Colgate optic white home kit
A Colgate Optic White home kit uses peroxide to lighten some stains, but results vary and restorations do not whiten.
The short answer
The kit is an at-home tooth-whitening system. Follow the exact product instructions for preparation, application time, frequency, storage, and disposal because formulations and applicators differ between kits.
How does peroxide work on stains in enamel and dentin?
Peroxide breaks down some organic stain molecules in enamel and dentin. It does not change the colour of crowns, fillings, veneers, or other dental restorations.
How can you use the whitening kit more safely at home?
Check the teeth and gums first, keep gel off the gum margin, use only the supplied amount, and stop if marked sensitivity or gum irritation develops. Treat cavities, cracks, leaking fillings, or active gum inflammation before whitening.
When should a dentist check your teeth before whitening?
Ask a dentist before use if you are pregnant, have untreated dental disease, severe sensitivity, enamel defects, or extensive restorations. Seek care for persistent pain, ulceration, or swelling.
What should you ask about stains, restorations, and sensitivity?
Ask whether the discoloration is a surface stain or internal change, which restorations will remain unchanged, and whether whitening may irritate your gums or sensitive teeth.
Frequently asked questions
Can the kit whiten a crown?
No. Whitening changes natural tooth structure, while a crown’s shade remains the same.
What if my gums turn white?
Remove the product and rinse; persistent irritation or pain warrants dental advice.
