Is There Scientific Evidence For Mewing?

Mewing, also known as oral posture correction, is a technique that involves positioning the tongue, lips, and jaw in a certain way to improve facial structure and overall oral health.

It has gained popularity in recent years, with proponents claiming that it can lead to improved facial aesthetics, better speech, and improved oral health. But is there scientific evidence to support these claims?

As of now, there is no scientific evidence; but there is an abundance of anecdotal evidence which highlight the effectiveness of mewing.

The Science Behind Mewing

To answer this question, it’s important first to understand the principles behind mewing. Mewing involves using the tongue to push against the roof of the mouth, which is believed to help shape the jaw and improve oral posture. It also involves keeping the lips sealed and the teeth lightly touching in order to encourage proper alignment of the jaw and teeth.

One area where mewing has been suggested to have potential benefits is in the treatment of malocclusion or misalignment of the teeth. It is thought that mewing can help to correct misalignment by encouraging the development of a more ideal jaw shape and position.

However, there is limited scientific evidence to support this claim. While some small studies have suggested that mewing may have a positive effect on malocclusion, more research is needed to confirm these findings.

Is There Scientific Evidence Behind Mewing?

As of now, there is no scientific evidence. However, there are large communities and channels surrounding mewing and its effectiveness, providing many before and after photos showing significant progress. But we cannot confirm that these changes were caused by mewing. Mewing is held in high regard in the self-improvement and beauty niches and is very highly promoted.

So while mewing does not have any scientific evidence, there is an abundance of anecdotal evidence from people who have shown significant progress in their facial structure.

Are Medical Professionals Purposely Ignoring Mewing?

It is important to note that orthodontists, dentists, and other oral healthcare professionals make money off malocclusions and abnormalities of the teeth, jaw, and overall face.

Despite mewing being a massive topic in the healthcare industry. There have been no experiments done in favor of mewing’s effectiveness. However, multiple professional sources indirectly indicate that mewing is beneficial, whether it is about the negative consequences of mouth breathing, the benefits of correct tongue posture, and other main components of mewing.

Medical professionals may be ignoring the existence of mewing and avoid conducting experiments on mewing so that they can continue to profit from the malocclusions and deformities caused by unhealthy oral habits.

While there is no ‘scientific evidence.’ It should also be taken into account that there is no evidence that mewing is inherently bad and that the healthcare industry may be deceitfully labeling mewing as having “no scientific evidence” when it may just be to a lack of conducted experiments.

The Aesthetic Benefits of Mewing

Mewing has also been claimed to have aesthetic benefits, with some proponents suggesting that it can lead to a more attractive facial structure.

Mewing is said to improve forward growth, fix facial asymmetries, and reduce the severities of recessed features such as the maxilla and chin.

Many claim that mewing will give you a ‘hollow cheek’ appearance which is considered very appealing. This is because mewing can affect the cheekbones and improve the jawline.

Limitations of Mewing

Overall, the scientific evidence for the effectiveness of mewing is limited. While it may have some potential benefits for oral health and the treatment of malocclusion, more research is needed to confirm these effects. It is also important to note that mewing should not be used as a replacement for proper dental care, including regular visits to a dentist.

In conclusion, while mewing may have some potential benefits, there is currently limited scientific evidence to support these claims.

As with any new technique or treatment, it is important to approach mewing with caution and to speak with a healthcare professional before starting any new oral care routine.


Mewing has no scientific evidence but is backed up by thousands of anecdotal accounts. But the lack of scientific evidence and experiments may have been purposely manipulated by the healthcare industry.

In the end, there is lot of misinformation on the internet. It’s important to make sure that you trust your sources before you decide to make a dramatic change.
