How long does enlighten teeth whitening last

Enlighten whitening commonly remains noticeable for several years, but diet, smoking, enamel staining and maintenance affect its duration.

Enlighten is a professional tooth-whitening system that uses peroxide gel to oxidise stain molecules within enamel and dentine. It changes the colour of natural teeth, not crowns, fillings or veneers.

Have the dentist examine decay, cracks, gum inflammation and existing restorations before whitening. After treatment, brush with fluoride toothpaste, clean between teeth, limit frequent dark or acidic drinks, and follow the prescribed maintenance trays and gel rather than improvising with stronger products.

Arrange an examination if whitening causes persistent sensitivity, gum burning, uneven colour, or pain in one tooth. A dentist should also assess a dark single tooth because its colour may come from pulp injury rather than surface stain.

Ask whether your discolouration is intrinsic or surface staining, which restorations will not change colour, how the trays and gel should be maintained, and what sensitivity plan is appropriate for your teeth.
