How do whitening strips break down tooth stains?

The gel diffuses through enamel and dentine to break down some stain molecules. It does not whiten fillings, crowns, veneers, or other dental restorations, so existing restorations may not match afterward.

How should you apply whitening strips safely?

Read and follow the product directions, keep gel off the gums, and stop if marked pain or a chemical burn develops. Do not use strips over untreated decay, cracked teeth, active gum inflammation, or unexplained sensitivity without a dental assessment.

When should whitening-strip symptoms be checked by a dentist?

Arrange care for severe or lasting sensitivity, white or peeling gum patches, pain from a specific tooth, or uneven colour. A dentist should check decay and restorations before whitening.

What should you ask before choosing whitening strips?

Ask whether the stains are intrinsic or surface stains, whether existing restorations will need replacement for colour matching, and which whitening method fits your enamel and gums.

Frequently asked questions

When should this be checked?

Arrange care for severe or lasting sensitivity, white or peeling gum patches, pain from a specific tooth, or uneven colour. A dentist should check decay and restorations before whitening.
