You go to bed feeling fine, but wake up with a sore jaw, headache, or sensitive teeth. Sometimes, your partner may even tell you that you were making a grinding sound during sleep.
This problem is known as teeth grinding at night, or sleep bruxism. It happens when you clench, grind, or move your teeth against each other while sleeping. Most people do not know they are doing it because it happens without conscious control.
It is also more common than many people think. A 2024 systematic review and meta-analysis estimated the global prevalence of sleep bruxism at around 21%, although rates differ depending on how the condition is diagnosed.
Occasional grinding may not create serious problems. However, frequent teeth grinding while sleeping can slowly damage teeth, strain the jaw muscles, and affect your comfort.

So, what causes teeth grinding at night?
There is not always one clear reason. Bruxism can develop due to several factors working together. Stress is certainly one of them, but it is not the only possible trigger.
Some common factors include:
- Stress, anxiety, or emotional pressure
- Poor-quality or disturbed sleep
- Sleep disorders
- Smoking
- Drinking alcohol frequently
- High caffeine intake
- Certain medications
- Family history of bruxism
- Other health or sleep-related conditions
Cleveland Clinic notes that stress and anxiety are common risk factors. Lifestyle habits can matter too. People who smoke, drink alcohol, or consume high amounts of caffeine may have a greater risk of grinding their teeth.
For example, imagine someone who drinks several cups of coffee during a stressful workday and then has another coffee late in the evening. They may already be carrying tension in their jaw. Disturbed sleep can add another factor to the problem.
This does not mean coffee alone causes bruxism. Usually, there is a bigger picture to consider.
Can Stress Really Make You Grind Your Teeth?
Yes, stress can play an important role.
You may notice yourself clenching your jaw while working, driving, concentrating, or dealing with a difficult situation. That tension can sometimes continue during sleep.
The Mayo Clinic also explains that people may grind or clench their teeth when they feel tense, worried, or under pressure.
The problem is that nighttime grinding is harder to control because you are asleep.
That is why simply telling yourself, “I will stop grinding tonight,” usually does not work.
Could a Sleep Problem Be Behind the Grinding?
Sometimes.
Sleep bruxism can occur alongside sleep disorders such as obstructive sleep apnea. However, researchers are still studying exactly how these conditions are connected.
A 2026 umbrella review found that obstructive sleep apnea and sleep bruxism often occur together, but current evidence does not prove that one directly causes the other.
Tell your healthcare provider if your grinding happens along with symptoms such as loud snoring, gasping during sleep, frequent waking, or strong daytime sleepiness. These symptoms may need further evaluation.
Signs You May Be Grinding Your Teeth
Because grinding happens during sleep, the first signs often appear the next morning.
| Possible Sign | What You May Notice |
|---|---|
| Jaw tension | Tight or tired jaw after waking |
| Headaches | Dull morning headache near the temples |
| Tooth wear | Teeth may appear flatter or shorter |
| Sensitivity | Discomfort with hot or cold foods |
| Cracked teeth | Small cracks or damaged dental work |
| Facial discomfort | Soreness around the cheeks or jaw |
| Grinding sounds | A partner may hear grinding during sleep |
Bruxism may also contribute to tooth erosion, cracked teeth, facial pain, and temporomandibular joint problems when it continues for a long time.

People searching for how to stop grinding teeth at night often hope there is one product that can solve the problem immediately.
Unfortunately, treatment is not quite that simple.
The first step is finding possible triggers and protecting the teeth from further damage.
Use a Custom Night Guard
A dentist may recommend a dental night guard, also called an occlusal splint.
The guard creates a protective layer between your upper and lower teeth. This can reduce direct tooth-to-tooth contact and help protect enamel and dental restorations from grinding forces.
The Cleveland Clinic explains that a dentist-made custom night guard offers a close and comfortable fit because it is created specifically for the patient’s mouth.
It is important to understand that a night guard mainly protects the teeth. It may not remove the underlying reason why you grind.
Over-the-counter mouth guards are also available in pharmacies and stores. However, fit and comfort can vary. A poorly fitting guard may feel bulky or uncomfortable, so speak with your dentist before using one regularly.
Reduce Evening Triggers
Small lifestyle changes may also help reduce risk factors.
Try cutting down on caffeine later in the day, especially coffee, strong tea, energy drinks, and some sodas. Reducing smoking and heavy alcohol use may also help.
One large review found consistent associations between bruxism and factors including caffeine, alcohol, tobacco, and some psychotropic medications.
Never stop prescription medicine on your own because you suspect it is causing grinding. Speak with the healthcare professional who prescribed it.
Give Your Jaw Time to Relax
A simple bedtime routine may reduce tension before sleep.
You can:
- Take a warm shower before bed.
- Place a warm compress over tight jaw muscles.
- Gently massage your jaw and temples.
- Avoid chewing gum for long periods.
- Practice slow breathing or relaxation exercises.
- Keep a regular sleep schedule.
These habits will not automatically cure bruxism, but they can be useful when stress and muscle tension are part of the problem.
How Do You Prevent Grinding Your Teeth at Night?
Patients often ask, “How do you prevent grinding your teeth at night if you cannot control what happens while sleeping?”
Complete prevention is not always possible.
Instead, focus on reducing triggers, protecting your teeth, and treating related problems.
Regular dental examinations are especially important. A dentist may notice unusual tooth wear, tiny cracks, damaged fillings, or changes in your bite before you realize you are grinding.
Cleveland Clinic recommends regular dental checkups as one way to identify and manage damage related to bruxism before it becomes worse.
What Does Bruxism Treatment Include?
The right bruxism treatment depends on your symptoms and possible causes.
Treatment may include a custom night guard, stress management, lifestyle changes, better sleep habits, treatment of an underlying sleep disorder, or management of jaw discomfort.
In more serious situations, healthcare professionals may consider additional treatments. Some patients may receive short-term medication or, in selected severe cases, botulinum toxin injections to relax overactive jaw muscles. These options are not suitable or necessary for everyone and should only be considered after professional evaluation.
Research also shows that occlusal appliances are commonly used for managing bruxism and protecting teeth, although evidence for many other treatment methods remains less certain.
When Should You See a Dentist?
Do not wait until a tooth breaks.
Schedule a dental examination if you regularly experience morning jaw pain, headaches, unexplained tooth sensitivity, worn teeth, chipped teeth, or damaged fillings and crowns.
You should also mention it if someone regularly hears you grinding during sleep.
Finding the problem early can make it much easier to protect your natural teeth.
