Mewing, a practice popularized online, focuses on achieving proper tongue resting posture against the roof of the mouth to influence facial structure and jawline definition. While this technique aims to improve overall “oral posture,” the question of whether it should cause discomfort is common for beginners. Mewing should not cause sharp or persistent pain, but a feeling of mild muscle fatigue is frequently reported in the initial stages. This transient soreness is often a sign that the small, underused muscles of the tongue and submental area are being engaged for the first time. The difference between this expected, temporary muscle fatigue and abnormal pain determines if the practice is being performed correctly and safely.
The Mechanics of Correct Mewing Posture
Correct mewing involves maintaining a light, sustained effort to keep the entire tongue sealed against the palate, not a forceful push. This proper posture is composed of three main elements that must be executed simultaneously to avoid strain. The tongue’s tip should rest just behind the front teeth, without actually touching them, in the same position it takes when pronouncing the letter “N”. From this anchor point, the middle and the back third of the tongue must be lifted and suctioned against the roof of the mouth.
Achieving full suction requires engaging the throat muscles, identifiable by saying words that end with the “ng” sound. The correct resting jaw position accompanies this placement: lips are gently sealed, and teeth are lightly touching or slightly apart. The goal is to maintain this posture consistently, making it feel like a natural, light effort rather than a strenuous exercise. Applying excessive force to accelerate results is a common mistake that leads to pain and contradicts the habitual nature of correct mewing.
Identifying Expected Discomfort vs. Warning Signs
Initial discomfort is normal when training any muscle group, but this sensation must be distinguished from actual pain. Expected discomfort manifests as muscle soreness or fatigue in the submental muscles underneath the chin. Mild, generalized tension across the cheeks or temples may also occur as facial muscles adapt. This mild pressure on the roof of the mouth is also common as the tongue learns to maintain consistent contact with the palate.
These sensations should diminish quickly upon rest and become less noticeable over the first few weeks as muscles strengthen. In contrast, a sharp, localized pain is a warning sign that the technique is incorrect or that an underlying issue exists. Pain concentrated in the temporomandibular joint (TMJ), located in front of the ear, is a concern, often caused by clenching the jaw or uneven pressure. Other red flags include a persistent headache, clicking or popping sounds when moving the jaw, or pain that radiates into the neck or ears. If any warning signs appear, stop the practice immediately, as they suggest undue stress on the jaw structure or dental alignment.
When to Seek Professional Guidance
If persistent, sharp pain or any warning signs occur, seek the guidance of a qualified medical professional. Self-diagnosing structural issues based on online trends is risky, and a professional evaluation can prevent damage. Orthodontists or dentists can assess the alignment of the teeth and jaw structure, ensuring mewing does not exacerbate pre-existing conditions like TMJ disorders.
Consulting a myofunctional therapist is beneficial, as these specialists focus on the correct function of the tongue and facial muscles. They confirm if the tongue posture is correct and not causing a tongue thrust or adverse movements that could push teeth out of alignment. If breathing difficulties or persistent pain are involved, an Ear, Nose, and Throat (ENT) specialist may be needed to rule out underlying issues in the airway or sinuses. Temporarily stopping the practice and seeking professional assessment is the safest course of action if any pain is felt.
