Tongue depressors are flat, thin tools typically made of wood or metal, used primarily in medical examinations to hold down the patient's tongue. This allows healthcare providers a clear view of the throat, mouth, and tonsils. They are commonly used in ENT (ear, nose, and throat) practices, general check-ups, and oral procedures. Wooden tongue depressors are disposable, hygienic, and ideal for single use, while metal versions are reusable after sterilization. They are essential instruments in both diagnostic and minor clinical procedures for safe and effective examination of the oral cavity.
