How does the strip hold whitening gel on your teeth?

The strip holds gel against front tooth surfaces. Peroxide can break down some stains, while fillings, crowns, and veneers generally keep their original colour.

How should you prepare before using whitening strips?

Follow the label, keep gel off the gums, and treat cavities, inflamed gums, exposed dentine, and leaking restorations before whitening.

When should uneven whitening or sensitivity be assessed?

Arrange assessment for persistent sensitivity, gum injury, uneven whitening, or a dark single tooth.

What should you ask about the cause and options?

Ask what diagnosis, material, force, ingredient, or follow-up finding applies to my teeth and gums, and what alternatives should be considered.
