3D professional crest whitening strips
Whitening strips use a peroxide gel on the tooth surface; results and irritation depend on the product and your dental health.
The short answer
Crest 3D whitening strips are flexible plastic strips coated with a peroxide whitening gel that contacts the enamel for a specified wear time. The gel can lighten some surface and internal tooth stains, but it cannot whiten fillings, crowns, veneers, or dentures.
What is the direct answer?
What does this question mean?
The active peroxide breaks down stain molecules within the tooth’s enamel and dentin. Sensitivity or gum irritation can occur when peroxide reaches exposed dentin, a crack, an ill-fitting strip edge, or inflamed gingiva.
What can you do next?
Read the package directions, fit the strip to the tooth surfaces, and keep gel off the gum margin. Do not extend wear time or combine products without professional guidance, and stop if pain or marked gum whitening develops.
When should you seek dental care?
Have a dental examination before whitening if you have untreated decay, cracked teeth, gum recession, ulcers, or strong sensitivity. Seek care for persistent pain, a lesion that does not heal, or uneven color that may reflect a restoration rather than stain.
What should you ask the dentist?
Ask whether the discoloration is surface stain, internal discoloration, decay, or a restoration, and whether whitening can change it. Ask how to protect exposed roots and what treatment will match any visible crowns or fillings.
Frequently asked questions
Can strips whiten yellow fillings?
No. They act on natural tooth structure, so a visible filling may remain a different shade.
Should sensitive teeth use whitening strips?
Sensitivity should be assessed first because exposed dentin, decay, cracks, or gum recession can worsen with peroxide contact.
