Internal Bleaching Per Tooth - CDT Code Guide
Overview
CDT Code D9974 refers to the procedure of internal bleaching per tooth, which is a cosmetic dental treatment aimed at improving the appearance of teeth that have become discolored due to intrinsic factors. This procedure involves the application of a bleaching agent inside the tooth, typically following a root canal treatment, to lighten the tooth from the inside out. It is particularly useful in cases where external bleaching methods are ineffective. Dental professionals often recommend this procedure for teeth that have darkened due to trauma, decay, or previous dental work. The process usually requires multiple visits to achieve the desired shade and is considered an adjunctive service to enhance the overall aesthetics of a patient's smile.
