Common FAQs About Crest 3D Whitestrips

How do Crest 3D Whitestrips work?

Crest Whitestrips use a peroxide-based gel that adheres to the front surfaces of teeth. The gel penetrates beneath the enamel to help break down stains and gradually whiten teeth with consistent use.

Will Crest Whitestrips cause sensitivity?

Some users may experience mild, temporary tooth sensitivity or gum discomfort, especially with higher-strength formulas. If sensitivity occurs, pause use for 2–3 days before resuming.

Can I use Crest Whitestrips if I have dental work?

Whitestrips are designed for natural teeth only. They do not whiten crowns, veneers, fillings, or dentures. Speak with your dentist if you have extensive dental restorations.

Are Crest Whitestrips safe for enamel?

Yes. Crest Whitestrips use the same enamel-safe whitening ingredient dentists use. When used as directed, they are clinically tested and safe for tooth enamel.

Why do white spots appear after removing strips?

Temporary white spots may appear immediately after whitening. These usually fade within a few hours and are not harmful.

What if I have trouble removing a strip?

Peel the strip from the back of your teeth first to loosen the grip, then remove the rest gently.

How often should I use Crest Whitestrips?

• One treatment per day per kit is recommended

• Use up to two kits per year

• Some formulas allow twice-daily use — follow product packaging instructions
