Teeth whitening is a cosmetic dental treatment designed to lighten and brighten discolored or stained teeth. Using professional bleaching agents, dentists remove deep stains caused by food, beverages, smoking, or aging. The procedure is safe, effective, and can dramatically enhance your smile’s appearance. Regular maintenance and good oral hygiene help preserve results, while professional whitening ensures even, long-lasting effects that over-the-counter products often cannot achieve, boosting both confidence and aesthetics.
