Teeth whitening is a cosmetic dental procedure designed to lighten the color of a person’s teeth, making them appear whiter and brighter. It involves the use of bleaching agents, such as hydrogen peroxide or carbamide peroxide, to remove stains and discoloration caused by factors like aging, food and drink consumption, or smoking. Teeth whitening can be done professionally at a dentist’s office or using over-the-counter products at home, and it can help enhance a person’s smile by achieving a more attractive and youthful appearance for their teeth.
