What is Mewing and is it bad for your teeth?

Mewing, introduced by Dr. John Mew, is a practice that involves specific tongue positioning, believed by some to reshape the facial structure, notably the jawline, enhancing aesthetic appeal. Despite its popularity on social media, dental professionals have raised concerns about its potential risks to oral health. Highlighting these concerns, experts from RJ Orthodontics in Austin, TX offer insights into the dental health hazards associated with mewing, underscoring the need for awareness and caution.

Teeth Misalignment Concerns

A key issue is the potential misalignment of teeth. Mewing requires the tongue to press against the roof of the mouth, which, if performed incorrectly, could exert uneven pressure on teeth. Over time, this might lead to shifts in teeth positioning, causing misalignment and bite problems. Such alterations not only impact the visual appeal of one’s smile but may also complicate chewing and cause uneven wear on teeth, potentially leading to more complex dental issues.

Potential for TMJ Disorders

The practice of mewing might also predispose individuals to Temporomandibular Joint (TMJ) disorders. These disorders affect the jaw joint and the muscles that facilitate jaw movement, manifesting as pain, difficulty in jaw movement, and a clicking noise when opening or closing the mouth. TMJ disorders can significantly affect an individual’s quality of life and often require professional intervention for management.

Risks of Gum Recession and Periodontal Diseases

Gum recession and periodontal diseases are additional risks associated with mewing. Incorrect tongue posture can apply unnecessary pressure on the gums, leading to recession, which exposes more of the tooth or the tooth’s root. This can increase sensitivity, heighten the risk of decay, and create a favorable environment for bacteria, leading to more severe gum diseases.

The Threat to Enamel Integrity

Enamel erosion is another concern linked to the constant pressure and friction from the tongue against the teeth during mewing. Since enamel, the tooth’s outer protective layer, does not regenerate once it’s worn away, teeth become more vulnerable to decay, cavities, and increased sensitivity. Maintaining enamel integrity is crucial for oral health.

The Importance of Professional Guidance

Considering these potential risks, approaching mewing with caution and seeking professional advice is crucial. Dental professionals at RJ Orthodontics are equipped with the necessary expertise to provide guidance and treatment plans tailored to individual dental health needs. They emphasize the importance of an informed approach to any oral health practice, ensuring individuals do not compromise their dental well-being.


While the concept of mewing offers an attractive prospect for those seeking non-invasive facial enhancements, understanding its potential dental health impacts is critical. Issues such as teeth misalignment, TMJ disorders, gum recession, and enamel erosion present serious concerns that warrant attention. Consulting with orthodontics experts like those at RJ Orthodontics ensures that individuals are making informed decisions regarding their oral health practices, prioritizing their dental and overall well-being in the process.
