Dental mirrors are a mainstay of just about any operatory. Usually handheld, dental mirrors allow dentists and hygienists to see different areas of the mouth and examine a patient's teeth and gums from a variety of angles. These mirrors should be small enough to maneuver within the patient's mouth and comfortable in the clinician's hand. Mirrors can be disposable or reusable. Fog-resistant mirrors can be useful as well. Whether you choose to go with single-use disposable mirrors or mirrors designed for sterilization, it is important to keep a supply of dental mirrors ready throughout the day.
