I have used Crest whitening strips for many years and I must tell you, they are the only strips that work really well as compared to the other brands out there. Also, they are a lot less expensive than the whitening procedures at a dental office. I always recommend these to my friends and family to use.

I have been using Crest Whitestrips for years, and I have received a plethora of compliments about my teeth being so white. I can recall receiving my first compliment about how white my teeth were after the second day of using the product. I knew then that I was going to be a lifetime customer. I am so grateful to express my sincere appreciation for your company creating Crest Whitesrips. I will definitely recommend Crest Whitestrips to others for the rest of my life. Thanks to Crest Whitestrips, I have a whiter brighter lifetime smile.

The best way to whiten your teeth! I get comments all the time for my white teeth and my dentist actually told me that I have a "movie star smile." You don't have to use them all the time to get results either. I used them every few days at first but now I only use them every few months. Highly recommended!

I know a lot of people have talked about this product having the possibility of ruining your enamel and making your teeth more sensitive, but coming from someone who has both sensitive teeth and gums, this product gave me 0 problems and 100% satisfaction. It is definitely on the pricey side but one box, or at least 10 treatments will hold you solid for a long time. It’s a great investment and made me all the more comfortable with smiling!

I really like this product and it was recommended to me by others. It made my teeth really white which I love! I have sensitive teeth so if I need to space it out between using. It can hurt your teeth if you use it multiple times a week. It’s worth the price because it comes with so many!

I had a chance to try Crest 3D Whitestripsin the weeks approaching my step daughter's wedding. I absolutely loved the results! Not only were they easy to use, but the wedding photos turned out great with my gleaming white teeth! I had several people say how much younger I looked!

I want to love this product but unfortunately my teeth gets really sensitive to this. It's hard to eat or drink anything cold the next day. Even sucking cold air into my mouth is sensitive. I wish there were more options for people with sensitive teeth. 

Literally wearing these as I type this! I’ve suffered with yellow teeth from drinking too much soda as a child. These are my favorite things because they have helped me 100% be confident in my teeth! I don’t have to hide my teeth when I smile anymore.

These work but I will remove one star for the sensitivity after using. Any drink, hot or cold, will feel strange against your teeth after using. Make sure you only leave them on as long as instructed. Hard to attach the bottom strip and it doesn’t conform well to your teeth.

Hace dos meses empezamos a usar estas tiras,mi esposo tenia los dientes muy amarillos y en 3 semanas sus dientes se aclararon mucho,él está muy feliz pues un blanqueamiento en el dentista es super caro,en cambio en mis dientes no he notado mucho cambio,quiza porque los mios no han estado amarillos,pero tampoco son super blancos,al menos sé que funcionan y no nos produjo ninguna sensibilidad ni dolor y lo malo es que no siempre pegan bien,algunas tiras parecen no tener mucha fuerza para pegarse a tus dientes y se resbalan
