Morning Headaches and Teeth Grinding: Is Bruxism the Cause?
Do you frequently wake up with a headache that seems to improve as the day goes on?
If so, nighttime teeth grinding—also known as bruxism—could be contributing to the problem.
Many people don't realize they grind or clench their teeth while sleeping. In fact, it's often a spouse, partner, or dentist who notices the signs first.
While teeth grinding is commonly associated with worn teeth and jaw pain, one of the most overlooked symptoms is waking up with headaches.
If you're new to the topic, our Comprehensive Guide to Night Guards explains how night guards work, who may benefit from them, and the different types available.
How Can Teeth Grinding Cause Morning Headaches?
When you grind or clench your teeth during sleep, the muscles responsible for chewing remain active for hours.
This prolonged muscle activity can create tension throughout the:
- Jaw
- Temples
- Sides of the head
- Neck
- Face
By morning, these muscles may be fatigued and inflamed, resulting in headache pain that often feels similar to a tension headache.
Many people describe the discomfort as:
- A dull ache around the temples
- Pressure on both sides of the head
- Tightness in the jaw and face
- Pain that improves as the day progresses
Severe clenching can place tremendous pressure on the teeth and jaw. If you're consistently damaging your appliance, you may also want to read Why Do I Keep Grinding Through My Night Guard?

Morning headaches caused by teeth grinding are often accompanied by other symptoms.
Common signs include:

- Teeth that feel sensitive

Why Does Teeth Grinding Happen?
Researchers believe several factors can contribute to bruxism.
Common causes include:
Stress and Anxiety
Stress is one of the most common triggers of nighttime grinding and clenching.
Sleep Disorders
Sleep apnea and other sleep-related breathing disorders have been associated with increased rates of bruxism.
Bite Misalignment
In some individuals, the way the teeth come together may contribute to grinding habits.
Lifestyle Factors
Caffeine, alcohol, tobacco, and certain medications may increase the likelihood of nighttime grinding.
A properly fitted Custom Night Guard can help protect teeth from the forces created by nighttime grinding and clenching.
What Do Bruxism Headaches Feel Like?
Not every headache is caused by teeth grinding.
Bruxism-related headaches often:
- Occur shortly after waking
- Feel centered around the temples
- Improve throughout the day
- Occur alongside jaw discomfort
Migraine headaches, on the other hand, may include:
- Nausea
- Light sensitivity
- Visual disturbances
- More severe pain
If you're unsure what's causing your headaches, it's important to discuss your symptoms with a healthcare professional.
Can a Night Guard Help?
A custom night guard does not cure bruxism.
However, it can help protect your teeth from the damaging effects of grinding and clenching.
A properly fitted custom night guard creates a protective barrier between the upper and lower teeth, helping reduce wear and prevent further damage.
Many people also report feeling less jaw fatigue and muscle soreness after consistently wearing a night guard.
