What Is Teeth Grinding (Bruxism)?

Bruxism is the medical term for grinding, gnashing, or clenching your teeth outside of normal chewing. It most commonly happens during sleep, which means many people are unaware they do it at all until a partner mentions the noise, or Dr Pham points out the wear pattern at a routine check-up at our Parap clinic. Some people also clench during the day, often without realising it — under stress, while concentrating, or while driving.

Grinding generates forces on the teeth that are considerably higher than normal biting, and because it can continue for hours during sleep, the cumulative load on teeth, jaw muscles, and the jaw joint adds up quickly. Left unmanaged over months or years, it can contribute to worn tooth surfaces, jaw discomfort, and disturbed sleep for both the person grinding and anyone sleeping nearby.

There is rarely a single cause. Stress and muscle tension are commonly involved, as are sleep patterns, caffeine and alcohol intake, and — for some people — the way the upper and lower teeth meet. Grinding can also appear or worsen during particularly busy or stressful periods of life, which is why some patients notice it comes and goes rather than staying constant. Dr Pham will ask about these factors as part of a bruxism assessment at our Parap clinic, since understanding the likely contributors helps guide the right management approach alongside a night guard.

Signs & Symptoms of Teeth Grinding

Because bruxism so often happens overnight, the symptoms are frequently the first clue rather than the act of grinding itself:

Jaw pain, soreness, or tightness, especially first thing in the morning
Headaches concentrated around the temples or forehead
Worn, flattened, or shortened-looking teeth
Increased sensitivity to hot, cold, or sweet foods as enamel thins
Cracked, chipped, or fractured teeth or restorations with no obvious cause
Disturbed or unrefreshing sleep
A partner or family member reporting they can hear you grinding at night

If several of these sound familiar — particularly morning jaw soreness combined with visible tooth wear — it is worth having Dr Pham take a look at your Parap check-up.

Custom Night Guards (Occlusal Splints)

A custom night guard, also known as an occlusal splint, is a close-fitting acrylic appliance made specifically for your teeth and worn while you sleep. Rather than an off-the-shelf or boil-and-bite product, it is made from a precise impression or digital scan of your teeth taken at our Parap clinic, then fabricated by our dental laboratory to fit snugly over the biting surfaces.

Because it is custom-made, the guard sits securely without excess bulk, is comfortable enough to wear for a full night, and does not interfere with normal breathing. It is generally more comfortable and more durable over time than a generic guard purchased from a chemist, which tends to be looser, thicker, and more prone to distorting with wear.

Night guards can be made in different thicknesses and materials depending on how heavily you grind or clench — a lighter guard is often suitable for mild clenching, while a firmer, more robust design may be recommended for heavier grinders or where existing dental work needs additional protection. Dr Pham selects the design based on what he observes during your examination at our Parap clinic, rather than a one-size-fits-all approach.

How a Custom Night Guard Helps

A night guard does not stop the grinding habit itself, but it changes what the grinding acts on and can meaningfully reduce its impact:

Provides a protective barrier between the upper and lower teeth, helping reduce further tooth wear from grinding
Can help ease jaw muscle tension and reduce morning soreness and headaches for some patients
Helps protect existing dental work — fillings, crowns, and veneers — from premature wear and cracking
Spreads grinding forces more evenly across the jaw rather than concentrating them on a few tooth surfaces

Results vary between patients, and a night guard is one part of managing grinding rather than a cure for the underlying habit. Where stress or a bite discrepancy is a contributing factor, Dr Pham may also discuss lifestyle strategies or, in some cases, refer for a broader jaw assessment.

The Night Guard Fitting Process

Getting a custom night guard at our Parap clinic is a straightforward, two-appointment process:

Examination — Dr Pham checks your teeth and bite for signs of grinding and discusses your symptoms and sleep habits.
Impression or digital scan — a precise mould or scan of your upper and lower teeth is taken to serve as the basis for your guard.
Laboratory fabrication — your guard is custom-made from these records, typically over one to two weeks.
Fit and adjustment — at your second visit, Dr Pham fits the guard, checks the bite contacts, and makes any adjustments needed for comfort.

Once fitted, we recommend bringing your guard along to routine check-ups so Dr Pham can review its condition and confirm it still fits well.

Related Jaw Concerns: Grinding and TMJ

Teeth grinding and TMJ (temporomandibular joint) disorders are closely related but not the same thing — grinding is a habit that can contribute to jaw joint strain, while TMJ disorder refers more broadly to problems with the jaw joint and surrounding muscles, which can have other causes as well. If your symptoms include jaw clicking, locking, or limited opening in addition to grinding, a dedicated TMJ assessment may be the more appropriate starting point. See our TMJ Treatment page for more detail, or mention both concerns when you book so Dr Pham can assess them together.

Frequently Asked Questions

What's the difference between a night guard and a sports mouthguard?

A night guard (occlusal splint) is designed to be worn while sleeping and is built to withstand the sustained, repetitive forces of grinding and clenching over many hours. A sports mouthguard is built for a completely different job — absorbing a single sharp impact during contact sport — and is typically bulkier with more cushioning around the front teeth. The materials, thickness, and fit are different for each purpose, so a sports guard is not a substitute for a night guard and vice versa. If you need both, Dr Pham will discuss the two separately at our Parap clinic.

How long does a custom night guard last?

A well-made custom night guard typically lasts several years with normal wear, though this varies depending on the severity of your grinding and how well the guard is cared for. Heavy grinders may show wear marks sooner and need a replacement more frequently, while lighter clenchers often get longer service from the same guard. Dr Pham checks the condition of your guard at routine check-ups at our Darwin clinic and will let you know when it is time to consider a replacement.

Is a custom night guard better than one from the chemist?

Custom night guards made at our Parap clinic are fabricated from an impression or digital scan of your own teeth, so the fit is precise. Over-the-counter boil-and-bite guards are bulkier, less accurate, and tend to loosen or distort over a night's wear, which can affect the bite and is less comfortable for extended use. A custom-fitted guard sits securely without excess bulk and is generally more comfortable and more durable, though it does involve a higher upfront cost than a pharmacy option.

Can teeth grinding damage my teeth?

Yes. Grinding places forces on the teeth well beyond normal biting, and over time this can wear away enamel, flatten biting surfaces, chip or crack tooth structure, and put existing fillings and crowns under premature strain. Because most grinding happens during sleep, the damage often builds up gradually before it is noticed. Dr Pham looks for these wear patterns at every check-up, which is often how grinding is first identified.

Does teeth grinding cause headaches or jaw pain?

Grinding and clenching are a common contributor to morning headaches, jaw soreness, and general facial muscle fatigue, because the jaw muscles are working under sustained load for hours during sleep. Not everyone who grinds experiences these symptoms, and headaches can have other causes too, so a clinical assessment at our Parap clinic helps establish whether grinding is a contributing factor in your case.
