Is Crest whitening safe for your teeth and gums?
Peroxide whitening strips may irritate gums or cause sensitivity, depending on the product, teeth, and application.
Whitening strips place a peroxide-containing film against the front surfaces of the teeth. Sensitivity can occur when peroxide reaches dentine through enamel or exposed root surfaces, while a strip that overlaps the gums can irritate soft tissue; crowns, fillings, and veneers will not change colour.
How should you use peroxide whitening strips safely?
Read the product directions, keep the strip on only for the stated time, and avoid placing it over broken skin or irritated gums. A dental examination is sensible before use if you have untreated decay, leaking restorations, recession, cracks, or a history of pronounced sensitivity.
What should you do if whitening causes irritation?
Stop using the strips and seek dental advice for severe pain, swelling, blistering, a persistent white gum patch, or sensitivity that does not settle. Urgent care is needed for facial swelling, difficulty swallowing, or breathing.
When should a dentist assess whitening symptoms?
Ask the dentist whether the product fits your teeth and restorations, whether exposed roots or cavities need treatment first, and how to respond to sensitivity. Confirm what result is realistic if visible restorations are present.
What should you ask about strips and tooth sensitivity?
Peroxide products can affect natural tooth tissues and the gingiva if misapplied.
