Overview

CDT Code D9942 pertains to the repair and/or reline of an occlusal guard, a dental device used to protect teeth from grinding or clenching, often during sleep. This procedure involves either repairing a damaged guard or relining it to ensure a proper fit, which is crucial for the device's effectiveness. Dental professionals may perform this service when a patient's occlusal guard shows signs of wear, damage, or no longer fits correctly due to changes in the patient's dental structure. The procedure ensures that the occlusal guard continues to provide adequate protection and comfort.
