Teeth chattering is something most people experience at some point—usually during cold weather. But when it becomes frequent or occurs without an obvious cause, it can be a sign of something more serious. This article will explore the common and uncommon causes of teeth chattering, associated symptoms, and practical ways to stop it. Whether it’s temperature-related or due to an underlying condition, understanding the root cause is key to finding effective relief.

What Is Teeth Chattering?
Teeth chattering is an involuntary movement of the jaw and teeth, often causing a rhythmic clicking or clattering sound. While it’s typically harmless and short-lived, recurring episodes can be both uncomfortable and concerning.
Teeth chattering can happen in various scenarios—during stress, anxiety, fevers, or even neurological disorders. The key is to distinguish between occasional, harmless chattering and chronic episodes that may require medical evaluation.
Common Causes Of Teeth Chattering
Cold Temperatures
The most common and benign cause of teeth chattering is exposure to cold. When your body is cold, it shivers to generate heat—and that includes involuntary movements like teeth chattering.
Why it happens: Your muscles rapidly contract to increase body temperature. The jaw muscles, being no exception, cause the teeth to chatter as a side effect.
Fever and Illness
Fever, especially high fevers, can cause your teeth to chatter. This is often accompanied by chills and body aches.
Why it happens: When your body is fighting an infection, the immune response includes raising your internal temperature. This sudden change can trigger shivering and jaw tremors.
Stress and Anxiety
Emotional distress can lead to physical symptoms, including teeth chattering.
Why it happens: Stress triggers the “fight or flight” response, which can cause muscle tension, shivering, and even jaw clenching. In extreme cases, this may manifest as chattering.
Medication Side Effects
Some prescription drugs, particularly those affecting the nervous system or brain chemistry, can cause muscle spasms or tremors, including in the jaw.
Examples include:
- Antidepressants (SSRIs)
- Stimulants for ADHD
- Antipsychotics
If you suspect a medication is causing the issue, consult your healthcare provider before making any changes.
Neurological Disorders
In rare cases, teeth chattering can be a symptom of neurological conditions.
Examples include:
- Parkinson’s disease
- Epilepsy
- Tourette’s syndrome
These conditions often come with other signs, like tremors, involuntary movements, or speech difficulties. Persistent or worsening chattering should be evaluated by a neurologist.
Teeth Grinding (Bruxism)
Though not always accompanied by chattering, teeth grinding at night can cause similar jaw movements and sounds.
Signs of bruxism include:
- Worn-down teeth
- Jaw soreness
- Morning headaches
In some cases, bruxism evolves into jaw tremors or spasms during waking hours, mimicking chattering.
Symptoms That May Accompany Teeth Chattering
Understanding associated symptoms can help pinpoint the underlying cause.
- Chills or shivering (cold or fever-related)
- Muscle spasms
- Jaw stiffness or pain
- Sweating or anxiety
- Difficulty speaking or chewing
- Neurological signs like tremors in hands or limbs
The combination of symptoms gives vital clues. For example, chattering with a fever likely suggests an infection, whereas chattering with tremors might signal a neurological concern.
When To See A Doctor
Occasional teeth chattering due to cold weather isn’t concerning. However, see a healthcare provider if:
- It happens frequently without temperature changes
- You notice other symptoms like dizziness or coordination issues
- It disrupts your daily life or sleep
- You’re on medications that may be causing it
- It’s accompanied by intense anxiety or panic
Early diagnosis can prevent more serious complications, especially if a neurological or psychiatric condition is involved.
How To Stop Teeth Chattering
The treatment or management strategy depends on the underlying cause. Here are several ways to address it:
Keep Warm
If cold is the trigger, dress appropriately and use layers. Pay special attention to keeping your head and neck warm.
Tips:
- Use thermal wear
- Sip warm beverages
- Take warm showers or baths
Manage Stress and Anxiety
Mental health plays a large role in physical symptoms. If stress is causing your jaw to chatter, try:
- Deep breathing exercises
- Meditation and mindfulness
- Cognitive Behavioral Therapy (CBT)
- Journaling or talking to a counselor
Sometimes, mild anxiety medications may be prescribed if symptoms are severe.
Stay Hydrated and Eat Well
Dehydration or low blood sugar can cause shaky muscles or nervous reactions, including jaw tremors.
- Drink enough water
- Eat balanced meals throughout the day
- Avoid excessive caffeine and sugar
Use a Mouthguard
If bruxism or nighttime grinding is the cause, a custom mouthguard can protect your teeth and reduce jaw strain.
Consult a dentist to get fitted for the right type of mouthguard, especially if you’re grinding at night.
Review Medications
Check with your doctor if you suspect your medication is causing the issue. Alternatives or dosage changes may be considered to reduce side effects.
Never stop medication on your own—some medications require tapering or close monitoring when adjusting.
Treat Underlying Medical Conditions
If a neurological or systemic illness is the root cause, treating that condition should be the priority.
Depending on the diagnosis, treatments may include:
- Physical therapy
- Anti-seizure medications
- Dopamine treatments (for Parkinson’s)
- Behavioral therapy (for Tourette’s or anxiety-related causes)
Prevention Tips
- Stay warm in colder environments
- Reduce caffeine and stimulants
- Practice regular relaxation exercises
- Keep regular doctor visits if you have a neurological or psychiatric history
- Use protective dental devices if needed
Conclusion
Teeth chattering may seem like a minor inconvenience, but in some cases, it can signal an underlying health issue. By identifying the cause—whether it’s environmental, emotional, or medical—you can take steps to manage and prevent it. If the issue persists or worsens, don’t ignore it. Speak to a healthcare provider for a thorough evaluation and proper treatment plan.

FAQs
What is teeth chattering and is it normal?
Teeth chattering is the rapid, involuntary movement of the jaw that causes the teeth to hit each other, often making a clicking sound. It’s normal in cold environments but can also signal stress, fever, or medical conditions when it occurs frequently or without a clear reason.
Can stress or anxiety cause teeth chattering?
Yes. Stress and anxiety can trigger muscle tension and shivering responses in the body, including in the jaw, leading to teeth chattering. Managing stress through breathing exercises, meditation, or therapy can help reduce episodes.
Is teeth chattering a sign of Parkinson’s or a neurological issue?
It can be. While not always the case, persistent chattering without an obvious cause—especially when accompanied by other tremors or coordination problems—can be a symptom of neurological disorders like Parkinson’s disease or Tourette’s syndrome.
How do I know if my medication is causing my teeth to chatter?
If the chattering started after beginning a new medication or increasing a dose, it might be related. Some medications, especially those affecting the nervous system, can cause muscle spasms. Always consult your doctor before stopping or changing medications.
Can children experience teeth chattering?
Yes, children may chatter their teeth when they’re cold, scared, or during sleep. In most cases, it’s harmless. However, if it continues frequently or is accompanied by other symptoms, it’s best to consult a pediatrician.
