Can you sculpt your jawline with your tongue? The internet is buzzing about "mewing," but does this tongue posture trick really work? Dr Rachel Hall, Brisbane holistic dentist exposes the facts behind mewing, its limitations and potential risks. Mewing is a popularized technique that involves placing your tongue in a specific position in your mouth to supposedly change your jawline and facial structure. It's named after a British orthodontist, Mike Mew, who promotes a theory of facial development called orthotropics. Here's the gist of mewing: The Technique: Mewing involves resting your tongue flat against the roof of your mouth, including the back of your tongue. Basically, your tongue posture is supposed to train your jaw muscles and influence the shape of your jawbone. The Claims: Proponents of mewing claim it can lead to a more defined jawline, improved facial aesthetics, and even better breathing and sleep. Some even go further suggesting benefits for jaw pain, speech disorders, and sinusitis.   www.evolvedental.com.au www.holisticdentistry.au
