Convenient, Safe & Controlled

Crest Whitestrips are comprised of thin, flexible strips that are coated with a tooth whitening gel containing peroxide. Designed to conform to the shape of your teeth, they work by keeping the whitening gel on your teeth for the instructed amount of time to provide fast whitening. Whitestrips have the whitening gel already added to them so they deliver a consistent, controlled dose each time. Strips do not have to be loaded before every use, unlike trays, which can cause oral irritation if too much gel is added.

• Strips are ready-made so you can use them right away. No dental impressions required
• At home or on the road, strips are portable enough to be used anywhere, at any time during the day
• Pre-filled strips to control dosage
• Reduces gel from going over gums
