There are many products and techniques available for patients who want to achieve a brighter smile, and with so many options available, it can be difficult to choose the method that is right for you. The best way to begin any teeth-whitening regimen is to schedule an appointment and talk to us about the differences between at-home whitening and the in-office professional whitening.The at-home whitening uses special trays and a whitening gel. The whitening gel is placed in trays that fit over your teeth. As the peroxide in the gel breaks down, hydroxyradicals help whiten stained teeth. The in-office professional whitening uses a light activated whitening gel to whiten the teeth at the dental office. The results of this are noticable immediately.
