Tooth whitening is a cosmetic dental procedure designed to lighten the color of teeth and reduce stains or discoloration. Stains can be caused by foods, drinks, tobacco use, aging, or certain medications. Whitening treatments work by using bleaching agents that break down stains on the enamel, resulting in a brighter and more uniform smile.

There are several tooth whitening options available, including professional in-office treatments and dentist-prescribed at-home kits. Professional whitening is closely supervised to ensure safety and effective results, while at-home treatments provide gradual improvement over time. When done correctly, tooth whitening can significantly enhance a person’s smile and boost confidence without damaging the teeth.
