What is an over-the-counter peroxide whitening system?
The product is an over-the-counter tooth-whitening system made from flexible strips coated with a peroxide gel. The gel oxidizes some color molecules within enamel, while stains caused by decay or a restoration require a different dental solution.
How should you apply whitening strips to clean teeth?
Read the package directions, apply the strip to clean dry teeth for the stated contact time, and avoid letting gel sit on the gum margin. Stop if marked sensitivity or gum irritation develops, and have untreated cavities, cracked teeth, or leaking restorations examined before whitening.
When can one dark tooth indicate a dental problem?
See a dentist if discoloration is limited to one tooth, follows trauma, or comes with pain, because the pulp or enamel may be involved. Dental advice is also appropriate when sensitivity persists after stopping the strips or when existing restorations will make the shade uneven.
Can whitening match the colour of your restorations?
Ask whether the color change is an external stain, an enamel change, or an internal tooth problem, and whether whitening can match your restorations. Ask which peroxide concentration and contact time fit your enamel, gums, and history of sensitivity.
Frequently asked questions
Will strips whiten a crown?
No; a crown keeps its existing shade while nearby natural enamel may lighten.
Why do my teeth hurt after whitening?
Peroxide can temporarily reach sensitive dentine pathways; stop the product and seek advice if discomfort persists.
