Colgate optic white gel professional whitening

Optic White gel is a peroxide-based tooth-whitening product; a dental professional should check the teeth and gums before choosing its use.

Whitening gel uses a peroxide compound that breaks down stain molecules within enamel and dentin, making teeth look lighter. The result depends on formulation, contact time, starting shade, and whether the colour is a surface stain or restoration.

Have a dentist examine cavities, cracks, gum recession, and existing fillings, crowns, or veneers before whitening. Follow the prescribed application time, keep gel off the gums, and stop if marked sensitivity or soft-tissue irritation develops.

Seek dental care before whitening when a tooth hurts, has a visible cavity, reacts sharply to cold, or has a dark single-tooth colour change. Contact the clinician for persistent sensitivity, gum burns, or swelling.

Will gel whiten fillings or crowns? No, peroxide changes natural tooth colour but does not change most tooth-coloured restorations. Why might whitening cause sensitivity? Peroxide can irritate exposed dentin or the pulp, especially when recession or defects are present.
