What is the primary function of the mouth mirror?

The primary function of the mouth mirror is to illuminate the oral cavity. It serves as an essential tool in dental practice, allowing practitioners to view areas of the mouth that are difficult to see directly. The reflective surface of the mirror helps provide a clear view of the teeth and gingiva, improving the clinician's ability to diagnose conditions and perform procedures effectively.

While the mouth mirror can aid in tissue retraction, its primary purpose is to enhance visibility and lighting within the oral cavity. This function is critical during examinations and various procedures, as good visibility is necessary for accuracy and safety in dental work. Other functions of dental tools exist, but the connection of the mirror to illumination is what sets it apart as a fundamental device in patient care.
