Teeth whitening is a popular dental treatment method used to restore or lighten the natural color of teeth. This treatment aims to eliminate stains, discoloration, or color changes in the teeth. Teeth whitening can be carried out by applying whitening gels to the tooth surface or by interacting with a special light source. Whitening agents penetrate the tooth enamel, dissolve pigments, and give the teeth a whiter appearance. The teeth whitening procedure provides fast and effective results and is generally considered a safe process. However, the health of the teeth and the suitability of the whitening method should be taken into consideration. Evaluation and consultation by a dentist are important for a safe and successful teeth whitening experience. Regular dental care, maintaining good oral hygiene, and paying attention to dietary habits help ensure the long-lasting effects of whitening.
