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.

These work very well

These work very well for me. I try to do them once or twice a month and I notice that my teeth are whiter. However, it does cause my teeth to be sensitive to cold drinks.

The white strips are

The white strips are literally the only teeth whitener that has worked for me through the years. I used to smoke so my teeth were honestly yellow at one point. The only thing that helped whiten them was this!
