Tooth Bleaching and Whitening is a simple, non-invasive dental treatment which is used to change the color of natural tooth enamel to enhance the aesthetic look of teeth. In-office bleaching is a chemical or laser treatment for your natural teeth that uses peroxide to produce the whitening effect. There are many types of bleaching options available, including at-home whitening kits and in-office options. To find the best option for you, please visit with your dentist. This is not a permanent procedure and may need touch-ups especially if you drink coffee, tea, or are a smoker.
