Colgate optic white professional take home kit
A professional take-home whitening kit uses peroxide gel in trays or strips, with results and irritation depending on the product and your teeth.
The short answer
The Colgate Optic White Professional take-home kit is a tooth-whitening system that uses peroxide gel delivered through a prescribed or supplied tray or strip. Whether it is suitable depends on cavities, gum health, restorations, sensitivity, the exact formulation, and how the product is used.

Why does peroxide make natural tooth structure look lighter?
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.
How should you follow the kit schedule and gel instructions?
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.
When should you stop whitening and contact a dentist?
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.
What should you ask about fit, wear time, and restorations?
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.
Frequently asked questions
Can I use the kit with fillings?
A dentist should check the fillings and the surrounding tooth first because whitening can make natural tooth colour differ from restorations.
What if the gel touches my gums?
Wipe it away, rinse, and stop if burning or soreness continues; the tray or schedule may need adjustment.
