Even with great oral hygiene, many people wish their smile was brighter and whiter. This is why teeth whitening is the most popular kind of cosmetic dentistry. With teeth whitening, it’s easy to maintain a bright smile throughout your life. Despite various online claims, hydrogen peroxide is the only chemical that can change the color of your smile to enhance its appearance. There are various ways in which a dental professional can whiten and brighten your teeth, such as sanding down stains, ultraviolet (UV) light therapy, and bleaching. The type of teeth whitening that’s right for you depends on the type and severity of the staining on your teeth. For example, some approaches are better for those with extrinsic staining, while others are better suited to people with both surface and internal darkening. By seeing a professional, you can find out which approach is recommended for you.
