Jaw Keeps Twitching: Causes, Symptoms, and Treatment Options
Published on December 28, 2024
Key Takeaway
Jaw twitching, while often benign, can be a symptom of various conditions ranging from stress to neurological disorders, and understanding its causes is crucial for proper diagnosis and treatment.
Introduction
Jaw twitching, characterized by involuntary movements of the jaw muscles, can be a bothersome and sometimes concerning symptom. While often harmless, persistent twitching may indicate underlying issues that require attention. This article explores the causes, symptoms, and treatment options for jaw twitching to help you better understand and manage this condition.
Understanding Jaw Twitching
Jaw twitching, also known as masticatory muscle myoclonus, involves brief, involuntary contractions of the jaw muscles. These twitches can vary in frequency and intensity, ranging from barely noticeable to disruptive. Research has shown that normal physiological tremor of the jaw typically occurs at a frequency of 6 to 8 Hz.

Common Causes of Jaw Twitching
Several factors can contribute to jaw twitching:
- Stress and anxiety
- Fatigue
- Caffeine or alcohol consumption
- Nutritional deficiencies (e.g., magnesium, calcium)
- Medications (e.g., certain antipsychotics or SSRIs)
- Temporomandibular joint (TMJ) disorders
- Bruxism (teeth grinding)
In some cases, jaw twitching may be associated with neurological conditions. A study by Tarsy et al. (2006) reported a case of focal jaw tremor that was successfully treated with botulinum toxin injections.
When to Seek Medical Attention
While occasional jaw twitching is usually not a cause for concern, persistent or severe symptoms may warrant medical evaluation. Seek medical attention if:
- Twitching persists for more than two weeks
- Twitching is accompanied by other facial muscle spasms
- You experience pain or difficulty in jaw movement
- Twitching interferes with daily activities like eating or speaking
Diagnosis and Treatment Options
Diagnosis of jaw twitching typically involves a physical examination and medical history review. In some cases, additional tests may be necessary:
- Electromyography (EMG) to measure muscle activity
- Blood tests to check for nutritional deficiencies
- Imaging studies (e.g., MRI) to rule out structural abnormalities
Treatment options vary depending on the underlying cause:
- Stress reduction techniques (e.g., meditation, yoga)
- Dietary modifications (reducing caffeine, alcohol)
- Nutritional supplements if deficiencies are present
- Botulinum toxin injections for severe cases
- Medications to address underlying conditions
- Physical therapy or jaw exercises

Schneider et al. (2007) reported that botulinum toxin injections proved effective in treating jaw tremor associated with dystonia in some cases.
Prevention and Self-Care
To reduce the likelihood of jaw twitching:
- Practice stress management techniques
- Maintain a balanced diet rich in magnesium and calcium
- Limit caffeine and alcohol intake
- Ensure adequate sleep and rest
- Practice good posture to reduce tension in jaw muscles
- Use a mouthguard if you grind your teeth at night
Conclusion
While jaw twitching can be annoying, it's often a benign condition that resolves on its own. However, persistent or severe symptoms should not be ignored. By understanding the potential causes and available treatment options, you can take proactive steps to manage jaw twitching and improve your overall oral health. If you're concerned about persistent jaw twitching, don't hesitate to consult with a healthcare professional for proper evaluation and personalized treatment recommendations.
