How long do crest 3d white strips last

Crest 3D Whitestrips lighten removable surface and internal tooth stains for a limited period, so the result gradually fades as new stains build.

Whitening strips are flexible plastic strips coated with a peroxide-based whitening gel.

The peroxide oxidizes stain molecules in enamel and dentin; it does not change the color of fillings, crowns, veneers, or other restorations.

Use the product only as its label directs, keep it off the gums, and reduce staining drinks and tobacco exposure after whitening.

See a dentist before whitening if you have cavities, gum disease, cracks, exposed roots, or strong sensitivity.
