My brother used to use these and every time I he'd visit his teeth would catch my eye because of how bright they were. He recently gave me three of these and I've definitely noticed some results. I didn't brush my teeth for a year or so when I was younger so it's really reassuring to know there's something that could quite possibly fix the damage my younger self did to my teeth.

[This review was collected as part of a promotion.] I feel so lucky we got to try these strips. My daughter just got her braces off and used these to whiten around where her braces were. After a few days she has noticed a difference. The packaging is cute and my daughter is displaying them on her vanity:

[This review was collected as part of a promotion.] Crest 3D Whitestrips Professional Effects are an easy and effective way to get a noticeably whiter smile at home. They're simple to use—just apply the strips, wait about 45 minutes, and peel them off. I started seeing a difference after a few uses, and by the end of the treatment, my teeth looked significantly brighter. The strips are almost flavorless and stick really well—almost too well! I really have to peel them off, but at least that means they stay in place and do their job. Each box contains enough strips for 18 treatments, making it a great value for long-lasting whitening. It's a simple and effective way to whiten your teeth while relaxing at home. The only downside is they can cause some sensitivity, but the results are noticeable and worth it. If you're looking for an at-home whitening option that really works, these are a great choice!

[This review was collected as part of a promotion.] Starting off strong with a simple yet attractive package that is easy to open! The strips are super easy to remove from packaging and apply to your teeth. Directions are simple and the results are amazing. You wear these for 45 minutes at a time and after just the first use, I definitely noticed improvement in whitening on my teeth! happy to say that I haven't noticed any tooth sensitivity so far after 3 uses now! The strips stay stuck to your teeth during the full 45 minutes, which is awesome because there has been other ones that stay very slippery and tend to slide off

[This review was collected as part of a promotion.] I absolutely love these Whitening strips from crest. They're very easy to use and very comfortable to wear. Also my teeth didn't get sensitive with these which is great and the packaging was easy to use. Overall, I would highly recommend these strips and they work fast and work really well. If you have a special occasion, and you would like to whiten your teeth, these are the whitening strips for you!

I bought these for my husband who decided to whiten his teeth after using chewing tobacco for 17 years. His teeth were actually stained brown. Within 1 day we saw a difference, and by the time he was finished there were 17 years of chew tobacco stains completely gone. Fantastic, impressive results!

[This review was collected as part of a promotion.] Have been using this brand for years. I like the way they worked after just one use, I noticed that my teeth was way whiter than they were before treatment. Easy to apply and remove. Overall, great product, good price and nice packaging.

[This review was collected as part of a promotion.] The Crest 3D Whitening Strips are incredibly easy to use and are designed to adhere securely to your teeth. To apply, you simply peel off the clear liner, place the strip on your upper and lower front teeth, and press it gently to ensure it stays in place. After 60 minutes, you just peel the strip off, and removing it is a breeze. I then brush my teeth to remove any remaining ingredients. From the moment I place the strips on my teeth, I notice a cooling sensation, which leaves a feeling of freshness in my mouth. The strips feel comfortable and stay securely in place for the full 60 minutes, with no discomfort. There is no aftertaste, and the taste is neutral, which makes it very comfortable to wear during the whitening process. I was genuinely amazed by the results after my first use. My teeth appeared visibly whiter compared to before, and I could see the effectiveness of the whitening process after each use. The more I used it, the more noticeable the difference became. The packaging includes information about the ingredients, which contain the same safe whitening agents used by professional dentists. This product is an excellent choice for at-home teeth whitening if you're looking for noticeable results. I've experienced no tooth sensitivity or gum discomfort while using these strips, which is a huge plus. The ingredients include water, hydrogen peroxide, sodium hydroxide, and acrylic copolymer. If you're concerned about sensitivity, it's always a good idea to check the ingredients list, but I've had no issues with them so far. Overall, I highly recommend Crest 3D Whitening Strips for anyone looking for an effective and convenient at-home whitening solution. The results are impressive, and the experience is comfortable and easy to follow.

[This review was collected as part of a promotion.] I absolutely love these! I will start by saying I have very sensitive teeth, and I had no issues with this product! They were so comfortable with zero sensitivity problems. They apply easily and bend right over the teeth so they can be fitted properly. Once applied they stay put without slipping! One hour a day for one week, and my teeth were SEVERAL shades whiter! My teeth are glistening like they did when I was a teenager! I'm a coffee drinker….. like a constant coffee drinker, so I struggle with coffee stains. Well, no more thanks to these! I cannot wait to use them again!

[This review was collected as part of a promotion.] Thanks Influenster, for the free Crest 3DWhitestrips.. the packaging was not great, but that may have been due to shipping. These strips worked ok, I noticed a slight difference. I dd have a slight sensitivity to it.
