Whitening strips are thin plastic carriers coated with a peroxide-based gel that contacts the front surfaces of teeth.
The short answer
Whitening strips are thin plastic carriers coated with a peroxide-based gel that contacts the front surfaces of teeth. Their result and side effects depend on the formulation, contact time, tooth condition, and correct use.

What is the direct answer?
What does this question mean?
Peroxide oxidizes some stain molecules within enamel and dentine, while it does not change the color of fillings, crowns, veneers, or other restorations. Uneven results can occur when teeth have different restorations, decay, cracks, or intrinsic discoloration.
What can you do next?
Use the product exactly as directed, keep gel off the gums, and stop if significant burning or pain develops. A dental examination should come before whitening when there is decay, gum disease, exposed roots, cracks, or marked sensitivity.
When should you seek dental care?
Seek dental care for persistent sensitivity, gum whitening or peeling, pain, or an uneven dark tooth. Whitening should be postponed until untreated disease and defective restorations have been assessed.
What should you ask the dentist?
Ask whether the tooth surfaces and restorations are suitable for whitening. Ask which concentration and wear schedule fit your sensitivity and what shade change is realistic for your natural teeth.
