Adjunctive General Services/Drugs

Overview

CDT code D9972 refers to the procedure of external bleaching per arch performed in a dental office. This cosmetic dental procedure is designed to lighten the color of teeth by applying a bleaching agent to the external surfaces. Typically, this procedure is sought by patients who desire a brighter smile and is performed under the supervision of a dental professional to ensure safety and effectiveness. The procedure involves isolating the teeth, applying a bleaching gel, and sometimes using a special light to enhance the whitening effect. It is commonly used for patients with extrinsic stains caused by food, drink, or smoking.

For patients with extrinsic stains from coffee, tea, or tobacco.
