Crest whitestrip supreme
Crest Whitestrips Supreme are peroxide whitening strips placed on the front teeth; use them only as directed and stop if irritation develops.
The short answer
Crest Whitestrips Supreme are flexible strips coated with a peroxide-based whitening gel. They are placed against the front tooth surfaces for the time stated on the package, and they can cause temporary sensitivity or gum irritation.

What is the direct answer?
What does this question mean?
The gel contacts enamel and breaks down some stain molecules within the tooth surface. It does not whiten fillings, crowns, veneers, or other tooth-coloured restorations, so those may not match after natural teeth lighten.
What can you do next?
Check the package directions, apply the strips to clean, dry teeth without covering the gums, and remove them after the stated wear time. Do not cut, sleep in, or repeatedly extend the treatment without dental advice.
When should you seek dental care?
Arrange a dental examination before whitening if you have untreated decay, cracked teeth, gum disease, exposed roots, or extensive restorations. Stop use and seek advice for severe pain, persistent burning, or marked gum whitening.
What should you ask the dentist?
Ask whether the shade change is suitable for your enamel and restorations, whether sensitivity risk is increased by exposed dentine, and which whitening method fits your mouth.
Frequently asked questions
Will the strips whiten fillings?
No. They can lighten natural teeth but do not change the colour of fillings or crowns.
What if the gel touches my gums?
Remove the strip, rinse, and allow the tissue to settle; persistent burning or ulceration warrants dental advice.
