Can I Wear the Strips Longer for Better Whitening Results?
We recommend following usage instructions for each product. Longer wear time can result in tooth sensitivity and/or gum discomfort.

Can I Brush My Teeth Immediately After Using Whitestrips?
Yes, after using Whitestrips, you can brush gently.

Can I Brush My Teeth Immediately Before Using Whitestrips?
Do NOT brush immediately BEFORE applying strips. To avoid gum irritation, allow for some time to pass after you have brushed your teeth to apply strips.

Are Crest Whitestrips Safe?
Crest Whitestrips are proven to be safe, as research demonstrated through extensive clinical trials. Whitestrips use the same enamel-safe ingredient, hydrogen peroxide, which many dentists use in their offices.

Can I Store Whitestrips in My Refrigerator or Freezer?
Storing Crest 3D White Whitestrips in a refrigerator is fine, however, storing product in a freezer is not recommended.

Can I Use Whitestrips if I Have Braces?
Crest 3D White Whitestrips should not be applied to teeth with braces because Crest 3D White Whitestrips will whiten only the portion of the teeth with which the whitening gel comes in contact.
Because braces cover some areas of the tooth surface only parts of the tooth will whiten, leaving unevenly colored teeth when the braces are removed. In addition, metal in the braces could oxidize and change color.

Can I Use Whitestrips if I Have a Cavity?
If you have an unfilled cavity, we do not recommend using Crest 3D White Whitestrips. Check with your dental professional before using a whitening product if you are in need of dental work.

Can I Use Whitestrips if I Have Gum Disease (Periodontal Disease)?
Do not use Crest 3D White Whitestrips if you have gum disease (periodontal disease). Talk to your dental professional about treating your periodontal disease first, before you ever consider whitening.

Great product!

I'm over 60 and had never had my teeth whitened. Frankly I wan't expecting much. Wow....nice difference after using these! My teeth are quite crooked so I didn't want anything that utilized a tray, but these strips get where they're supposed to and stay there. I used the strips twice the first month and then once a month... great results! My wife and daughters commented on how much whiter my teeth became. I will never have super white "Hollywood" teeth (something I think looks unnatural), but these strips have done an amazing job!

Yes, I recommend this product.

I have been using these once a year for the past three years. I constantly get compliments on my smile and how white my teeth are and they were pretty stained until I starting using these. Dramatically whitens without gum sensitivity

Yes, I recommend this product.

This product does exactly what it says.

I was considering doing a $500 treatment until I heard about this product with such great reviews. I saw results after the first day and definitely saw an improvement after the two weeks. Now everyone compliments me on my whiter smile :)

Yes, I recommend this product.
