Can Your Dentist Tell If You Grind Your Teeth?

Signs, Diagnosis & Solutions for Bruxism

That split-second ache in your jaw when you wake up. The sudden headaches in the morning. Maybe your partner has whispered that you sound like a coffee grinder in your sleep. If you’re reading this, you’re probably wondering: Can a dentist really tell if you grind your teeth—even if you don’t notice it yourself?

First, let’s help you feel better. Yes, a dentist can almost always spot the signs of teeth grinding, even when you don’t know it’s happening. In fact, finding bruxism (which means grinding and clenching your teeth) is super important for keeping your mouth healthy and pain-free.

But how do dentists know? What should you look out for yourself, and what happens if grinding isn’t helped? Let’s walk through the story of teeth grinding, from the quiet signs to easy fixes—so you feel good about keeping your smile safe.

Why Teeth Grinding Is Hard to Notice

Picture this: you close your eyes, fall asleep, and your body relaxes. But somewhere between light sleep and deep dreaming, your jaws start pressing together. Hard.

Most people with bruxism don’t know it’s happening. You could be grinding while you sleep, at your desk, or even sitting in traffic. Experts say that up to 90% of people with sleep bruxism—that’s the kind that happens at night—don’t know about it until a dentist or someone else tells them.

Bruxism isn’t rare. About 8-10% of adults grind their teeth at night, and up to 30% of adults may clench their jaws during the day, especially when stressed. For kids, teeth grinding happens for about 14-20%, but usually goes away as they get older.

You might miss the signs because:

• Grinding usually happens during sleep.
• The signs build slowly—kind of like how water slowly changes a rock’s shape.
• Early damage doesn’t always hurt.

Let’s check out how your dentist can catch these sneaky habits, even before you know something’s wrong.

How Dentists Find Bruxism at Your Checkup

You might think your dentist is only about “cavities,” but they’re also like investigators looking for early warning signs in your mouth.

Why dentists are good at noticing bruxism:

• They check your teeth, gums, and jaws regularly.
• They see tiny clues that others might miss.
• They know the patterns of wear that you wouldn’t see in your bathroom mirror.
• They connect the dots—even if you haven’t—like jaw soreness and cracked fillings.

Dentists look at everything: your health history, what you tell them, how your teeth bite together, and anything else that seems important.

You’ll hear dentists use words like attrition (teeth wearing down), abfraction (V-shaped notches), or hypertrophy (big muscles). Don’t worry. These are just words for the problems that come from grinding and clenching.

But what does this look like for real? Let’s get close to the usual signs.

Signs Dentists Check For

Not sure if you’re grinding? Here’s what your dentist might spot—think of it like reading a map of clues in your mouth.

A. Signs on Your Teeth: Wear and Damage

Flat, Chipped, or Broken Teeth

Grinding acts like sandpaper in your mouth all night. Over time, your teeth might get flat, feel sharp, or start to chip. Your pointy “eye teeth” might look more square.

Thinner or Worn Enamel

The hard white outside of your teeth (enamel) can get thin from grinding. As it wears down, the yellow layer under it (dentin) might start to show.

Cracks & Broken Dental Work

If your fillings, crowns, or even veneers keep breaking for no obvious reason, it’s often from grinding.

Abfraction Lesions

Grinding can make small V-shaped bites near your gum line, called abfractions.

More Sensitive Teeth

When enamel goes away, hot, cold, sweet, or sour foods might suddenly make your teeth hurt.

B. Gums and Soft Tissue Signs

Gum Recession and Bone Loss

While other things can make your gums move back, grinding can speed up bone loss around your teeth.

Tongue or Cheek Marks

Noticed wavy lines on the edge of your tongue or red spots on your cheeks? Your jaws might be pressing or biting there without you knowing.

C. Jaw & Muscle Signs

Big or Sore Jaw Muscles

Your main chewing muscle can get bigger, like a muscle on your arm, after years of clenching. You might notice your jaw feels tight, sore, or tired.

Morning Headaches or Ear Pain

These aren’t always about being sick. Lots of daytime headaches or that “tight band” feeling can come from hard-working jaw muscles.

Jaw That Won’t Open Fully

Find it tough to open wide at the dentist, or hear clicking in your jaw? Grinding puts pressure on the TMJ (temporo-mandibular joint), and sometimes makes it stiff or noisy.

The Diagnosis Steps: History, X-rays, and More

A great dentist doesn’t just look—they listen and ask smart questions. Figuring out bruxism is like being a detective. Here’s what usually happens:

1. Asking Questions

• “Do you ever wake up with a sore jaw or headache?”
• “Has anyone said your jaw makes noise?”
• “Any gritty feeling, pain, or trouble with dental work?”
• “Are you under more stress lately?”
• “Does your partner notice you grinding or making sounds at night?”

2. Examining Your Mouth and Face

• Checking for wear, cracks, or teeth that look flat or different.
• Looking at fillings and crowns—are they broken or loose for no clear reason?
• Pressing softly on jaw muscles to see if they’re sore.
• Seeing how wide you open, or if your jaw makes noise.

3. Dental X-rays

X-rays catch things we can’t see:

• Hidden cracks
• Early bone loss
• Root or nerve problems
• Issues under a crown or filling

4. Extra Tests (If Needed)

If the problems are big, or your case is tricky, you might need:

• Sleep studies: To check grinding and possible sleep apnea.
• Muscle tests: To measure tension in your jaws.
• Special dentist or doctor visits if you need more advice.

But most of the time, your dentist’s sharp eye and careful check are enough.

Types of Bruxism: Awake vs. Sleep

You might wonder: is all grinding the same? Not exactly.

Awake Bruxism:

• Usually happens during the day.
• Linked to stress, worry, focus, or a lot of caffeine.
• You might notice yourself clenching while working or driving.

Sleep Bruxism:

• Happens without you knowing, while you’re asleep.
• Often goes unnoticed unless someone else hears it, or you wake up sore.
• Can be linked to sleep problems, acid reflux, or family history.

Why does this matter? The kind you have helps your dentist decide what’s best for you.

Your Choices for Help and Repair: What to Do

Let’s split this into what you can try at home, and when you should see a dentist.

What You Can Try at Home

Lower Stress and Worry

• Try deep breathing, meditation, or easy stretching.
• Talk about seeing a counselor or therapist if you feel really anxious.

Change a Few Habits

• Drink less coffee or soda after lunch.
• Try to avoid too much alcohol or cigarettes, which can make grinding worse.

Teach Your Jaw to Relax

• Remind yourself to keep your teeth a bit apart except when eating.
• Use a warm towel on your jaw if it’s tired before bed.

Think About Magnesium or Diet Changes

• Ask your doctor if magnesium might help your muscles chill out.

Keep Track

• Write down when your jaw is sore or teeth feel sensitive, to see if there’s a pattern.

When to See a Dentist

You should make an appointment if:

• Your jaw hurts, especially in the morning.
• Teeth look flat, chipped, or are more sensitive than before.
• Fillings, crowns, or dentures keep breaking for no reason.
• Your partner hears you grinding at night.
• You keep getting headaches or sore ears.

Your dentist might suggest things like:

Made-Just-For-You Night Guards or Splints

These are fitted to your mouth and act like a shield to keep teeth safe. They help your jaw muscles rest and protect your teeth.

(See how night guards are made at our night guard dental lab.)

Training and Therapy

For daytime clenching, things like reminders or biofeedback can help you stop.

Dealing With the Cause

If grinding is from sleep apnea or other health problems, a sleep doctor might suggest a mask or special dental piece. Sometimes fixing your bite or treating reflux helps.

Repairing Damaged Teeth

• Fillings, crowns, or veneers can fix broken or worn teeth.
• For tough cases, a crown and bridge lab can help bring back your smile and how your teeth work.

Medicines (Only Sometimes)

• Muscle relaxers used for a short time, if pain is really bad.
• Botox shots—sometimes used if nothing else works.

Who Gets This Problem? Are You at Risk?

Short answer: just about anyone can get it. But these things make it more likely:

• Stressful life: Extra worry or busy work/home life makes more grinding.
• Family history: If others in your family grind, you might too.
• Some medicines: A few depression or ADHD drugs may cause grinding.
• Coffee, alcohol, or smoking
• Sleep problems: People with sleep apnea or snoring are more likely to grind.
• Kids: Especially while growing, but it often stops as they get older.

People with a lot of dental work or missing teeth might push too hard with the teeth they have.

What If You Ignore Teeth Grinding?

You might wonder, “Is this really a big deal?” Here’s what tends to happen:

Teeth Get Damaged:

Bruxism can wear your teeth down 10 times faster than regular chewing. This can make your teeth hurt, crack, or even lead to losing a tooth.

Broken Fillings and Crowns:

It gets expensive to keep fixing dental work—and the reason isn’t fixed yet.

TMJ Problems:

Grinding makes TMJ (jaw joint) issues worse. You might have pain, clicking, or trouble talking or eating.

Daily Discomfort:

Frequent headaches, sore face muscles, neck and shoulder pain can all happen.

Gum and Bone Issues:

Over the years, grinding can cause gum loss and bone loss in your jaw.

Lower Quality of Life:

It’s tough to sleep, eat, or smile if your mouth always hurts.

When Should You Call the Dentist?

Don’t wait for things to get really bad, especially when catching it early can stop years of trouble.

Call your dentist if you:

• Notice teeth getting flatter or shorter.
• Get jaw pain or steady headaches.
• Have fillings or crowns that keep breaking.
• Wake up with sore face muscles.
• Feel a gritty, sensitive feeling in your teeth.
• Have a partner who’s caught you grinding.

Not sure if it’s a big deal? Remember: dentists catch things early, so regular check-ups are your best bet.

Frequently Asked Questions

Can I tell if I’m grinding my teeth without a dentist?

Some people notice jaw pain, tooth sensitivity, or teeth looking “shorter.” But many don’t know until a dentist checks.

Do I need a night guard if I grind my teeth?

If it’s causing damage, pain, or discomfort, most dentists say a custom guard is a good idea. It can make a big difference.

Can children outgrow teeth grinding?

Yes—most kids stop after a few years. But if there’s pain or damage, it’s smart to check in with the dentist.

Does bruxism always need treatment?

No, not always. If grinding isn’t hurting anything, your dentist might just watch for changes. If there is damage or regular pain, treatment is best.

Can new dental work be hurt by grinding?

Yes. Grinding wears down fillings, bridges, and crowns. Some special labs, like a dental ceramics lab, use stronger materials for grinders.
