Mewing: Is This TikTok Trend Dangerous for Your Jaw?

If you've spent any time on TikTok or Instagram in recent months, you've probably seen videos promising a more defined jawline through "mewing." With millions of views and countless transformation testimonials, this viral technique is particularly appealing to teenagers and young adults. But what does science say? And most importantly, is it safe?

What exactly is "Mewing"?

Mewing involves keeping the tongue pressed against the palate, mouth closed, and teeth in light contact. This technique takes its name from John Mew and his son Mike Mew, British orthodontists who promoted this practice as an alternative to traditional orthodontics.

Its followers claim that this tongue position can:

• Redefine the jawline
• Widen the palate
• Improve nasal breathing
• Correct dental alignment issues

These promises are enticing, especially when accompanied by spectacular "before/after" photos. But let's examine the facts.

What science says: the AAO warning

The American Association of Orthodontists (AAO), the world's largest orthodontic association, has officially taken a position on this trend. Their verdict is clear:

"There is no scientific evidence supporting claims of jaw reshaping, and the potential risks outweigh any unproven benefits."

The Cleveland Clinic, a world-renowned medical institution, goes even further: "Mewing doesn't work, and there are other accepted and proven treatments for everything it claims to correct."

An important fact to know: Mike Mew was struck from the British dental register in 2024, following accusations of endangering minor patients who underwent his treatments.

The real risks of mewing

Beyond proven ineffectiveness, mewing can cause real damage:

Why are young people particularly attracted?

The promise of a quick and free facial transformation is irresistible, especially in the age of selfies and filters. But this quest for the "perfect jawline" can have lasting consequences.

It's important to remember that in adults, facial bones are fully developed. Tongue pressure cannot reshape a mature bone structure, contrary to what viral videos suggest.

The alternative: solutions that actually work

If you're concerned about your teeth alignment or the appearance of your jaw, proven solutions exist:

• Traditional or invisible orthodontics: braces, Invisalign, SPARK – treatments supervised by professionals with predictable results
• Palatal expansion: a real orthodontic technique to widen the palate in growing patients
• Tongue posture rehabilitation: performed by a qualified speech therapist if necessary
• Orthognathic surgery: for cases requiring significant bone correction

Our advice

Be wary of "miracle solutions" promoted on social media. Your oral health deserves the attention of a qualified professional, not an influencer without medical training.

If you have concerns about your jaw, bite, or teeth alignment, the first step is always a professional evaluation.
