This whitening kit is by far my favorite. I love these they don't hurt for sensitive teeth and leave my teeth looking red carpet white. They are not too expensive but for the price i would say you cant find any better! My whole family uses these and all of them approve as well!

I recently tried these for the first time. I heard that my teeth become sensitive but they didn't. I would say that my teeth went from not white to semi-white. Overall I'm satisfied but I definitely need to buy again and do a second time to get the full effect.

When I quit smoking I tried everything To get rid of cigarettes stains. Even with regular dental visit and cleanings the stains remained. I tried all kinds of Tothpaste. No help. After 5 packets the Stains are almost gone. I still have several to use and another box. Thanks

These whitestrips helped me so much! I'm so happy I got them I don't regret it at all! I used to be really self-conscious about my teeth and I wasn't as confident as I am now. I love to smile now more than ever because i'm happy with how white my teeth are. I really recommend this to anyone who is looking for whiter teeth. I hope this review helps you make the right choice! good luck!

I've never seen anything work this well on my teeth! At first I'd lost hope and believed that my teeth would never become white but after using Crest 3D white strips I was given a healthy, clean, and sparkly smile. For a professional smile, get Crest 3D White Strips and you'll never be disappointed.

I've been using Crest strips for as long as I could remember . The product just gets better and better. I love the grip that they offer now. Everyone always asks me how do I get my teeth so white. I use the whole line for maximum results. Well worth the money!

I use the crest whitening toothpaste which works great alone but if I have a special occasion coming up or just want that extra oomf I use these and my teeth stay looking white for about 2 weeks. But I drink coffee a lot so that probably doesn't help.

I like the fact the strips stay in place and you can go about your normal business. I've even taken them to a girls day to share. I do wish they were wider to fully cover the back of the teeth as well. This is my preferred brand and have purchased them several times.

I LOVE this product! The first time I used it, I didn't notice a major difference; however, as I continued to use it I noticed my teeth got significantly whiter! I used the treatment several times in preparation for a photo session, and I was so happy with the results. If I leave it on for too long, my teeth can feel sensitive after use, but it's never for long and the payoff is worth it!

I bought Crest's Professional Effects Whitestrips to brighten my smile before my wedding day because I had accumulated some brown coffee stains around my front teeth. I did three days of the whitestrips and was very pleased with the results! I would recommend these whitestrips to anyone wanting to get rid of stains and brighten their smile a few shades whiter.
