Most people who grind their teeth have no idea they’re doing it.

They wake up with a sore jaw. Maybe a headache that doesn’t quite make sense. Their teeth suddenly feel sensitive to cold drinks. Someone mentions hearing strange grinding noises during the night. And honestly, most people brush it off for months before connecting the dots. 

But teeth grinding can quietly cause a surprising amount of damage over time.

Dentists call it bruxism — and it’s one of those problems that tends to creep up slowly. People around Bayswater often assume their jaw tension is just stress, poor sleep, or “getting older”. Fair enough. The symptoms don’t always seem obviously dental at first.

The problem is that untreated grinding can wear teeth down, crack fillings, trigger headaches, and place serious pressure on the jaw joint.

So, What Exactly Is Bruxism?

Bruxism is the medical term for grinding or clenching your teeth — usually during sleep and usually without realising it.

Some people grind their teeth side to side, which slowly wears the enamel down. Others clench tightly for long periods during the night. Both can put enormous pressure on the teeth and jaw muscles.

And unlike chewing, which happens in short bursts, grinding can continue for hours while you’re asleep.

That’s why even people with otherwise healthy teeth can end up with worn enamel, cracked fillings, or constant jaw soreness over time.

Daytime clenching is common too. A lot of people tense their jaw while working, driving, studying, or concentrating without even noticing.

Why Do People Grind Their Teeth?

Honestly, there isn’t always one simple reason.

Bruxism usually happens because of a combination of factors rather than one single cause.

Stress and Anxiety

This is probably the biggest trigger dentists see.

People often grind more during stressful periods — work pressure, financial stress, poor sleep, family issues, exam periods. Sometimes the body holds tension in the jaw without people realising it.

And because grinding happens during sleep, many people don’t connect their stress levels to their dental symptoms straight away.

According to the Australian Dental Association, stress-related clenching and grinding is very common in adults.

Sleep Problems

Teeth grinding is also linked to sleep disorders, especially sleep apnoea.

In some cases, the body responds to interrupted breathing during sleep by clenching or grinding the jaw muscles. Dentists will often ask about snoring, poor sleep quality, or constant fatigue when patients report grinding symptoms.

For more information about sleep apnoea symptoms, Healthdirect Australia has helpful resources explaining the condition.

Caffeine and Alcohol

Late-night coffee, energy drinks, alcohol, and poor sleep habits can all make grinding worse for some people.

That doesn’t mean everyone with an iced latte habit is damaging their teeth. But if jaw pain and poor sleep are becoming regular issues, it’s worth paying attention to patterns.

Certain Medications

Some antidepressants and anxiety medications can contribute to teeth grinding as a side effect.

If symptoms started after changing medication, it’s worth mentioning during your dental appointment or GP visit.

Genetics

Grinding does tend to run in families. If your parents ground their teeth, there’s a decent chance you might too.

Signs You Might Be Grinding Your Teeth

Because bruxism mostly happens during sleep, the signs are often indirect.

Here are some of the most common ones dentists see around Bayswater:

• Morning jaw soreness or tightness
• Tension headaches around the temples
• Sensitive teeth, especially to cold drinks
• Teeth looking flatter or shorter
• Clicking or aching in the jaw joint
• Earache without an ear infection
• Broken fillings or chipped teeth
• Partners hearing grinding sounds at night
• Cheek biting or scalloped tongue edges

Most people don’t experience every symptom.

But even two or three together can point towards grinding.

And honestly, many people ignore it longer than they should.

What Happens If You Ignore Teeth Grinding?

This is where things can become expensive.

Enamel doesn’t grow back once it wears away. Grinding slowly removes the protective outer layer of the teeth, leaving the more sensitive inner structure underneath exposed.

Over time, untreated bruxism can lead to:

Cracked Teeth

Constant pressure can create tiny fractures in teeth. Some stay minor. Others eventually require crowns or root canal treatment.

Tooth Sensitivity

As enamel thins, cold drinks, ice cream, or even cold air can suddenly become painful.

Damage to Dental Work

Crowns, veneers, implants, and fillings can all be damaged by heavy grinding forces.

TMJ Problems

The jaw joint sits close to the ears and facial muscles. Long-term clenching can lead to jaw clicking, headaches, facial pain, and difficulty opening the mouth properly.

Gum Recession

Grinding pressure can sometimes contribute to gum recession, exposing tooth roots and increasing sensitivity.

None of this is meant to sound alarming. Some people grind mildly for years without major issues.

But the earlier it’s picked up, the easier — and usually cheaper — it is to manage.

Can Children Grind Their Teeth?

Yes. And it worries parents more often than you’d think.

Teeth grinding is fairly common in children, especially between ages 3–6 and again during early adolescence.

Most cases settle naturally as children grow.

Still, if your child regularly complains about jaw discomfort, headaches, or you can visibly see tooth wear, it’s worth bringing up during a dental check-up.

Better Health Channel also notes that childhood teeth grinding is relatively common and often temporary.

What Does a Dentist Actually Do for Bruxism?

The first step is identifying how severe the grinding is.

A dentist will usually check for:

• Tooth wear
• Cracks or fractures
• Muscle tenderness
• Jaw joint strain
• Signs of clenching
• Existing dental work damage

If grinding is confirmed, the most common treatment is a custom night guard.

Are Custom Night Guards Better Than Pharmacy Ones?

Usually, yes.

A lot of people around Bayswater try the boil-and-bite versions from the chemist first. Fair enough — they’re cheaper upfront.

But many are bulky, uncomfortable, and don’t fit the bite properly.

A professionally made night guard is designed from detailed impressions or digital scans of your teeth. The fit tends to feel much more natural, which makes people more likely to actually wear it consistently.

And that’s important.

Because even the best night guard won’t help much if it stays in a bathroom drawer after three nights.

At Aura Dentists, custom night guards are designed to comfortably protect the teeth while reducing strain on the jaw muscles and joints.

A Lot of People Don’t Realise Jaw Pain Can Be Dental

This catches people off guard all the time.

Patients often assume their headaches come from stress, posture, screen time, or poor sleep. And sometimes that’s partly true.

But chronic jaw tension and teeth grinding can absolutely contribute to:

• Morning headaches
• Facial soreness
• Neck tension
• Tooth pain
• Ear discomfort
• Trouble chewing

A lot of patients around Bayswater mention these symptoms almost casually during a check-up — as though jaw pain isn’t really something a dentist deals with.

It absolutely is.

When Should You Book a Dental Appointment?

It’s worth getting checked if:

• You wake up with jaw pain most mornings
• Your teeth are becoming sensitive
• You’ve chipped or cracked teeth unexpectedly
• Someone hears you grinding during sleep
• Your headaches are becoming frequent
• Existing crowns or fillings keep breaking
• Your jaw clicks or locks

If you’re in Bayswater or nearby eastern suburbs and this sounds familiar, a dental check-up is a good place to start.

And if you’re dealing with severe jaw pain or a cracked tooth right now, emergency dental appointments may be needed sooner rather than later.

Small Things That Can Help in the Meantime

While a night guard is usually the most effective protection, a few simple habits can help reduce symptoms:

• Notice daytime clenching habits
• Avoid excessive caffeine late at night
• Improve sleep routines where possible
• Use warm compresses for jaw tension
• Avoid very hard or chewy foods during flare-ups
• Try keeping your teeth slightly apart while resting

None of these replace proper dental assessment. But they can help ease some of the muscle strain temporarily.

The Bottom Line

Teeth grinding is one of those problems that people often live with quietly for years.

The symptoms seem disconnected at first. Jaw pain. Headaches. Sensitive teeth. Broken fillings. Poor sleep.

Most people don’t immediately think: Maybe I’m grinding my teeth at night.

But catching bruxism early can prevent a lot of long-term damage — not just to the teeth, but to the jaw joint and surrounding muscles too.

And honestly, treatment is usually far simpler when the problem is identified early rather than after years of wear.

If something in this article sounds familiar, it’s probably worth bringing up at your next dental check-up.
