If you’ve ever wondered, “Why do I grind my teeth at night?”, you’re not alone. This condition, commonly known as bruxism, affects millions of people and often goes unnoticed until symptoms like jaw pain, tooth damage, or morning headaches start showing up.
At 65 Broadway Dental, we see many patients dealing with the effects of nighttime teeth grinding, and the good news is, it’s highly treatable. Let’s explore what causes this habit, how it affects your health, and, most importantly, what you can do to stop it.
What Is Teeth Grinding (Bruxism)?
Teeth grinding, or bruxism, is when you unconsciously clench or grind your teeth. While some people do this during the day (called awake bruxism), many don’t realize they’re grinding at night, until a dentist points it out or the symptoms start piling up.
Signs of nighttime teeth grinding may include:
- Sore jaw in the morning
- Worn-down teeth
- Clicking or popping in your jaw
- Headaches around the temples
- Your partner hears grinding sounds while you sleep
Think of it like your body being tense even when you’re asleep. But the good news? Once you know what’s causing it, you can take steps to fix it.
Why Do I Grind My Teeth at Night? (Main Causes)
There isn’t just one reason behind teeth grinding. It can be caused by a mix of physical, psychological, and even genetic factors. Let’s break it down.
1. Stress and Anxiety
This is by far the most common reason. When your brain doesn’t get a break, even during sleep, it can turn to grinding as a physical outlet for stress. That’s why stress-related teeth grinding often hits during high-pressure times like work deadlines, breakups, or big life changes.
2. Sleep Disorders
Conditions like sleep apnea, snoring, or even chronic insomnia have been linked to bruxism. Your body might grind its teeth in response to airway blockages or interrupted sleep.
If you grind your teeth and feel extremely tired during the day, a sleep study might be the next step.
3. Bite or Alignment Issues (Malocclusion)
Sometimes, your upper and lower teeth don’t align properly. This “bad bite” creates tension in the jaw and causes your mouth to keep adjusting during sleep, often through grinding.
4. Lifestyle Habits
Love your nightly coffee or that glass of wine before bed? Bad news: caffeine, alcohol, and tobacco all increase your chances of grinding. They stimulate the nervous system and interfere with your body’s ability to fully relax.
Certain medications, especially some antidepressants or ADHD meds, can also be triggers.
5. Genetics
If your parents or siblings grind their teeth, there’s a good chance you might too. Bruxism can run in families, even if everyone’s triggers are different.
What Happens If You Don’t Treat Nighttime Teeth Grinding?
Bruxism isn’t just annoying; it can be damaging. If left untreated, it can lead to serious dental and health issues over time.
1. Tooth Damage
Constant grinding wears down your enamel. Over time, your teeth may chip, crack, or become extremely sensitive. You might even need crowns or root canals to fix the damage.
2. Jaw Pain and TMJ Disorders
Your jaw is working overtime every night. This leads to tightness, pain, and in many cases, TMJ disorders (issues with the temporomandibular joint).
Symptoms of TMJ include:
- Popping or clicking when you open your mouth
- Difficulty chewing
- Pain around your ears or temples
3. Headaches and Earaches
The pressure from grinding affects the muscles in your face, neck, and head, causing tension headaches and even earaches (even though your ears are fine).
4. Poor Sleep Quality
Teeth grinding can disrupt your REM sleep cycle. You may wake up multiple times without realizing it, and over time, this leads to fatigue, irritability, and poor focus during the day.
How Can You Stop Grinding Your Teeth at Night?
The good news: There are solutions. Here’s what works (and how to start).
1. Night Guards or Splints
One of the easiest and most effective tools is a custom night guard. It’s a soft or hard appliance you wear over your teeth to prevent direct grinding.
Think of it as a cushion between your upper and lower jaw. Over-the-counter options exist, but custom-made guards from a dentist are much more effective and comfortable.
2. Stress Management Techniques
If stress is your trigger, learning to manage it can make a huge difference. You could try:
- Meditation or deep breathing before bed
- Keeping a journal to unload thoughts
- Talking to a therapist
- Exercise to release built-up tension
Many patients see results just by making relaxation a bedtime habit.
3. Treating Underlying Sleep Disorders
If a sleep disorder like sleep apnea is behind your bruxism, you’ll need to address that first. Treatments might include:
- A CPAP machine
- Oral appliances to keep airways open
- Adjusting your sleeping position
Ask your doctor or dentist about getting a sleep study done.
4. Dental Corrections
If your bite is misaligned, your dentist may suggest:
- Orthodontic treatment (like braces or aligners)
- Reshaping certain teeth
- Using crowns to balance your bite
Correcting the structure often leads to less grinding long term.
5. Lifestyle Changes
Small habits can make a big impact. Start with:
- Cutting back on caffeine after 2 PM
- Limiting alcohol and smoking, especially at night
- Setting a consistent sleep schedule
- Avoiding screen time before bed
You’ll likely feel more rested and notice fewer symptoms.
When Should You See a Dentist or Specialist?
If you’re waking up with jaw pain, tooth sensitivity, or your partner complains about loud grinding sounds, you should definitely talk to a dentist.
They’ll:
- Examine your teeth for signs of wear
- Recommend a night guard
- Refer you to a sleep specialist if needed
Don’t wait until things get worse. Early intervention saves you time, money, and a lot of pain later on.

FAQs
1. Is it normal to grind your teeth at night?
It’s more common than you might think! Many people grind their teeth at night without even realizing it. While occasional grinding isn’t usually harmful, doing it regularly (a condition called bruxism) can lead to serious dental issues like worn teeth, jaw pain, and sleep problems. So if you notice signs, it’s a good idea to talk to your dentist.
2. How can I tell if I grind my teeth in my sleep?
Most people don’t realize they’re grinding unless a partner hears it or their dentist spots the signs. Common symptoms include:
- Sore jaw or temples in the morning
- Headaches after waking
- Worn, flattened, or chipped teeth
- Clicking sounds in your jaw
- Poor sleep quality
3. What is the best treatment for nighttime teeth grinding?
The most common and effective treatment is wearing a custom night guard, which protects your teeth from further damage. Other treatments include managing stress, correcting bite issues, or treating underlying conditions like sleep apnea. Your dentist can help you choose the best plan based on what’s causing your grinding.
4. Can stress really cause me to grind my teeth?
Absolutely. Stress and anxiety are the top triggers for nighttime teeth grinding. If you’re clenching your jaw during the day or experiencing high stress levels, it can carry over into your sleep. Managing stress through relaxation techniques, therapy, or better sleep hygiene can significantly help.
5. Will grinding my teeth go away on its own?
Sometimes, especially if it’s caused by a short-term stressor. But if it continues over time, it often needs intervention to avoid long-term damage. Don’t wait for it to go away; early treatment can save you from bigger dental and health problems down the road.
