Hismile strips before and after
Whitening-strip results vary with starting shade, stain type, fit, wear pattern, lighting, and whether teeth are natural or restored.
The short answer
Before-and-after photographs cannot predict an individual result because lighting, dehydration, and camera settings change appearance. Strips do not recolour fillings, crowns, veneers, or bonding.
How does peroxide gel work during strip treatment?
Peroxide gel contacts facial enamel for a defined wear period. Follow directions, keep gel off the gums, and stop if marked irritation or pain develops.
What should be checked before you use whitening strips?
A dark single tooth, decay, cracks, gum disease, or severe sensitivity should be assessed before using strips.
What should you ask about stains and restorations first?
What type of stain is present, and how will existing restorations look after natural teeth lighten?
