The relationship between the resting tongue position and the shape of one’s jawline has been a much-speculated topic online. The proper tongue posture technique developed by Dr. Mew has become known as “mewing.” Do you think you know everything you need to know about mewing?
Although we always need to be wary of junk ‘alternative’ science, the ideas put forth by Dr. Mike Mew and the field of orthotropics have been incredibly popular. Not only are they plausible, but they’ve achieved considerable results for users. Does mewing even work? Can it give you a more defined jawline and profile?

What Is Mewing?
Mewing is a proper oral posture technique that seeks to better the orientation of the face and jawline by altering your unconscious, resting tongue position. By mewing, you are training your tongue to rest on the roof of your mouth and making it a part of your muscle memory.
As someone who did not find this intuitive at first, I’m surprised to find out that most people already naturally rest their tongues on the roof of their mouths. However, if you’re one of the few who don’t already do this, mewing might be a revelation.
Resting your tongue on the floor of your mouth is actually an abnormality that destabilizes the opposing forces of the mandible and maxilla (the lower and upper jaw). It results in mouth-breathing, a longer face, a more hunched poise, and an overall worse appearance.
Before we get into specifics, I should make clear that mewing is not a new trendy thing in cosmetics to make you instantly look better. Rather, not mewing is what’s making people’s appearances worse. Mewing is simply a form of corrective therapy aimed at bringing our tongue posture back to where it should be naturally sitting.
Reasons to Start Mewing
- Perhaps you’re now realizing that you rest your tongue on the floor of your mouth unconsciously and want proper tongue posture.
- If you’re mainly a mouth-breather.
- You have an ill-defined jawline and want to improve your face.
- You have difficulty swallowing or obstruction in your breathing.
- If you have sleep apnea.
- If you have a narrow palate and teeth crowding.
- You have a mild underbite.
- You want to appear more confident and correct your overall posture.
- Your orthodontist has recommended it to you
Who Is Dr. Mew?
Dr. Mike Mew is an orthodontist who was trained in London and manages his own orthodontic clinic there. He is a third-generation dentist who received his orthodontic training from Aarhus University in Denmark under the mentorship of Professor Birte Melsen. Throughout the 1990s, Dr. Mike Mew was a practicing dentist at the Royal London Hospital.
Dr. Mike Mew’s father, Dr. John Mew, is credited with beginning the field of orthotropics. Orthotropics is a branch of medicine that follows the philosophy that one should treat the face rather than just the teeth.
The field has a significant overlap with the existing field of myofunctional therapy, a holistic approach that treats disorders of the face and mouth. Orthotropics is represented internationally by the International Association of Facial Growth Guidance (IAFGG). In the last decade, the mewing technique has been popularized in large part by his son.

It’s understandable, then, why
How to Do Mewing Correctly
Mewing is all about proper tongue posture. As explained by Dr. Mike Mew, here is the basic definition:
Yes, that’s really it. But it’s a lot easier said than done.
To do mewing correctly you need to have your entire tongue on the roof of your mouth. That includes the back of the tongue, too, so your tongue should fit right between your molars. This might even be tiring for you initially since your tongue muscles are too weak. If you are mewing correctly, you should feel some pressure in your mid-face, chin, jawline, and palate.
The effects of mewing on your jaw are illustrated below.
Mewing might seem a bit strange at first. You essentially have to retrain your brain to completely rewire its existing facial resting position. Tongue posture is a hard habit to break, especially if you’ve been doing it incorrectly all your life.
The good news is that, after practicing mewing consciously for weeks, it will eventually become like muscle memory. It’ll get much easier. You will also see demonstrable improvements to your face over time. Your face’s entire posture and orientation will be more symmetrical.
You will feel your entire face come forward. It really is quite surprising how a simple proper tongue posture can do all this. If you think about it, though, it makes sense: your tongue holds your mouth, and your face, in balance. Your jawline muscles and tongue are opposing forces which must be synchronized properly.

Mewing and Swallowing (Super Important!)
Mewing and proper tongue posture also rely on you to swallow and drink correctly. It is through the act of swallowing that mewing applies a few pounds of force to the roof of your mouth. This force is what will be responsible for expanding the roof of your mouth—and will ultimately bring noticeable changes to your appearance.
To swallow correctly while mewing, simply press the tongue firmly against your palate while swallowing. Keep your facial expression unchanged. As you feel your thyroid rise with each swallow, you will also feel your tongue press against the roof of your mouth.
Note: If you’re not swallowing correctly while mewing, you will not see the best results. You have to learn to swallow with your tongue. It’s crucial.
Maintain Your Posure
It should also be noted that mewing should also be
Good posture should be like second-nature, just like mewing.
Mewing’s simplicity should not cause us to second-guess its proven track-record in correcting facial asymmetry, ill-defined jawlines, and sagging jowls. Coupled with working out the masseter muscle through jawline exercises, mewing is a technique that is foundational to a more defined profile. The end result is a more balanced, lifted appearance with a defined jaw and profile.
All the Evidence We Could Find for Mewing
So, you might be wondering: where’s the proof mewing even works?
Proper tongue posture is nothing new nor was it invented by Dr. Mike Mew. It’s been part of dentistry for well over a century. Myofunctional therapy, which trains patients
Although the importance of oral posture is still understudied, there have been some clinical studies done along with some first-hand accounts of its success. However, let’s first discuss the basic developmental theory behind mewing and then present the evidence.
Breaking It Down: How Mewing Works
Contrary to what you may have initially thought, the skull is actually not one large bone. It is made up of sutures, the connective tissues between the skull’s bones. This means that the skull can in fact change over time.
As an example of this, Dr. Mew often mentions how motor neurone disease deteriorated the shape of physicist Stephen Hawking’s skull over time. Due to no muscle movement in his face on account of his condition, his entire skull sagged further and further downward with age and changed shape. This indicates there is indeed some elasticity in skulls.
Because the skull is made up of all these sutures, mewing is actually about balancing the muscles in the face. This naturally causes slight changes in facial structure. Ultimately, what holds the facial balance together is the
By mewing, you apply pressure on the maxila and thus change it over time. The changes to the face shape based on the position of the maxila is demonstrated below.
There is a small, but growing, amount of evidence currently available on proper tongue posture. Take a look at the evidence below for yourself and draw your own conclusions. The topic of proper tongue posture still remains largely understudied.
- In a study conducted in 2014 published in the Korean Journal of Orthodontics, the corrective tongue posture technique was able to correct an overbite and bring the entire face forward. After a two-year relapse using retainers, the mewing technique produced lasting effects for 10 years according to the study. However, this particular patient used a tongue elevator to ensure that his tongue was on the roof of his mouth rather than stick to it himself.
- A 2018 study in the journal Radiology and Oncology found significant evidence for “tongue posture” curing anterior open bites in preschool children. The study recommends tongue posture techniques (like mewing) for early childhood development.
- A 1997 study published in the Journal of Oral & Facial Pain and Headache found tongue posture on the roof of the mouth to be linked to stronger temporalis and suprahyoid muscles, both required for mastication.
- In a 2009 study published in the OOOO Journal (for Oral Surgery, Oral Medicine, Oral Pathology, and Oral Radiology), proper tongue posture was monitored in participants with an average age of 19.6. Results found “significantly more activity in the temporalis and suprahyoid muscle regions as well as a significant reduction in heart rate variability when the tongue was positioned on the palate compared with tongue position on the floor of the mouth.”
- In a 2010 study published in the European Journal of Orthodontics, a tongue-repositioning maneuver was found to reduce snoring in patients with a normal BMI when combined with an oral shield.
- A 2016 study published in The Angle Orthodontist journal concluded with the following: “It is suggested that the development of a correct tongue-to-palate swallowing pattern may form and widen the dental arches during craniofacial development to suit the tongue, while the persistence of a swallowing pattern that includes a pressing of the tongue between the teeth may not.”
- In a “highly surprising” 2016 pilot study published in the Muscle, Ligaments and Tendons Journal, a proper tongue position on the palate was found to be linked to a “30% significant increase of knee flexion peak torque.” In other words, tongue posture is linked to the posture of your entire body.
- A 2018 study presented at the 21st Annual World Dentral Summit looked at 90 subjects and found that “tongue posture has a significant effect on sagittal jaw relationship and dental arch widths.”
- One commonly-cited piece of evidence (1999) cited by Dr. Mew is the case of the Creed twins. One twin underwent orthotropic treatment focusing on tongue posture while another opted for a traditional dental appliance. Just using a simple tongue posture adjustment, the outcomes were drastically different for each twin as shown below.
There is still much clinical work to be done on mewing and proper tongue posture. However, some of this information provides us with concrete evidence that proper tongue posture produces distinguishable effects.
Other Scholarly Evidence
- The Dental Academy of Continuing Education lists in their course on muscle memory the importance of proper tongue posture. They define proper tongue posture as “the apex of the tongue should be resting just lingual to the maxillary anterior teeth and on the incisive papilla of the hard palate.” The course document cites Hanson, M. L., & Mason, R. M. (2003). Orofacial Myology International Perspectives (Second ed.). Springfield, Illinois: Charles C Thomas.
- With 36 citations, this report published by the Oral Health Group finds mouth breathing to be intimately connected to low tongue posture.
- Stanford’s biologist and population studies specialist Paul Ehrlich and orthodontist Sandra Kahn have recently co-authored a book Jaws which discusses the “hidden epidemic” of recessed jaw development. The book affirms the importance of proper tongue posture.
There are also countless before-and-after photos online which demonstrate change over time due to mewing. Although anecdotal evidence should be met with skepticism usually, the growing amount of before-and-after evidence is becoming more and more overwhelming.
Mewing Before and After Photos
The before and after photos of these mewing results definitely show some noticeable improvement.
When to Expect Results
Because mewing is a corrective therapy technique for your face, you won’t see results immediately, of course. However, many have reported noticeable changes to their midface, jawline, and chin in just 6 months to a year. Also, once mewing becomes an unconscious habit, you won’t even need to think about it anymore: it will just become a part of your mouth’s resting position with the benefits multiplying over time.
It takes time to correct a lifelong bad habit – be patient!
Since mewing is akin to rewiring your mind to rest your tongue differently, it’s not a fast solution by any means. Instead, it is a therapeutic correction that may in some cases even take a year or more to see results. If you’re correcting a lifelong bad habit you never knew you had, that takes time: so keep at it and you will see demonstrable benefits in your swallowing, breathing, and jawline definition once mewing becomes like second nature.
In short, be patient.
Am I Too Old to Start Mewing?
It should be noted that mewing best works for growing faces, especially in children going through puberty. However, don’t be saddened if you’re an adult reading this. Mewing has seen some success rates in adults as well, but at slower rates. This is because the face is far more elastic than we give it credit for.
Dr. Mew himself is a
Why Do We Need to Do Mewing in the First Place?
It’s quite surprising actually how many people rest their tongues on the floor of their mouths thinking it is normal.
This bad habit may have emerged from mouth-breathing, eating far too many soft foods as a kid, or a whole host of other possible reasons. You probably may have never even considered this a problem until now.
Just by making a simple adjustment and resting your tongue on the roof of your mouth, you engage your entire midface to come
The effects of this simple technique are numerous and they include:
- a healthier mode of swallowing
- a slightly more defined jawline over time
- an improvement in posture overall.
Is Our Modern Lifestyle to Blame?
The main reason why more of us have improper tongue posture than ever before is simply due to our modern lifestyles.
The 20th century brought processed foods, breastfeeding supplements, and other factors. Our new sedentary lifestyles, both at home and at work, have ruined our postures. Hunched over our screens, more of us commonly mouth-breathe and have poor posture. Our modern lifestyle has made us utilize less of our masticating muscles to our detriment.
It has been found that this problem is especially prevalent in the West. In fact, there has been an exponential ‘epidemic’ of patients requiring orthodontic treatment in the past century. Fossil records have shown that pre-modern man had far
Resting your tongue on the roof of your mouth is the correct way to develop and balance your face, but unless you’re conscious of it you would have never have known. That’s why “mewing” has been called a form of corrective therapy: you are in effect trying to consciously retrain yourself to rest your tongue in the correct position. Mewing is simply the return to the natural resting position of the tongue as it should be.
Supplements to Boost Gains
There are a few supplements to try while mewing to keep yourself in healthy and top shape. These are just some general recommendations which we have found to complement the benefits you want out of mewing.
- Vitamin K2 promotes bone plasticity and cardiovascular health (as proven in clinical studies).
- Vitamin D3 has a direct relationship with bone health.
Your best bet would be to buy a supplement that has both vitamin K2 and vitamin D3. Sports Research D3 + K2 supplement with coconut oil (as shown below) is our recommendation, but this other option by Zhou Nutrition is also a good pick.
Some other important supplements for mewing are magnesium & B vitamins:
- Magnesium is your best friend for muscle stamina. Pick yourself up some high absorption magnesium so you get the full benefit.
- B vitamins which will help your body convert more nutrients into energy. This complete formula by Sapien Labs includes B1, B2, B3, B5, B6, B7, B9: the complete B vitamin supplement.
Better Your Profile By Chewing Mastic Gum
Dr. Mew has mentioned chewing gum as a compliment to mewing in many of his videos. By chewing durable gum, you can strengthen your masseter muscle and give your jawline further definition. You should view mewing as fixing the internal orientation of your face which allows jaw workouts like chewing gum to be much more effective and comprehensive.
The best gum to chew with mewing is mastic gum. Not only does it boast many health benefits, but it is also incredibly durable even if you were to chew it for days straight. There’s a reason mastic gum was once compared to gold two-thousand years ago; it has been associated with many wellness properties and has been linked to de-stressing, meditative practices.
If you are looking to go the extra mile to give your jawline definition while mewing, mastic gum is your best bet. Here are our favorites to try:
- Greek Chios (Xios) Mastic Gum: One of our top picks, this gum is all-natural and practically lasts forever.
- ELMA Classic Chios Mastic Gum: This is the oldest chewing gum in the ancient world which is done justice by this top-quality mastic gum.
- Pure Greek Mastic Gum:
- Krinos Imported Mastic Gum: Made of sun-dried mastic extract, this is another authentic option from Greece.
Be sure to chew 2-3 hours every day to start. Initially, the taste will be bitter but will become more pine-tasting as you chew. If you feel soreness in your jaw after chewing for a few days, don’t overdo it: be sure to take a break. However, over time, you will find that this soreness will cease and your jawline will develop more strength. This will, in turn, give your jawline definition and push your face forward.
An Alternative: Falim Gum
Some people don’t like the taste of mastic gum, however. Alternatively, you can also try Falim 100 Pieces Sugar-Free Chewing Gum which is just as durable as mastic gum. The texture of Falim gum is similar to regular gum, which some prefer. Falim gum, however, boasts none of the health benefits of mastic. Falim comes in many flavors like strawberry, mint, and watermelon, mint or plain taste best (in my opinion).
