Pro formula teeth whitening strips
Whitening strips use peroxide gel on tooth surfaces, and the product, fit, and wear time matter more than a professional label.
The short answer
A whitening strip is a flexible carrier coated with a peroxide-based gel. The gel can lighten some stains within natural enamel and dentine, but it does not change the colour of fillings, crowns, veneers, or bonding, and it cannot remove tartar.
What is the direct answer?
What does this question mean?
Brush gently, dry the teeth if the instructions require it, place the strip without covering the gums, and follow the package schedule. Stop if the gums burn or teeth become painful, and have cavities, cracks, gum recession, or existing sensitivity assessed before continuing.
What can you do next?
See a dentist for persistent sensitivity, gum injury, uneven darkening, or a single grey or brown tooth. Dental examination is also appropriate when stains may be tartar, fluorosis, medication-related, or internal to the tooth rather than surface stain.
When should you seek dental care?
Ask which stain type is present and whether the strip contains peroxide. Ask what wear schedule fits your teeth and how existing restorations will look beside the whitened enamel.

Frequently asked questions
What is the first practical step?
Use the page-specific care measure and arrange an examination if the symptom persists or worsens.
Can home care replace an examination?
No. Home care may reduce irritation, but it cannot diagnose or repair decay, cracks, infection, or gum disease.
