Tremors in the Lower Jaw: Causes, Symptoms, and Treatment

What are Tremors in the Lower Jaw?

Tremors in the lower jaw refer to involuntary shaking or twitching of the lower jaw. These tremors can affect speech, eating, and other jaw movements, and may be a sign of an underlying neurological disorder.

Causes of Tremors in the Lower Jaw

• Parkinson’s Disease. Tremors in the lower jaw are often seen in Parkinson’s disease as part of the overall tremor symptom.
• Essential Tremor. This condition may cause rhythmic shaking in various parts of the body, including the jaw.
• Cerebellar Disorders. Damage to the cerebellum can affect the motor control of the jaw, leading to tremors.
• Medication Side Effects. Certain medications may cause tremors, including those used to treat neurological conditions or anxiety.

Symptoms

• Involuntary shaking or twitching of the lower jaw, often noticeable while talking or eating.
• Difficulty chewing or speaking clearly due to tremors in the jaw.
• The tremors may be rhythmic and worsen during periods of stress or fatigue.

Treatment

• Medications. Beta-blockers, anticonvulsants, or Parkinson’s disease medications may be used to reduce jaw tremors.
• Botulinum Toxin Injections. In some cases, Botox injections can be used to help relax the muscles in the jaw and reduce tremors.
• Speech Therapy. Working with a speech therapist can help improve communication and swallowing skills for individuals with jaw tremors.
