The short answer
Whitening strips sold under a product range such as Crest Luxe use peroxide gel to lighten natural teeth, with results and irritation depending on the formulation and your teeth.
How do Crest Luxe whitening strips lighten teeth?
A whitening strip is a thin plastic carrier that holds bleaching gel against enamel for a defined wear period. It is intended for natural teeth and cannot recolour tooth-coloured restorations.
Why might these strips cause sensitivity or irritation?
Sensitivity can occur when peroxide reaches dentine through microscopic pathways or when gel contacts the gums. Existing cavities, gum recession, enamel defects, cracks, and heavily stained restorations can change the result and the level of irritation.
Peroxide whitening strips can lighten natural enamel but do not change the shade of dental restorations.
What can I do before deciding on whitening?
Read the active ingredient and wear instructions, keep the gel away from the gum margin, and stop when sensitivity or burning develops. A dental cleaning can remove plaque and some external stain before a whitening decision.
Keep a record of changes and bring the product, appliance, or medication list to the appointment so the clinician can assess the relevant details.
When should a reaction to whitening be examined?
Have a dentist assess pain, a single dark tooth, gum recession, cavities, cracks, or a reaction that persists after stopping. Urgent care is appropriate for swelling, severe pain, or facial symptoms.
Do not delay assessment when symptoms are escalating, recurring, or affecting eating, sleep, mouth opening, breathing, or swallowing.
Is this product suitable for my teeth and restorations?
Ask whether the product is appropriate for your enamel, what will happen to existing restorations, and whether a cavity or gum problem should be treated before whitening.
Ask what the examination found, which treatment is intended to address the cause, and how you will know whether the problem is improving.
Frequently asked questions
Why did my gums turn white?
Temporary gum blanching can occur when peroxide gel contacts the tissue; remove the strip, rinse, and seek advice if the area remains painful or damaged.
What if the symptom keeps returning?
Arrange an examination because recurrent symptoms can need treatment of an underlying tooth, gum, appliance, or jaw problem.
