The short answer
Whitening strips use a peroxide gel to oxidize some stains on the outer tooth surface, while fit and gel concentration affect sensitivity and gum irritation.
What is the direct answer?
What does this question mean?
The number in a product name is a marketing or formulation label, not a clinical diagnosis. Strips contact enamel but cannot whiten fillings, crowns, veneers, or the darker root surface exposed by recession.
What can you do next?
Read the package directions, keep gel off the gums, and stop if pain or burning develops. A dental examination before whitening can identify decay, cracks, gum recession, or restorations that need attention first.
When should you seek dental care?
See a dentist for persistent sensitivity, gum burns, uneven colour, darkening of one tooth, or whitening needs when you have extensive restorations.
What should you ask the dentist?
Ask what the active peroxide is, whether your restorations will change colour, and whether custom trays or in-office whitening better fit your teeth.

Home care can reduce irritation or symptoms, but it cannot diagnose or repair every dental cause.
