Bleaching is the simplest way to brighten your smile. Discoloration caused by food and lifestyle habits can be lightened to reveal a glowing smile. The bleaching solution is applied to the teeth and activated with a special light in the dental clinic. Alternatively, a bleaching gel is provided to you to be used with a custom made tray at home. Your teeth can become 5-6 shades lighter. Depending on your lifestyle, you may need to bleach periodically.
