Is it okay to use 3D White Whitestrips kits back to back? 
Yes. With Crest 3D Whitestrips, you can use one strip right after the other (back-to-back). Wear strips for the instructed time, then remove; rinse or wipe if needed, then apply a second strip. To maintain your whiter smile use up to two Crest 3D White Whitestrips teeth whitening systems per year.

How do I Store my Teeth Whitening kit?
Most manufacturers recommend storing tooth whitening kits in a cool place. What does this mean? Anywhere in your home where heat isn't trapped in a confined space can be a great place to store tooth whitening kits when not in use.

For some, under the bathroom cabinet or in a linen closet is appropriate. Others who live in extremely warm climates may want to store tooth whitening kits in the refrigerator.

You may wonder if the steam and heat generated by bathroom showers will cause problems for your tooth whitening kits. But the limited amount of heat generated in these situations shouldn't have any negative effects on tooth whitening kits.

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. 

Crest® Whitestrips can be an affordable way to get the same results you might get from a more expensive treatment. While Crest Whitestrips may initially cause gum discomfort or tooth sensitivity due to whitening, these effects are temporary and have no long-term adverse effects. If you’re experiencing sensitive teeth due to whitening, try waiting a few days before your next treatment.

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.

I have been using

I have been using crest whitening strip for years and I swear by them. My teeth could not be any whiter and brighter. I usually leave these on for about an hour (longer than recommended) and I instantly notice a difference, and my teeth continue to get whiter as time goes on.
