Mewing 101 | History | Does it work | Backed by Science? | In pop culture

Mewing is a facial restructuring technique that was popularized by orthodontist John Mew. Mewing is said to work by training the facial muscles and jaws to rest in a more upward position. This, in turn, is supposed to create a more aesthetically pleasing appearance with more symmetric facial features, as well as improve overall health. It has had a recent resurgence in the media, mostly by beauty bloggers and reality stars but has been around since the 1970s. Keep reading to learn all about mewing and if it works.

What is mewing?

Mewing is an oral posture training technique that was developed in England. The goal of mewing is to achieve and maintain a protruded lower jaw, or “mewed” look. To do this, you use correct tongue posture, breathing through your nose, and different methods of chewing and swallowing to help achieve a more aesthetically pleasing look by holding the lower jaw forward. It was created as an alternative to traditional orthodontic braces and has become popular in certain circles recently.

What is the history of mewing?

Mewing was developed by British orthodontist Dr. John Mew and is still touted by his son, also an orthodontist, named Michael Mew. He observed that many of his patients had misaligned teeth and poor jaw structure, which he believed could be corrected through oral posture training. Mew focused on having a strong jawline in order to achieve a look he called “cupid’s bow lips.” This mewed look is popular in the modeling and acting industries, where it creates an image of high cheekbones and symmetrical facial structure that can be captured even on film.

How does mewing work?

Mewing works by holding the lower jaw in a protruded position. This helps to realign teeth over time, as well as improve the overall appearance of the face. It is important to note that practitioners of mewing say that it should be done correctly in order to be effective as incorrect mewing can actually lead to more problems.

There are several basic things you must do to mew correctly. First, you must practice proper tongue posture by keeping your tongue flat against the roof of your mouth. Next, you must breathe through your nose at all times, which helps to keep the tongue in place. You must also keep your lips closed and only open them when necessary for eating or speaking. Finally, you should chew your food slowly and thoroughly, and once your food is thoroughly chewed you should only use your throat muscles to swallow. You should also be cognizant to not move your lips when swallowing too.

People believe mewing can help with a variety of orthodontic problems, including crooked teeth, crowded teeth, overbite, underbite, and crossbite. Some people even claim it can help with TMJ disorders and sleep apnea.

Is mewing backed by science?

Mewing has been widely criticized for lacking scientific evidence to support its claims of re-aligning teeth and improving oral posture. However, mewers point out that the technique is not meant to be used as a stand-alone treatment but rather in conjunction with orthodontic treatment. Despite these claims, mewing is still criticized because it can be harmful if done incorrectly and there are no scientific studies that prove mewing’s effectiveness for realigning teeth or improving oral posture.

Please note that there are no peer-reviewed scientific studies that prove mewing works. There is some scientific evidence to suggest that mewing may be beneficial although most evidence for mewing is anecdotal. Doctors and orthodontists even use some of these techniques, but not all of them, as proposed by Mew for different things, but that does not mean mewing, as a whole, works. Also, it is very unlikely that any of these exercises change your jawline although there are exercises that can strengthen your jaw muscles, should you want that. 

Are there any adverse effects from mewing?

Mewing is generally safe when done correctly. However, mewing practitioners proclaim that it can be harmful if done incorrectly. Incorrect mewing can lead to problems such as teeth misalignment, jaw pain, and headaches. It is important to consult with an orthodontist or doctor before starting mewing in order to learn how to do the technique correctly or if it is even necessary. If you are suffering from sleep apnea or any other breathing problems it is not recommended that you use mewing to help treat it as there is no scientific basis for it. If you have these problems, please talk to your doctor or health care provider to learn about the best treatment plans for you.

Should I start mewing?

Mewing is not for everyone. There are no scientific studies that prove mewing’s effectiveness, so if you are looking for a treatment plan that has proven results, mewing is not the right choice for you. However, if you are looking for a technique that may help improve your oral posture and alignment over time, mewing may be a good option for you. Consult with an orthodontist to learn more. As noted above, do not use mewing as a treatment plan for any health issues like sleep apnea or breathing problems.

Mewing in popular culture

Mewing has caught on in popular culture and mewing videos can be found on social media and YouTube. It has regained some popularity due to Dr. Mew's son, Mike Mew, who promotes his father's method for good oral posture. He also has been linked with the Incel movement. Incel is short for involuntary celibate and it refers to men who blame women for them not being sexually active. A video of Mike Mew explaining mewing went viral on an Incel message board and then Mike joined the forum to answer some of their questions. Almost a decade later, mewing is becoming popular in many circles and its popularity continues to increase.
