Tooth whitening is a simple, non-invasive procedure that removes stains and brightens teeth. It can be done using professional in-office treatments or at-home whitening kits. In a clinic setting, a protective gel is applied to the gums, followed by a whitening agent (hydrogen or carbamide peroxide) on the teeth. A LED or laser light may be used to enhance results. The process takes 30–60 minutes and provides instant brightness. At-home kits include custom trays with whitening gel for gradual results. Safe and effective, it restores a radiant, stain-free smile effortlessly
