Mewing is a social-media term for maintaining a particular resting tongue posture, usually with the tongue against the roof of the mouth. Good oral posture can be practiced gently, but there is no strong evidence that mewing can dramatically reshape an adult jawline or replace orthodontic treatment.

Updated for a U.S. audience in 2026

If you are trying to learn how to mew properly, the safest approach is to think of it as relaxed tongue posture rather than a workout for your jaw. Your tongue should rest comfortably against the palate, your lips should meet without strain, and your jaw should stay relaxed rather than clenched.

What mewing should not involve is forcefully pushing the tongue upward for hours, biting the teeth together, creating jaw pain, or trying to move teeth without professional supervision. The American Association of Orthodontists cautions that tongue position alone has not been shown to sculpt the jaw or correct crooked teeth.

Key Takeaways

• Mewing is a popular term for holding the tongue against the roof of the mouth as a resting posture.
• A comfortable version involves the tongue resting broadly on the palate, lips gently closed, jaw relaxed, and breathing through the nose when the nasal airway is clear.
• Do not press as hard as possible, clench your teeth, or continue if the technique causes jaw, tooth, tongue, or facial pain.
• There is not strong scientific evidence that mewing can permanently reshape an adult face or create a sharper jawline.
• Tongue posture can matter in oral development and swallowing, but structural dental or jaw problems require professional evaluation.
• People with chronic nasal blockage, sleep-disordered breathing, tongue-tie concerns, TMJ pain, or orthodontic problems should not use mewing as a substitute for treatment.

What Is Mewing?

Mewing is an online tongue-posture practice in which the tongue rests against the palate. Supporters often claim it improves jaw definition, breathing, or dental alignment.

Dentists and speech professionals do assess tongue posture and swallowing. The unsupported leap is the claim that an adult can substantially remodel facial bones simply by holding the tongue in one position.

How Do You Mew Properly?

If you want to experiment with mewing, use a relaxed technique rather than force. The goal is a neutral resting position that feels sustainable.

Step	What to do	What to avoid
1. Relax your jaw	Let the jaw rest naturally with no squeezing	Do not clench or grind your teeth
2. Close your lips gently	Bring the lips together without pursing	Do not create facial tension
3. Place the tongue up	Rest the tongue broadly against the palate	Do not jab or press hard into the roof of the mouth
4. Keep the tip behind the front teeth	Place the tip just behind, not on, the upper front teeth	Do not push the teeth forward
5. Breathe comfortably	Use nasal breathing if your nose is naturally clear	Do not force nasal breathing through significant blockage
6. Maintain posture lightly	Think gentle contact, not exercise-level pressure	Stop if you develop pain, clicking, headache, or tooth pressure

Step 1: Start With a Relaxed Jaw

Before thinking about tongue position, relax the muscles around your temples, cheeks, and jaw. Your teeth do not need to be squeezed together. A relaxed mouth posture should not feel like you are performing a strength exercise.

Step 2: Rest the Tongue Against the Roof of the Mouth

Bring the tongue upward so more than just the tip makes contact with the palate. The tip can rest slightly behind the upper front teeth, while the middle and back of the tongue sit comfortably upward.

The tongue should not press directly against the front teeth. Repeated pressure on teeth can be a problem, especially if you are also trying to push the jaw forward or create force.

Step 3: Use a Gentle Suction Hold

Some people find it easier to create light tongue-to-palate contact by swallowing once and noticing where the tongue naturally finishes. A mild suction feeling can help the tongue stay up without active hard pressing.

If holding this posture makes your tongue tired within minutes, you are probably using more muscular force than necessary.

Step 4: Keep the Lips Closed Without Tension

The lips can meet softly while the facial muscles stay relaxed. If keeping the mouth closed feels difficult because you cannot breathe well through your nose, that is a reason to address the airway problem rather than force the posture.

Step 5: Breathe Through Your Nose When Comfortable

Normal nasal breathing helps keep the mouth from hanging open, but it should not become a struggle. Allergies, a deviated septum, enlarged tonsils or adenoids, chronic congestion, and other airway problems can make nasal breathing difficult.

If you routinely sleep with your mouth open, snore loudly, wake gasping, or feel unusually sleepy during the day, do not assume mewing will fix the cause. These symptoms can deserve a medical or dental sleep evaluation.

How Hard Should You Press When Mewing?

You do not need maximal pressure. In a neutral resting posture, the tongue is not supposed to act like an orthodontic appliance that you consciously drive into the palate all day.

Hard pressing can create fatigue or discomfort and may encourage jaw clenching. If your teeth feel sore, your jaw starts clicking, or you develop headaches after practicing, reduce the effort or stop.

Should Your Teeth Touch While Mewing?

Do not clench. The jaw should remain relaxed. Some descriptions of oral resting posture allow the teeth to be lightly together, while others describe a small freeway space between the upper and lower teeth.

The important point is that you should not squeeze the teeth together to make mewing feel more intense. Persistent clenching can aggravate the jaw muscles and temporomandibular joints.

Does Mewing Actually Change Your Jawline?

There is no good evidence that mewing can reliably create a major permanent change in adult jaw shape. Facial appearance is influenced by genetics, bone structure, body composition, dental alignment, muscle anatomy, age, and many other factors.

The American Association of Orthodontists states that changing tongue placement is not enough to reshape the jawline, move misaligned teeth, or replace orthodontic treatment. Read the AAO explanation of mewing claims and risks.

Photos posted online are also difficult to evaluate. Lighting, camera angle, neck position, facial expression, weight change, and normal maturation can all make a jawline look different without proving that tongue posture changed the facial skeleton.

Does Tongue Posture Matter at All?

Yes, but this is more nuanced than viral before-and-after claims. The tongue is part of the muscular environment surrounding the teeth and jaws, and clinicians do consider tongue posture, swallowing patterns, and oral habits when evaluating some orthodontic problems.

A peer-reviewed review of tongue posture and dentofacial development describes associations between tongue position, dental arch form, swallowing, and malocclusion, while also emphasizing the complexity of cause and effect. See the peer-reviewed review on tongue posture and dental development.

That does not mean a self-directed posture routine can reverse established skeletal or dental problems. If teeth are crowded, the bite is misaligned, or the jaw relationship is abnormal, an orthodontist can determine whether treatment is actually needed.

What Are Common Mewing Mistakes?

• pressing only the tongue tip upward while the rest of the tongue stays low
• pushing the tongue directly against the front teeth
• clenching the jaw to make the technique feel stronger
• forcing the lower jaw forward
• using painful pressure because you think more force produces faster results
• trying to breathe through a blocked nose instead of treating congestion
• expecting a few weeks of tongue posture to produce major skeletal changes
• continuing despite jaw pain, tooth soreness, headaches, clicking, or bite changes

Can Mewing Cause Jaw or TMJ Pain?

The tongue resting gently against the palate should not hurt. Problems are more likely when people combine mewing with clenching, prolonged muscle tension, or consciously forcing the jaw into a new position.

If you already have jaw clicking, locking, facial pain, or frequent tension headaches, adding more jaw-muscle effort can make symptoms harder to interpret. For head and neck discomfort, gentle self-care may be more appropriate than forceful jaw exercises.

Mewing also should not be treated as a whole-body posture treatment. If pain or nerve symptoms elsewhere are affecting how you move, address those separately rather than trying to correct them through jaw position.

Who Should Be Careful With Mewing?

• people with active TMJ pain, jaw locking, or significant jaw clicking
• people wearing braces, aligners, retainers, or other orthodontic appliances
• people with a known malocclusion or unstable bite
• people with chronic nasal obstruction or difficulty breathing through the nose
• people with suspected sleep apnea or significant snoring
• people with tongue-tie or swallowing problems who may benefit from professional assessment
• children whose facial growth or bite is a concern, since growth-related treatment should be supervised by qualified clinicians

When Should You See an Orthodontist or Dentist?

Make an appointment if your concern is more than simple tongue posture. An orthodontist or dentist can evaluate crowding, crossbite, overbite, underbite, open bite, jaw asymmetry, tooth movement, and other structural issues.

You should also seek care if self-directed mewing causes persistent tooth pressure, new bite changes, jaw pain, locking, headaches, or difficulty chewing. Those are signs to stop experimenting rather than increase the pressure.

Common Questions About How to Mew Properly

Where should your tongue sit when mewing?

The tongue should rest broadly and comfortably against the roof of the mouth, with the tip just behind the upper front teeth rather than pushing on them.

Should mewing hurt?

No. A gentle resting posture should not cause jaw pain, tooth soreness, headaches, tongue pain, or facial fatigue.

How long does it take for mewing to change your face?

There is no reliable scientific timeline because substantial adult facial reshaping from mewing has not been demonstrated in strong clinical evidence.

Can mewing fix crooked teeth?

No. Do not use tongue pressure as a substitute for orthodontic treatment. Tooth movement should be planned and monitored by a qualified dental professional.

The Bottom Line

If you want to know how to mew properly, keep the technique simple: relax your jaw, close your lips comfortably, let the tongue rest broadly against the palate, keep the tip just behind the upper front teeth, and breathe normally through the nose when your airway is clear.

Do not turn mewing into a force exercise. There is no strong evidence that hard tongue pressure can dramatically reshape an adult jawline, and it should not replace orthodontics, treatment for nasal obstruction, or care for TMJ symptoms.

Comfortable tongue posture can be a reasonable oral habit, but the safest goal is normal function rather than chasing dramatic facial changes from an unproven technique.
