## Abstract

An adjustable mouth shield device provides an adjustably fitted mouth shield with adjustable headband for secure fit. An adjustable headband is fastened to a padded earpiece. A straight first extension from the earpiece is angled downwardly and forwardly to terminate in a swivel joint providing almost 360 degrees of swivel. A second extension is arced both downwardly and forwardly. A mouthpiece is fitted to an adjustable spring mount for horizontal pivot of the mouthpiece. The mouthpiece may, by virtue of the swivel joint and the spring mount, be moved completely away from a user's mouth and, in turn, pivoted and swiveled to be directly in front of the user's mouth. A filter is releasably attachable to the mouthpiece to shield a user's breath from objects, foods and other materials.
