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.
How should you place and use whitening strips?
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.
When should persistent whitening problems be checked?
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.
Which stains need dental assessment before using strips?
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.
What active ingredient does the whitening strip contain?

Frequently asked questions
What should you do if whitening symptoms persist or worsen?
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.
