What Is Bruxism?

Bruxism is the term for teeth grinding and clenching, most commonly during sleep. Many people are unaware they do it until a partner mentions it or a dentist notices wear patterns. Stress is a common contributing factor, although it can also occur without an obvious cause.

Common signs include flattened or worn enamel, jaw discomfort on waking, morning headaches, tooth sensitivity, and cracked or chipped teeth. If you notice these changes, it is worth having your teeth and jaw assessed.

Why Teeth Grinding Can Be a Concern

Grinding places repeated pressure on teeth, muscles, and jaw joints. Over time, this can lead to enamel wear, sensitivity, fractures, and strain through the temporomandibular joints (TMJ). Because enamel does not regenerate, early identification is important.

Ongoing grinding may also contribute to jaw tension and disrupted sleep. The longer it continues, the more complex restorative care may become. An assessment allows changes to be identified and managed appropriately.

Custom Nightguard vs Store-Bought Options

	Custom Nightguard	Store-Bought
Fit	Designed for your bite	Generic shape
Pressure	Even distribution	Can worsen jaw tension
Material	Durable, long-lasting	Often soft and short-lived
Comfort	Comfortable for sleep	Bulky
Protection	Long-term solution	Temporary at best

A poorly fitted nightguard can sometimes make symptoms worse.

Types of Dental Splints

Following your assessment, Dr Tony Goswell (Dentist) may recommend:

A soft nightguard for mild grinding
A hard acrylic splint where more significant wear is present
A stabilisation or TMJ splint when jaw position or joint loading requires consideration

The most suitable appliance depends on your individual presentation and will be discussed during your appointment.

The Assessment & Fitting Process

Dr Tony will examine your teeth and jaw for signs of wear, bite alignment, and muscle or joint tenderness. A digital scan or impression is taken to help ensure a precise fit.

Once fabricated, you will return for fitting and minor adjustments if required. Follow-up appointments are recommended to monitor appliance wear and review any changes over time.

When to Seek an Assessment

Consider booking an appointment if you experience:

Morning headaches or facial tension
A clicking, popping, or sore jaw
Tooth sensitivity without another clear cause
Chipped, cracked, or visibly worn teeth

Early assessment may help reduce the risk of further wear and the need for more extensive restorative care.

Frequently Asked Questions

What is the difference between a nightguard and a splint?

A nightguard is designed to protect teeth from the effects of grinding during sleep. A splint is more precisely shaped and may be recommended when jaw position or joint function requires additional consideration. Dr Tony will advise what is appropriate after your assessment.

How do I know if I grind my teeth?

Many people are unaware until a dentist identifies wear patterns. Signs may include jaw soreness in the morning, headaches, sensitivity, and flattened tooth surfaces.

Can a nightguard help with TMJ discomfort?

A correctly fitted appliance may help reduce load on the temporomandibular joint in some cases. This will be individually assessed and discussed with you.

How long does a custom nightguard last?

With proper care, a custom appliance may last several years, although heavier grinders may wear through them sooner. Wear is reviewed at check-up appointments and replacement advised when necessary.

Are over-the-counter nightguards effective?

Over-the-counter nightguards can offer short-term protection, but they are not individually fitted to your bite. Because the fit varies, they may feel bulky or less secure. A custom-made appliance is designed specifically for your teeth and provides greater comfort and stability.

Will it stop grinding completely?

A nightguard or splint protects teeth from the effects of grinding but does not eliminate the habit itself. Addressing contributing factors, such as stress, may help reduce frequency for some people.

Is the process painful?

No. Taking a digital scan or impression is straightforward and non-invasive. The fitting appointment is typically brief, and minor adjustments can be made to ensure the appliance feels comfortable.

Can I claim this on private health?

Many private health funds include cover for custom dental appliances under extras policies. We recommend checking directly with your fund, as entitlements vary.
