Introduction

We all like to look beautiful. One of the common or sought-after beauty trends of modern times is a sharp jawline and facial features. Needless to say, people are doing various facial exercises to gain such features. One of the popular exercises among these is mewing.

What Is Mewing?

Mewing is a technique that involves positioning the tongue against the roof of the mouth, and it is claimed to contribute to a more defined and sharp jawline. Also, according to some people, it helps improve facial features.

How to Mew Correctly?

The following techniques are step-by-step guidelines on how to mew correctly;

  1. After keeping your mouth closed. Gently position your lower front teeth just behind or near your upper front teeth. With your lips together, press your tongue against the roof of your mouth, ensuring that your jaw muscles are engaged.

  2. Place the tip of your tongue slightly behind your upper front teeth, mimicking the position to articulate the "n" sound.

  3. Maintain this posture for a minimum of 20 seconds and repeat it several times throughout the day. Mewing involves pressing your tongue flat against the roof of your mouth.

This practice is believed to gradually assist in realigning your teeth and enhancing your jawline. The science behind this is based on the generation of a vacuum inside the mouth. This vacuum creates a negative pressure area inside the mouth and a positive pressure area outside the facial muscles. This difference in the pressure helps to align the facial muscles and jawbones. To effectively mew, it is essential to relax your tongue and ensure it is fully positioned against the roof of your mouth, including the back portion of the tongue.

Mastering this technique may require regular practice, as many individuals are accustomed to allowing their tongues to rest away from the roof of the mouth without conscious thought. With time, your muscles will adapt to the correct mewing position, making it a natural habit. In fact, it is advisable to maintain this tongue position consistently, even while consuming liquids.

However, like many self-improvement methods that appear overly optimistic, mewing has its limitations — results may take years to manifest. Maxillofacial deformities are generally addressed through surgical or orthodontic interventions, so it is important not to expect immediate corrections from occasional mewing alone.

Does Hard Mewing Work?

Soft mewing versus hard mewing is a topic that often leads to confusion among teenagers. Many believe that pressing their tongue firmly against the roof of your mouth, known as hard mewing, will exhibit quicker and faster results. However, this method is not advisable and can cause problems. Excessive pressure during hard mewing on the palate may cause a high arched palatal vault, which might cause difficulty in talking and respiration. The key to effective mewing is to keep it effortless rather than treating it like a workout. It is all about achieving the right posture with minimal strain by creating a gentle suction in your mouth, which is more effective than applying excessive pressure. The ideal force for moving teeth and bones should be light, around a few grams per tooth, and maintained over a longer period.

Does Mewing Actually Work?

According to doctor Dr. Mike Mew soft diet and lifestyle changes are the main causes of reduced jaw growth. According to him, this is the main cause of a blunt jawline in modern times is related to the increased soft diet of the children. He proposed proper growth of the facial muscles and jaw bones is essential for sharp facial features and can be achieved by mewing jawline exercises. However, current research supports the fact that differences in oral pressure do affect jaw development and the development of the muscles. Along with this, proper chewing and chewing hard foods can also provide beneficial effects in the development of the jaw bone. Despite this, no modern research has pointed out the efficacy of the mewing. However, there is no scientific evidence supporting this claim.

What Are the Benefits of Mewing?

As already discussed there is no proven scientific evidence regarding mewing benefits. Despite this, many clinicians, influencers, and researchers have pointed out several benefits of mewing. According to them, the benefits of mewing include;

  1. Correction of Alignment of Teeth: Mewing is believed to help widen the jawline, giving your teeth more room to align on their own. It also helps in the proper growth of the lower and upper jaw.

  2. Prevention of Mouth Breathing: Mewing exercise for the jawline keeps the lips together and prevents the habit of breathing through the mouth. As a result, it helps in nasal breathing and prevents sinusitis. Also, it is effective in preventing frequent nasal blockage, cough, and cold. Ideally, as one gets used to this position, it should help cut down on mouth breathing,

  3. Tackle Sleep Apnea: Sleep apnea causes snoring and deficiency of oxygen supply during sleeping. By minimizing mouth breathing, mewing is said to help with sleep apnea and snoring since it encourages the upper airway to open up.

  4. Fix Swallowing Issues: Mewing is thought to engage the muscles needed for swallowing, ensuring your tongue is doing its job right.

  5. Beneficial for Speech Issues: During mewing tongue on the roof the mouth promotes the efficiency of facial and tongue muscles. If you are suffering from speech difficulty, such exercise can be beneficial.

  6. Ease Jaw Pain and Problems: Supporters of mewing argue that it can strengthen and reshape the jaw, potentially reducing jaw pain over time.

Mewing Risks:

Despite significant popularity, mewing can cause significant problems. The risk of mewing include;

  1. Losing of the teeth and loss of support structure of the teeth due to bone loss.

  2. Excessive and improper force of the teeth may cause misalignment of the teeth.

  3. Abnormal jaw positioning causes temporomandibular joint dysfunction.

  4. This may lead to speech and swallowing problems.

How to Identify Problems Developed from Mewing?

Identifying if the person is doing mewing is not an easy job. It actually requires experts like dentists to identify mewing-associated problems. The following changes in the oral cavity can be seen because of mewing;

  1. A deep and high palatal vault.

  2. Excessive mewing may generate excessive force, which may cause inward movement of the upper back teeth.

  3. A change in the tongue position may cause a shift in pronunciation and phonetics.

  4. Mewing may cause a forward position of the lower jaw. Sometimes, it may lead to dysfunction in the jaw movement.

How Can I Get Correct Mewing Habit?

If you want to correct your mewing habit, consult the dentist. Dentists suggest treatment protocols based on the severity of the condition.

  1. Sometimes, an orthodontic appliance is given which prevents the positioning of the tongue.

  2. A mandibular repositioning appliance can be useful in reducing TMJ pain and lower jaw positioning.

  3. For extreme cases, doctors may suggest behavioral therapy to get rid of mewing.

Conclusion:

Mewing creates an alteration of pressure in the oral cavity. According to some clinicians, this helps in sharp jaw lines. Also, this exercise can prevent mouth breathing. Despite all these claims, mewing exercise is not a scientifically proven procedure. On the contrary, it has several drawbacks like malpositioning of the teeth, loosing of the teeth, and TMJ pain. One must consult with the clinician before starting it.
