them more often if they didn't cause my teeth to feel so uncomfortable. The sensitivity goes away within about a week of ending use though.

This was the first product of this kind that I tested and needless to say that I did not need to look further. I took pictures after everyday that I used this and there is already a very noticeable difference between the first day and the third. I used it once every week and for an hour. It left my teeth sensitive, but not too much and it was probably because of the amount of time that I used the strips.
