Teeth whitening is a cosmetic dental procedure aimed at removing stains and discoloration from teeth. It addresses extrinsic stains caused by factors like food, beverages, and tobacco, as well as the natural discoloration that comes with aging. Besides enhancing aesthetics, teeth whitening boosts confidence and self-esteem, making it a popular choice before special occasions. The procedure is non-invasive, offering both professional in-office treatments and at-home options. While effective for most extrinsic stains, intrinsic discoloration may require alternative cosmetic solutions. Regular dental check-ups can guide individuals in choosing the most suitable teeth whitening approach based on their oral health.
