Cosmetic
Whitening
Tooth whitening is a cosmetic procedure that uses peroxide-based bleaching agents to lighten the colour of natural teeth, available as in-office, take-home, or over-the-counter treatments.
Professional in-office systems such as Philips Zoom and KoR deliver the most predictable results. At-home options include strips and trays — see our pick of the best OTC whitening strips and our dentist-approved whitening guide. After treatment, follow our advice on what to eat afterwards.
