The short answer
Whitening strips use a peroxide gel on the tooth surface to lighten some stains, but they do not repair decay, restore enamel loss, or change the colour of fillings and crowns.
What is the direct answer?
What does this question mean?
A whitening strip is a flexible carrier coated with bleaching gel that contacts the front teeth. The result depends on the type of stain, enamel condition, exposure pattern, and whether restorations are present.
What can you do next?
Follow the product directions and stop if marked sensitivity or gum irritation develops. A dental examination should come first when teeth are painful, cracked, decayed, or heavily restored.
When should you seek dental care?
Seek dental care for persistent sensitivity, gum burns, toothache, swelling, or a single tooth that darkens. These findings may reflect disease rather than a cosmetic stain.
What should you ask the dentist?
Ask whether your stains are suitable for peroxide whitening, whether fillings will match afterward, and how to manage sensitivity.

When should I arrange an examination?
Seek dental care for persistent sensitivity, gum burns, toothache, swelling, or a single tooth that darkens. These findings may reflect disease rather than a cosmetic stain.
