I have been using Crest 3 D whitestrips for less than a month. By my 4th treatment my yellow teeth were WHITE! I smile all the time now. I haven't smiled with my teeth showing for over 20 years!

I bought the box of 20 treatments--40 strips. Used them faithfully each day, and was hoping for at least SOME whitening. What a waste of money! My teeth look exactly the same as before using the strips.

For the past 3 months I've been using this toothpaste. its absolutely the best. my teeth look and feel healthy, And to mention the whiteness of my teeth. every time I smile my teeth shine bright like a diamond!!

I mean, I’m sure that it works great for people with normal teeth. I however have very sensitive teeth, and found extreme amounts of pain when using these. Absolutely NOT for those with sensitive gums. I had pain for hours after.

These definitely work! I used these for about two weeks and seen a major difference I was actually shocked! They are pretty affordable and they do wonders! Highly recommend!

I only gave this product a 3 because my teeth are super sensitive and this product gave me pain for 24 hours after use. I did notice a difference in my teeth but not worth the pain!

Liked using these for a short period of time but they do cause my teeth to be super sensitive afterwards which is expected but not super ideal for me.

I didn’t really have a great experience with these. They tasted really bad and didn’t show any effectiveness on my teeth. I honestly think the off brand did better for me. Won’t by again.

They are very effective. I was surprised that they actually whitened my teeth quite a bit especially for the price point. I recommend them for sure and I will keep buying them.

My husband and I really wanted to whiten our smiles! We have noticed there are some strips that grip your teeth better than others. These were great! We noticed a difference in a week!
