Crest3D Whitestrips Sensitive At-Home Teeth Whitening Kit, 18 Treatments, Gently Removes 15 Years of Stains, Crest Whitestrips, Teeth Whitening Kit

this was the first time I have ever tried to whiten my teeth. I am 91 years old and noticed that my teeth looked dingy. One of my front teeth is an implant and it was noticeably whiter than the rest of my teeth. After using this for the full 18 treatments my teeth were not sparkling white,, but were definitely whiter and the implant blended in and my smile looks better. There was no irritation when using the strips. I will use this again in the future.

Definitely for sensitive teeth (which we have); they don't bleach out as quickly, but one wouldn't expect to when they don't hurt. LOL. They work nicely over time but you may find (like we did) that you have to use the entire pack to get to your whiteness level. In all, good value, good purchase, work well.

Edit 5/25/25 : I will buy them again!I didn't used them every day. Maybe 5 days in a row at first, then once every 2 weeks maybe. But it's because they work and have worked for me. My teeth aren't SUPER white, but they are not the stained yellow they once were. I've even gotten a couple compliments on how my teeth are white. So maybe my teeth aren't super white to me, but others notice. So they work! My teeth also haven't experienced any sensitivity. People are complaining, saying these strips aren't the sensitive ones but I think they are, although my actual strips are in the same blue wrapping people keep posting. It's possible they swapped the wrapping, companies change things all the time. Don't let the negative comments deter you, catch them on sale, try for yourself, don't use them every single day if you're nervous. But I will be buying them again, no doubt. Also, I'm a harsh critic so they're alright with me 👍🏾Orginal 2/25/25Order was delivered this morning and I used it right away. I was hoping for results but not expecting any because of previous experiences with other whitening gels. I took a pic of my teeth beforehand and I followed the directions and left the strips on for 30/35 minutes. I brushed my teeth shortly before because I didn't see the warning on the box that said not too. (Oops.) But my teeth are a shade whiter from just the one use! It's a subtle difference but a difference nonetheless. I also took an after pic so i know my mind isn't paying tricks on me. I can't wait to see my 7, 14, and 18 day results but if it's whitening this well, I may not need to use the entire box for the next 17 days. I hope it continues to work for me. It's worth a try especially when you can catch a sell for $24. Give it a try.I will update review with final results.

The whitening strips worked well with any irritation of my gums. No nasty taste and rinse with easy after removal. I usually brush with Baking Soda, then toothpaste. It made a great improvement whitening my teeth. Highly recommend this product.

As far as the product goes, this works for me. One reviewer suggested to cut them lengthwise in 1/2 so you can use one piece twice. This was a good idea, although I don't do it as often as I can. Overall, a very good product and I have noticed some whitening. I don't use them everyday, and they do not bother my teeth at all.However, the box arrived smashed.

This was my first time using whitening strips, so I decided to go with these since they're made for sensitive teeth. Normally, I don't have problems with sensitivity, but after a few sessions I definitely started feeling a bit of sensitivity. They did whiten my teeth a few shades. Decent results but nothing too dramatic. They were pretty easy to apply but not so easy to take off, since the gel gets very sticky.

I’ve always wanted whiter teeth but was worried about sensitivity. And damaging my teeth, These Crest 3D Whitestrips for sensitive teeth surprisingly work They’re gentle yet effective, and I noticed a difference after just a few uses. After completing the treatments, my teeth looked brighter and stains from coffee and tea were noticeably reduced. But not fully white though The strips are easy to apply and stay in place well, so I can go about my routine while wearing them. As in the shower and also I did not have No irritation or discomfort, which is a huge deal for me so overall it gave my teeth a nice whiter look

Really works. I started seeing results in 3 days. I’m on my 8th day and I’m pleased with the result. It’s worth trying.
