Mewing, a term coined after Dr. John Mew, refers to a technique that involves proper tongue posture. Proponents of mewing claim it can help reshape the face by positioning the tongue against the roof of the mouth, thus potentially influencing the jawline and overall facial structure. Despite its popularity on social media platforms, there are concerns and hazards associated with mewing, particularly when it comes to dental health. This blog post explores the potential risks mewing poses to teeth and overall oral health.

Misalignment of Teeth

One of the significant hazards of improperly practiced mewing is the potential misalignment of teeth. The constant pressure applied by the tongue against the teeth can lead to unintended movement over time. This movement might not only affect the aesthetics of one’s smile but can also lead to bite issues. Misalignment can result in a host of problems, including difficulty in chewing and increased wear on certain teeth, leading to further dental complications.

Temporomandibular Joint (TMJ) Disorders

The temporomandibular joint connects the jaw to the skull, and strain in this area can lead to TMJ disorders. Mewing, especially when overdone or done incorrectly, can place undue stress on the TMJ, leading to pain, difficulty in moving the jaw, and even a clicking sound when opening or closing the mouth. TMJ disorders can be uncomfortable and might require medical or dental intervention to correct.

Gum Recession and Other Periodontal Issues

Proper tongue posture is crucial in maintaining oral health; however, excessive or incorrect pressure from mewing can harm the gums. This can lead to gum recession, where the gum tissue pulls back from the tooth, exposing more of the tooth or the tooth’s root. Exposed roots can lead to increased sensitivity and provide a breeding ground for bacteria, leading to periodontal diseases.

Enamel Wear

The constant pressure and rubbing of the tongue against the teeth can also lead to the wear of enamel over time. Enamel is the hard, outer layer of the tooth that protects it from decay. Once it wears down, it does not regenerate, leaving teeth vulnerable to cavities, decay, and increased sensitivity.

The Importance of Professional Guidance

While the idea of mewing and its potential benefits might seem appealing, it’s crucial to approach any practice that involves the alteration of facial structure or dental positioning with caution. Orthodontic treatments and interventions should always be supervised by professionals. Orthodontists undergo years of training to understand the complexities of facial growth, dental development, and the proper alignment of teeth and jaws.

For those considering mewing or experiencing issues believed to be related to mewing, consulting with a dental professional is essential. An orthodontist can provide guidance tailored to individual needs and conditions, ensuring that any practice aimed at improving oral posture or health does not inadvertently lead to dental harm.


While mewing has gained attention as a potential way to improve facial aesthetics, the hazards associated with improper practice, particularly concerning teeth and overall oral health, cannot be overlooked. It underscores the importance of seeking professional advice before embarking on any practice that could impact dental health. Ultimately, the safety and health of one’s teeth and gums should take precedence over unverified cosmetic practices.
