Dental mirrors are small, handheld tools used by dentists and dental hygienists to help examine a patient's mouth. They have a reflective surface that allows professionals to see areas that are difficult to view directly, such as the back of the teeth and gums. This helps in identifying issues like cavities or gum disease. These mirrors come in various shapes and sizes, often with a long handle for easy maneuverability. They are typically made of stainless steel or plastic and are designed to be sterilized for hygiene. Using a dental mirror is a standard practice in dentistry to ensure thorough oral examinations.
