In office-tooth whitening is a safe, quick way to transform the appearance of discolored or yellowing teeth into a noticeably brighter smile. Many reasons contribute to dull looking teeth, wine, coffee, cola, smoking, or even the normal effects of aging. But there is a way to transform the brightness of your teeth to help you regain an aesthetically pleasing smile. The procedure starts with some brief prep to cover the lips and gums exposing only the teeth. A hydrogen peroxide gel is applied that penetrates the tooth's dentin and enamel bleaching any discolored spots while leaving the tooth structure unchanged. A special lamp light is used to help speed up the procedure and break down the hydrogen peroxide so the oxygen can begin its bleaching work. Once the whitening process is completed, a special gel paste is applied to further reduce any sensitivity you might experience. Your doctor will also provide clear trays for touchup at home treatments. Be sure to follow your doctor's instructions on how to use these in office. Whitening is a simple, effective way to brighten your teeth and instantly feel refreshed and less self-conscious about your smile.
