Offers great value, but can be pricey for some.

Simple application process with minimal effort.

May not effectively alleviate sensitivity issues.

These flexstrips work great! My teeth were very yellow and after using these they have never been this white.Will buy again in about a year and use the cheaper strips in between.Also brushing with whitening Toothpaste and whitening mouthwash which seems to be helping after 3 weeks.

Great purchase

Very good products,  it really does a good job

Great products

These whitening strips actually work.  I've bought other types -- including other Crest products -- but these are by far the only ones that have made a noticeable difference.

Expensive but worth the investment

[This review was collected as part of a promotion.] I love these crest whitening strips, I've been using different variants of them for 15 years now, they're fantastic! I will say, I wish the box was smaller. You get plenty, but the box is way bigger than necessary. It would be easier to store them if the box was smaller. But the product itself is fantastic!

Great product

influenster.com

[This review was collected as part of a promotion.] I have not used crest whitening strips in years. They have definitely improved. I love these strips. They're easy to apply, just peel the strips off the plastic and place onto teeth. You leave them on for an hour and then peel off.  I love that they stay in place the whole time. I noticed that my teeth looked whiter after just a couple uses. Crest is my definite go to for dental needs.

Great stay in place whitening strips

[This review was collected as part of a promotion.] These whitening strips I received from Influenster in exchange for my honest review have been a miracle for my teeth. I've been struggling with wanting whiter teeth for awhile now. Since using these I've seen a drastic change in my teeth coloration. 
These are simple and easy to use and works exactly how I expected them to. I love these!!

Cool

crest.com

[This review was collected as part of a promotion.] I received these Crest 3D Age Renew Whitestrips for free from Influenster and Crest in exchange for my honest review. First off, I love how quick and easy these whitestrips are to apply! Plus, they actually stay on really well and they do not leave a yucky taste in your mouth. Just one hour every day for 21 days and my smile is noticeably brighter and whiter! Yay! 😁 I would definitely recommend giving these Crest 3D Age Renew Whitestrips a try!

Great results + easy to apply

[This review was collected as part of a promotion.] I used this for 4 days in a row and a portionj of my gums got irritated.   It does whiten real good.  I took a break and made sure it wasn't touching my gums.  It was ok then.   It does whiten and get out stains.

It does whiten but some people may be sensitive to

[This review was collected as part of a promotion.] Love these whitening strips! My teeth definitely looked whiter after only 7 days! The packaging is nice and I love the value! The only thing for me was that my teeth were really sensitive after I used them. I had to use sensodyne toothpaste after. Other than that, they are amazing!

Will use again!

[This review was collected as part of a promotion.] I recently tried the Crest 3D Whitestrips Age Renew, which promises to reverse years of staining and brighten teeth up to 25 levels. The kit includes 21 treatments (each with upper and lower strips) and is designed to fight age-related yellowing for a naturally radiant, younger-looking smile.


While the product aims to provide a professional-grade whitening experience at home, I found the application process somewhat challenging. The strips require completely dry teeth to adhere properly, at least, it did for me,  which can be difficult to achieve. Even then, they tended to slide around during use.

I used the treatments every day,  and did notice a visible improvement in the whiteness of my teeth. However, despite claims of being enamel-safe and designed for aging teeth, I experienced slight sensitivity after use.


Overall, the Crest 3D Whitestrips Age Renew offers a convenient at-home whitening solution with noticeable results. However, the application issues and minor sensitivity I experienced may deter me from repurchasing this particular product.

Good, But Not For Me

[This review was collected as part of a promotion.] I didn't try this personally because I have sensitive teeth. However I have t to a friend to try and they said it was just ok. They said the gel was frustrating to wipe off, but not excessive. And sometimes the strip that folds over sometimes pulled a bit (not as secure) when talking. 

Enough packets came in the box. Easy to carry around. Simple instructions.
