Colgate optic white professional teeth whitening kit

A peroxide whitening kit can lighten some tooth stains, but its suitability depends on enamel, fillings, gum health, and product instructions.

Optic White is a consumer whitening range rather than one single clinical procedure. Whitening agents diffuse through enamel and dentine to alter some internal stain molecules, while crowns, veneers, fillings, and bonding do not change color in the same way.

Check the exact kit, active ingredient, concentration, tray design, expiry date, and directions before use. Treat cavities, cracked teeth, gum inflammation, or exposed roots first, and stop if marked sensitivity or gum irritation develops.

Ask for a dental examination before whitening when you have pain, untreated decay, gum bleeding, enamel defects, restorations on visible teeth, or a single dark tooth. A dentist can identify the stain and choose whitening, restorative treatment, or another option.

Ask which stains are likely to respond, whether your teeth and gums are ready, and how existing restorations will look afterward. Ask about tray fit, sensitivity control, and alternatives if the shade difference is caused by a crown or veneer.
