Do you experience jaw locking? Jaw locking or locking of the TMJ (Temporomandibular Joint) can be a symptom of a variety of conditions, many of which can be worsened by poor posture. Posture plays a vital role in the function and stability of the temporomandibular (TMJ) and can be a primary factor in jaw locking. This article aims to explain the connection between posture and jaw locking, how poor posture can contribute, and some tips for proper postural alignment to help relieve TMJ pain.
Anatomy of the TMJ and Its Function
The temporomandibular joint (TMJ) is a complex structure made up of muscles, ligaments, cartilage, and bone. The TMJ’s main function is to move in different directions to allow the mouth to open and close and for the jaw to move side to side. It’s a joint that is used frequently; during eating, speaking, and yawning among other activities.
When functioning optimally, the TMJ moves smoothly without clicking, popping, or locking of the jaw. When the TMJ does not function as it should, it can cause a number of symptoms including:
- Pain or tenderness of the jaw, neck, and face
- Headaches, ear pain, and dizziness
- Difficulty opening and closing the mouth
- Difficulty chewing or biting
- Jaw locking or popping
The Role of Posture: How Poor Posture Can Activate Jaw Locking
Poor posture is the culprit of many musculoskeletal conditions, including jaw locking. Poor posture can lead to muscle imbalances and increased tension in the muscles surrounding the TMJ. When the muscles around the jaw tense up, it can prevent the jaw from moving freely.
Some of the most common postural contributors to jaw locking are forward head posture, rounded shoulders, and an anterior pelvic tilt. These postures can not only affect the way TMJ muscles contract, but they can also lead to decreased blood flow to the area, increased tension in the neck and shoulders, and even ligament laxity due to the increased stress in the area.
Tips for Proper Postural Alignment
The best way to alleviate jaw locking and prevent it from returning is to correct postural imbalances. Here are a few tips for proper postural alignment:
1. Strengthen Muscles that Contribute to Proper Posture
Having a strong, balanced musculature throughout the body can help align the body properly. Focus on strengthening the upper back muscles, core muscles, and glutes for optimal posture.
2. Sit and Stand Taller
Too often people slouch, and this can lead to poor posture. Focus on sitting and standing up tall and lengthening the spine. Try to align the ears, shoulders, and hips to properly position the body. Practicing good posture is essential in preventing jaw locking.
3. Take Regular Breaks from Prolonged Sitting
Long durations of sitting can lead to muscle fatigue and forward head posture. Take breaks from sitting every 20-30 minutes to stand, stretch out the body, and move around. This will help reduce muscle fatigue and can prevent tightness in the muscles surrounding the TMJ.
4. Use Proper Ergonomics when Working
It is essential to use proper ergonomics when working at a desk to prevent muscle fatigue and poor posture. Make sure the computer screen is at eye level and arms are at a 90-degree angle. Try to avoid looking down at a computer screen or phone for long periods of time as this can lead to poor posture.
In Conclusion
Jaw locking can be a debilitating condition and can be worsened by poor posture. Proper posture is essential for TMJ health and can play a critical role in preventing and relieving jaw locking. Taking steps to strengthen muscles that contribute to proper posture, practicing good posture, and using proper ergonomics when working can help prevent and alleviate jaw locking. If symptoms persist, it is important to seek guidance from a healthcare professional.
