The technique that promises a defined jawline is going viral on social media. Experts warn of risks – Executive Summary

On social media, beauty and health trends emerge and spread at an astonishing speed, and one of the latest is “meow.” This technique, which promises a defined and perfect jawline through specific tongue position, has gained millions of followers. However, this phenomenon has raised controversy and concerns among experts.

Gemma Díaz Gil, a professor of human anatomy and embryology at Rey Juan Carlos University in Spain, explains to The Conversation that “meowing” is nothing new. “The idea goes back to the 1970s with British orthodontist John Mew and the orthodontic technique he invented,” Gill explains.

This technique, which aims not only to align teeth but also to “enhance the face,” is based on the premise that mouth position can influence facial growth, improving jaw shape and tooth alignment.

“Meowing” and the promise of the perfect face

The “meow” suggests a specific position of the tongue: it is placed on the roof of the mouth behind the upper incisors, with the teeth and lips also closed. This technique has been popularized in viral videos, promising impressive results. “When practicing this routine, the 'meow' promises to define the jawline, giving it a sharper shape without the need for surgery or devices,” highlights Jill.

Moreover, many moonwalkers claim that this technique helps treat sleep apnea, sinusitis, snoring and jaw pain, although “there are no scientific foundations to support these claims,” the expert highlights.

The dangers of “meowing”

However, Gill warns that forcing the tongue position can backfire. “The tongue is a complex muscular organ designed to perform functions such as speaking, chewing and swallowing. Imposing your posture may have risks, such as changes in the temporomandibular joint or tooth displacement,” he warns.

Despite many of Meow's followers posting “before and after” photos and promoting the technique as a beauty treatment for adults, in 2019, Michael Mew, son of Jun Mew and promoter of “Meow”, was expelled from the British Orthodontic Association for providing inadequate treatments. And promoting alternatives that are not supported by scientific orthodontics.

As the phenomenon grows on social media, it is essential to be critical and cautious regarding these viral trends. “It is important to be decisive and careful regarding these viral fads. Health must always come first,” concludes Gemma Díaz Gil.

Although the muang continues to gain fans and popularity on social media, experts recommend following the advice of healthcare professionals to ensure safety and well-being.
