Over the years, Dental Bleaching has become one of the renowned aesthetic dental treatment. Initially, dentists preferred in-office bleaching of teeth which were discolored due to trauma of an endodontic treatment. However, later home-applied tray bleaching and similar products came into the market therefore making this technique more flexible in terms of its application both in the dental office or at home.
In-Office Tooth Whitening: In this procedure, a bleaching gel is applied by isolating the teeth from lips and gums. In order to accelerate the bleaching process, the dentists uses a special curing light along with the gel.
At-Home Tooth Whitening: In this process, the dentist will design a fully customized teeth whitening tray for your mouth. Once the trays are designed, you will be provided with the instructions of applying the bleaching agent at home.
Listed below are the commonly used ADA codes for Dental Bleaching:
D9972: This is for external bleaching (over the surface of the tooth) per arch and is performed in the dental office under the supervision of your dentist to ensure accurate results.
