Can Mewing Reshape Your Face?

Though many YouTube and TikTok videos praise the practice, there’s not much evidence that mewing works. Mewing is a face-reconstructing technique that involves keeping your tongue on the roof of your mouth to change your jawline’s shape.1

Some supporters have claimed that mewing can reshape your face for a more defined jawline, helping with jaw pain, breathing, or orthodontic issues. On the contrary, experts have warned that people with jaw issues needing surgery or orthodontic work shouldn’t try mewing at Can Mewing Reshape Your Face?

Where Does Mewing Come From? 

Mewing isn’t a medical term. It was named after the British orthodontist Dr. John Mew, who popularized the method in the 1970s as part of his alternative orthodontic practice, orthotropics.1

Orthotropics uses facial and oral posture exercises and some appliances to change the jawline and face shape.2 It was initially intended for children to help influence jaw development and straighten teeth for a more aesthetic look. However, the London School of Facial Orthortopics, an organization founded and supported by John Mew, now also promotes the practice for adults. at Can Mewing Reshape Your Face?

The Mews argued that rather than the generally acknowledged hereditary link, human jaw size is decreasing due to environmental and lifestyle variables, such as eating soft food and breathing through the mouth. Smaller jaws may crowd teeth and alter the structure of the face, according to their theory. Mewing is said to assist solve this problem by strengthening and expanding the jaw, realigning teeth, and resulting in a more square-shaped jawline.4

How To Mew

The basics of mewing, according to the London School of Facial Orthotropics, involves keeping your mouth closed with:2

• The tongue touching the roof of the mouth
• The lips pressed together
• The top and bottom teeth touching or nearly touching

You’ll have to train yourself to naturally return to this position, which can take time and practice—potentially 14 months to 2 years.5 The gist of the mewing ideology is that continuously returning to this posture can help straighten teeth and improve facial structure at Can Mewing Reshape Your Face?

Does Mewing Work? 

Mewing has not been shown to permanently change the shape of your jaw in any reliable study. Mewing does not appear to be effective in treating conditions such as sinusitis, apnea, temporomandibular joint dysfunction (TMJ), or breathing difficulties.

Most of the claims come from John and Mike Mew or the Mews-backed London School of Facial Orthotropics. Promising before and after mewing pictures posted online are also unreliable since photo angling and lighting can be deceiving. At most, you might get a temporary contoured look if you try mewing during a photo session at Can Mewing Reshape Your Face?

Research has supported the observation that human jaws are getting smaller, which aligns with John Mew’s theory. In addition, oral posture, or how you position your teeth and tongue, has been shown to affect jaw development in children.6 A small study of 50 children even found that those who breathed through their mouths had minor changes to their facial features.7

Tongue alignment can change your facial structure. How you naturally rest your tongue can also clue in orthodontists on potential mouth issues, such as tongue thrusting that pushes teeth forward and causes bite, speech, or swallowing problems at Can Mewing Reshape Your Face?

Potential Risks

While it’s unlikely mewing will successfully change your jawline or teeth, trying to alter your jaw structure without healthcare provider guidance can be risky. Mewing shouldn’t be used to try to change your teeth or jawline. Instead, see a healthcare provider if you’re concerned about jaw structure issues.8 They can properly evaluate the complexities of your facial structure and determine a treatment plan.

Facial restructuring is quite complex and involves altering the jaw, facial bones, and soft tissue. Altering your jawline without expert guidance could cause lasting damage to these intertwined parts.8 However, since there’s not enough evidence to prove mewing works, the practice will unlikely cause any unwanted side effects. at Can Mewing Reshape Your Face?

Treatment Alternatives to Mewing

If your jaw shape, pain, or dental woes stem from a misaligned jaw—called malocclusion—you’ll likely need to see an orthodontist. Depending on the cause of a misaligned jaw, treatments may include:9

• Surgery: Corrective jaw surgery to help realign the upper and lower jaws
• Tooth repair:Reshaping or capping irregular teeth that cause overcrowding
• Orthodontics: Including braces, or metal bands attached to bonds on the teeth to help adjust tooth alignment at Can Mewing Reshape Your Face?
• Tooth removal: Removing teeth that cause overcrowding

If you want to change your facial composition or jawline for aesthetic reasons, cosmetic surgery and treatments are other potential options. However, these cosmetic procedures can be very pricey and come with their own set of risks. Some methods that can alter your jawline include:

• Facial contouring: Facial sculpting surgery that changes your chin, cheeks, and jawline’s shape by removing fat or adding implants10
• Dermal fillers (jawline contour treatment):Gel injected into the skin around the jaw to sharpen or adjust the symmetry of the jawline11
• Radiofrequency (RF) therapy:Energy waves are shot deep into your skin and create heat, which can stimulate collagen production or reduce fat to contour the facial skin12
