Colgate optic white professional take home kit

Peroxide passes into enamel and dentine and breaks down coloured molecules, so the natural tooth structure can become lighter. Crowns, veneers, fillings, and bonding do not bleach in the same way, and whitening does not treat decay or a dark tooth caused by pulp disease.

Read the product directions and use only the supplied amount and schedule; do not leave gel on longer or add extra applications. Keep gel off the gums, pause if strong sensitivity develops, and have a dentist check untreated decay, leaks, cracks, or gum inflammation before continuing.

Seek dental advice for sharp or lingering sensitivity, gum burning, uneven colour, or pain in one dark tooth. Get an examination before use if you have active cavities, gum disease, enamel defects, extensive restorations, or a history of difficult sensitivity.

Ask which formulation and wear time match your teeth, whether the tray fits without gel touching the gums, and how existing restorations will look afterward. Ask how to manage sensitivity and what alternative treatment fits stains that peroxide cannot change.
