What are Crest 3D Whitestrips made to do?
Crest 3D Whitestrips are adhesive strips containing a peroxide whitening gel that contacts the front surfaces of natural teeth.
How does peroxide affect tooth colour?
The peroxide breaks down some color molecules in enamel and dentin during the instructed wear period. Strips cannot whiten fillings, crowns, veneers, or other restorations, and may not correct every intrinsic stain or an isolated dark tooth.
How can you use strips on suitable teeth?
Read the directions, keep gel off the gums, and use strips only on suitable natural teeth. Stop for gum irritation or strong sensitivity, and have pain, cavities, recession, or restorations assessed before continuing.
Which whitening changes should a dentist assess?
Ask a dentist about persistent sensitivity, gum soreness, uneven color, or a tooth that remains dark. Evaluation is appropriate before whitening with untreated cavities, cracks, gum disease, or exposed roots.
What should you ask about the affected tooth material?
Ask which structure or material is involved, what findings support the diagnosis, and which treatment addresses the cause. Ask what to do today and which changes require urgent review.
Frequently asked questions
Can this be managed at home?
Simple measures may reduce irritation or discomfort, but persistent, severe, or recurring symptoms need an examination.
What should I tell the dentist?
Share when it began, where it occurs, what triggers it, recent dental work, medicines, and any visible change.
