What are BlanX O3X Flash White Strips used for?

BlanX O3X Flash White Strips are peroxide-based home whitening strips that contact the front surfaces of natural teeth.

How does whitening gel work on natural tooth enamel?

The strip holds whitening gel against enamel, where peroxide can break down some stain molecules. Whitening changes natural tooth colour, not the shade of fillings, crowns, veneers, or other restorations.

How should you use whitening strips safely at home?

Follow the product directions, keep gel off the gums, and stop if marked sensitivity or soft-tissue irritation develops. A dental examination can identify decay, gum inflammation, exposed root surfaces, cracks, or mismatched restorations before whitening.

When should you avoid whitening strips and see a dentist?

Seek dental care before using whitening strips if you have tooth pain, untreated cavities, bleeding gums, ulcers, or a cracked tooth. Persistent sensitivity or a white or burned-looking gum after use needs assessment.

What should you ask about stains and existing restorations?

Ask what the active peroxide ingredient is, whether your stains are likely to respond, and how existing fillings or crowns will look after natural teeth change shade.
