Jaw Clenching

It’s normal to clench your jaw on occasion throughout the day, especially if you’re anxious or tense. It’s not normal, however, to clench your jaw habitually and involuntarily while you are asleep.

How do I know if I am clenching my jaw at night?

Since jaw clenching (or bruxism) often occurs during sleep, it can be tricky to pinpoint. Fortunately, there are several tell-tale physical signs of jaw clenching and teeth grinding that you might notice upon waking:

Soreness or aching: You feel tenderness around your jaw joint, temples or even in your ears when you wake up.
Headaches: Frequent, dull tension headaches that seem to start in the temples.
Jaw tightness: A persistent feeling of stiffness, fatigue or tightness in your jaw muscles.
Dental issues: Loose, damaged, or flattened teeth, or worn tooth enamel (which your dentist will confirm).
Clicking jaw: Sometimes, severe bruxism can contribute to Temporomandibular Joint (TMJ) issues, causing a clicking, popping, or locking sensation when you move your jaw.
Partner reports: Your bed partner may hear the grinding sound while you sleep.

Jaw clenching causes

While the exact cause can vary, many oral health specialists point to emotional and psychological factors as the main drivers of bruxism:

Emotional stress: Bruxism often affects people experiencing nervous tension from anger, frustration, pain or high-stress periods.
Personality types: Those with aggressive, hurried or overly competitive tendencies may be more susceptible.
Neurotransmitters: There is some evidence suggesting that an imbalance in certain brain neurotransmitters could play a role in some individuals.
Medications: Certain prescription medications, such as the antidepressants fluoxetine and paroxetine, can potentially cause bruxism as a side effect.

At-home remedies for jaw clenching

If you suspect you're a night clencher, implementing stress-reduction techniques can be a powerful first line of defense. These practices promote muscle relaxation and can be performed in the comfort of your home:

Stress reduction: Regular practice of yoga, deep breathing exercises or meditation can significantly reduce overall tension. Twenty minutes of cardiovascular exercise during the day could reduce overall stress and improve sleep.
Nightly routine: Try applying a warm compress or a heating pad to your jaw muscles for about 15 minutes before bed to soothe and relax the area. If your neck and shoulders are tense, you may also add a warm compress to those areas.
Jaw stretches: Gently stretching your jaw muscles during the day can help relieve chronic tightness. Consult your doctor or dentist for safe, effective stretches.
Mindfulness: Practice being aware of when you are clenching during the day (e.g., while driving, working out, or focusing intensely) and consciously relax your jaw. Tip: Place your tongue between your top and bottom front teeth to prevent clenching.

Treatment for jaw clenching

If at-home remedies aren't enough, it's essential to talk to your dentist and primary care physician. They can provide personalized guidance and share the most suitable treatment options for you:

Dental night guard: Should your dentist notice signs of bruxism during an exam, they may suggest a custom-made night guard. Worn while you sleep, this device does not stop the clenching, but it protects your teeth from damage and distributes the pressure evenly.
Managing underlying causes: It would be helpful to discuss your stress and anxiety levels with your doctor. If bruxism is a side effect of medication, they may suggest an alternative. Cognitive Behavioral Therapy (CBT) may also be recommended to address the underlying psychological factors.
Physical therapy: Your doctor may prescribe physical therapy. This would help you release jaw tension, correct your posture, and learn exercises and stretches.
Muscle relaxants: Your doctor may prescribe a muscle relaxant to be taken before bed to help reduce the intensity of jaw clenching at night.

If you know or suspect that you are clenching your jaw at night, taking these steps and speaking with a professional is crucial to protecting your teeth and relieving chronic pain.
