The L shaped tongue depressor is composed of high-quality metal. It is used to depress the tongue, making it easier for the doctor to inspect the mouth and throat. It's a tongue depressor in the shape of an L, sometimes known as a tongue spatula.

A Lack's tongue depressor is used to hold down the tongue during medical examinations of the mouth and throat, particularly in general practice and otolaryngology (ENT specialty). Its L-shape allows for better visibility of the oral cavity and pharynx, facilitating procedures like taking throat cultures, assessing oral health, and conducting surgical biopsies. These tools are often made of stainless steel, have smooth edges for patient comfort, and are available in adult and child sizes.
