Dental whitestrips
Whitening strips use peroxide gel to lighten stains on natural enamel, but not fillings, crowns, or veneers.
The short answer
Whitening strips are thin plastic trays coated with a peroxide gel that lightens some stains on natural tooth enamel.
What is the direct answer?
What does this question mean?
Sensitivity or gum irritation can occur when peroxide reaches exposed dentine or rests against the gingiva, so fit and wear instructions matter.
What can you do next?
Use only as directed, keep the gel off the gums, and stop if marked pain, ulceration, or persistent sensitivity develops.
When should you seek dental care?
A dental examination is appropriate before whitening when there is decay, gum disease, enamel loss, pregnancy, or extensive tooth-coloured restoration.
What should you ask the dentist?
Ask whether the darkening is an external stain or an intrinsic colour change, whether your restorations will match, and which concentration and wear time suit your teeth.
