Dr. Michael Kosdon discusses the differences between in-office teeth whitening treatments and over-the-counter whitening solutions.

New York, NY – It’s been said that a person’s smile can make the difference between a good first impression and a bad one – and many people are taking advantage of cosmetic dentistry procedures designed to give them whiter, healthier-looking teeth. Teeth whitening is one of the most popular procedures at the practice of Michael Kosdon, DDS, a cosmetic dentist in Manhattan who also has an office in Beverly Hills. While there are many teeth whitening treatments that can be purchased over-the-counter, Dr. Kosdon says it’s important for people to know the differences between a professional, in-office whitening treatment and those you can get at a supermarket or drugstore.

Discoloration, stains, and yellowing of the teeth are caused by a number of factors, including the natural aging process, the use of tobacco products, and long-time consumption of beverages such as coffee and wine. A professional teeth whitening treatment can lighten the teeth by several shades with the application of an advanced bleaching agent. Once the solution is placed along the teeth, a special light is used to activate it, which then oxygenates the teeth and makes them appear whiter. Dr. Kosdon says, while certain over-the-counter teeth whitening treatments can offer somewhat effective results, many of those options use a lower level of bleaching solution than an in-office treatment, leading to results that may be less noticeable. He also notes that optimal effects from over-the-counter treatments often take a while to become apparent, whereas in-office procedures typically offer near-instantaneous results. In addition, Dr. Kosdon says professional treatments are able to provide protection to the gums from the bleaching effects of the solution, and they are supervised by dentists who know how to customize the treatment for the best possible outcome.

Dr. Kosdon says even at-home whitening treatment options available at his practice can be preferable to over-the-counter solutions. He notes that his at-home kits offer custom-designed whitening trays based on an impression taken from the patient’s teeth, rather than the one-size-fits-all approach employed by over-the-counter whitening treatments.

Ultimately, Dr. Kosdon says, professional teeth whitening can serve as an investment in an individual’s smile, offering results that last longer than other other types of whitening treatments. He says in-office teeth whitening procedures give patients the opportunity to significantly whiten their teeth and feel more confident during that all-important first impression.
