A new social media trend is making waves, claiming to improve your jawline and facial structure—this technique is known as “mewing.”
If you search for “mewing” on TikTok, you’ll find thousands of videos boasting millions of views, with people sharing their experiences and supposed results from trying out this method.
But what exactly is mewing, and does it actually work?
The Origins of Mewing: A Technique Rooted in Orthodontics
Mewing is named after two British orthodontists, John and Mike Mew, who developed it as part of their orthodontic practice called orthotropics.
This branch of dentistry focuses on treating misaligned bites by correcting oral and head posture. John Mew began using this technique on his own children, particularly his daughter, who had poor facial alignment and crooked teeth until the age of four.
The practice itself is simple in theory: it involves placing your tongue against the roof of your mouth and applying pressure to your upper gum. Over time, proponents claim, this can alter the structure of your jaw if done consistently.
Claimed Benefits: Can Mewing Really Enhance Your Jawline?
Advocates of mewing suggest that regular practice can lead to a more defined, square-shaped jawline.
Beyond cosmetic changes, some reports claim that mewing can improve sleep quality and reduce mouth breathing.
According to one scientific paper, the technique is even purported to help with conditions such as sleep apnea, breathing and swallowing issues, temporomandibular joint dysfunction (TMD), and sinusitis.
How to Practice Mewing: A Step-by-Step Guide
For those interested in trying mewing, the process is straightforward 👄⬆️
-Start by closing your mouth and resting your lower teeth just behind your upper front teeth
-Then, flatten your tongue against the roof of your mouth
-Keeping your lips sealed
-Hold this position for about 30 seconds and repeat the exercise several times throughout the day.
Expert Opinions: Does Mewing Really Work?
When it comes to the effectiveness of mewing, expert opinions are mixed. Dr. Chelsea Perry, DMD, from Elite Dental Studio, expressed skepticism:
“There is no scientific evidence to support it. The shape of your face really comes down to genetics, muscle development, and bone growth. Not only does mewing not work, but it can also cause problems.”
She warned that forcing your tongue into an unnatural position could disrupt tooth alignment and worsen bite issues or speech problems.
Dr. Matt Jones at Circ Dental echoed these concerns, noting that “the jawline’s structure is largely determined by the mandible (jawbone) and the overlaying muscles—not something easily changed by mere tongue placement.”
For those seeking significant facial changes, he recommended consulting healthcare professionals and considering options like orthognathic surgery, braces, or non-invasive treatments such as dermal fillers.
Exploring the Potential Health Benefits: A Closer Look
Some proponents of mewing also claim that it can improve overall health, particularly in areas like sleep apnea and sinusitis. James Cunningham, a fitness coach with a BSc in Sport & Exercise Science from the University of Hertfordshire, offered insights into these potential benefits.
He explained that “mewing enthusiasts believe that proper tongue posture can lead to a more defined jawline, improved facial symmetry, and even correction of malocclusion (misalignment of teeth).” While there is some anecdotal evidence to support these claims, scientific research remains limited.
Regarding health benefits, Cunningham noted that “the theory is that by expanding the airway through proper tongue posture, mewing might alleviate symptoms of sleep apnea by allowing for better airflow during sleep.”
Some individuals have reported improved sleep quality after practicing mewing, but more rigorous studies are needed to confirm these effects.
As for sinusitis, Cunningham acknowledged that “the connection to mewing is less straightforward.” While some suggest that proper tongue posture might improve nasal breathing and alleviate symptoms of sinusitis, the scientific evidence supporting this claim is also lacking.
Conclusion: Should You Try Mewing?
Mewing has captured the attention of many on social media, with claims of enhancing facial structure and improving health. However, experts caution that the technique lacks scientific backing and may even cause harm if practiced incorrectly. If you’re considering mewing for aesthetic or health reasons, it’s important to consult with a healthcare professional to explore safer and more effective options.
