FAQs


Can I Use More than 2 Sets of Whitestrips a Day?

Extensive clinical and consumer testing was done to establish the safety and efficacy of Crest 3D White Whitestrips. However, based on the results of that work we do not recommend using more than 2 upper strips and 2 lower strips in a day.

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 Wear Whitestrips Overnight While I Sleep?

No, do not wear Whitestrips overnight or while sleeping.

Are Crest Whitestrips Safe?

Crest Whitestrips are also 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. In fact, Crest Whitestrips Whitening + Therapy also strengthen your enamel with a soothing serum.

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 Brush My Teeth Before or After Using Whitestrips?

After

Yes, after using Whitestrips, you can brush gently.

Before

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. 

Will Crest 3D White Whitestrips Affect My Dental Work?

Crest 3D White Whitestrips will only whiten natural teeth. The strips will not whiten caps, crowns, veneers, fillings or dentures. Do not use with dental braces. If you are in need of dental work, have dental work or have staining from medication, ask your dentist to determine if whitening is appropriate. Crest 3D White Whitestrips Classic Vivid and Professional Effects Whitestrips are designed to hold well to teeth, do not use on loose teeth or temporary or loose restorations.
