What is the purpose of a tongue blade or depressor?

The primary purpose of a tongue blade or depressor is to depress the tongue during throat examinations. This allows healthcare professionals to gain a clear view of the throat, tonsils, and other surrounding structures. By holding the tongue down, the depressor creates space in the mouth, making it easier to inspect for any irregularities or signs of infection. This tool is commonly used in clinical settings to facilitate thorough examinations without causing discomfort to the patient.

The focus is on providing a clear line of sight into the back of the throat, which is crucial for identifying issues such as inflammation, lesions, or obstructions. The other potential uses, while related to oral care or examination, do not align as closely with the primary use of a tongue depressor.
