Nightguards for Teeth Grinding in Sandgate

A nightguard is a custom-made guard you wear over your teeth while you sleep. It puts a barrier between your upper and lower teeth to help reduce the effects of grinding and clenching. It doesn’t stop the grinding itself. Your dentist can check for signs of grinding.

Teeth grinding and clenching — known as bruxism — is a common condition that many people experience during sleep without even realising it.

Over time, the repeated pressure can wear down tooth enamel, cause cracks and chips, strain the jaw muscles and joints, and damage existing dental work such as fillings and crowns. A custom nightguard provides a protective barrier between your upper and lower teeth, helping to reduce the effects of grinding and clenching while you sleep. At Sandgate Family Dental, our experienced team provides custom-fitted nightguards designed for comfort and durability.

What Is Bruxism?

Bruxism is the involuntary grinding, gnashing or clenching of the teeth. It most commonly occurs during sleep (sleep bruxism), though some people also clench or grind during the day (awake bruxism), often in response to stress, concentration or habit.

Sleep bruxism can be particularly damaging because you're unaware it's happening. The forces generated during grinding can be significantly greater than those used during normal chewing, which is why the effects tend to accumulate over time — often without noticeable symptoms until the damage is already well advanced.

The exact causes of bruxism aren't fully understood, but contributing factors may include:

Stress and anxiety
Sleep disorders such as obstructive sleep apnoea
An abnormal bite or tooth alignment
Lifestyle factors such as caffeine, alcohol and smoking
Certain medications (particularly some antidepressants)

If your dentist notices signs of bruxism at a routine check-up, they'll discuss your symptoms and recommend an appropriate management approach.

Signs You May Be Grinding Your Teeth

Because sleep bruxism happens unconsciously, many people aren't aware they grind their teeth until a dentist identifies the signs or symptoms develop. Common indicators that you may be grinding or clenching include:

Flat, worn or shortened teeth (particularly the front teeth or canines)
Chips, cracks or fractures in teeth that can't be explained by other causes
Jaw pain, stiffness or fatigue — especially in the morning
Frequent headaches (particularly tension-type headaches upon waking)
Tooth sensitivity to hot, cold or sweet foods and drinks
Clicking, popping or discomfort in the jaw joint (temporomandibular joint or TMJ)
Soreness in the face, temples or ear area
A partner noticing grinding sounds during the night

If any of these sound familiar, mention it at your next dental check-up. Your dentist can examine your teeth and jaw for signs of bruxism and discuss whether a nightguard would be helpful.

How a Custom Nightguard Helps

A nightguard (also called an occlusal splint) is a custom-made dental appliance that you wear over your teeth while you sleep. It's typically made from a durable, smooth material that fits snugly over the upper or lower teeth.

A nightguard works by creating a physical barrier between the upper and lower teeth, preventing direct tooth-on-tooth contact during grinding.

It distributes the forces of clenching more evenly across the arch, reducing concentrated pressure on individual teeth.

The smooth surface of the guard can reduce the friction and resistance that contribute to grinding movements.

By reducing strain on the jaw muscles and the temporomandibular joint, a nightguard can help relieve jaw discomfort, morning headaches and facial tension in some patients.

It's important to understand that a nightguard manages the effects of bruxism rather than curing the underlying cause. It is often a practical way to help protect the teeth and reduce symptoms. If your dentist suspects an underlying sleep disorder or other contributing factor, they may recommend further investigation.

Custom Nightguards vs. Store-Bought Options

As with sports mouthguards, there's a significant difference between a professionally fitted nightguard and one purchased over the counter.

Custom-Fitted Nightguards

A custom nightguard is made from a precise scan or impression of your teeth, so it should fit comfortably and stay in place throughout the night. The material thickness and design can be tailored to the severity of your grinding and the specific needs of your bite. Because the fit is accurate, custom nightguards are generally thinner and more comfortable than generic options, making them easier to sleep with and more likely to be worn consistently.

Over-the-Counter Nightguards

Pharmacy-bought boil-and-bite nightguards provide some level of protection, but the fit is often bulky and imprecise. A poor fit can cause discomfort, interfere with breathing or sleeping, and in some cases may actually encourage further clenching. They also tend to wear out more quickly than custom appliances.

For patients who grind regularly, a custom-fitted nightguard from your dentist can provide a more comfortable, durable and effective solution.

The Nightguard Process

Getting a custom nightguard at Sandgate Family Dental is a straightforward process, usually completed across two appointments.

Assessment Your dentist will examine your teeth and jaw for signs of bruxism — such as wear patterns, cracks, muscle tenderness and joint issues. They'll discuss your symptoms and history to understand the extent of the problem. If a nightguard is appropriate, impressions or digital scans of your teeth are taken. If impressions make you gag, a digital scan may be an option — see managing a gag reflex.
Fabrication Your nightguard is custom-made from your scan or impression to fit your exact bite. The material type and thickness are selected based on the severity of your grinding.
Fitting and Adjustment Once your nightguard is ready, you'll return for a fitting appointment. Your dentist will check the fit, comfort and bite, making any adjustments needed so the nightguard sits securely and comfortably. You'll receive instructions on how to wear and care for it.

Caring for Your Nightguard

A well-maintained nightguard can last for several years, though the lifespan depends on the severity of your grinding.

Rinse your nightguard with cool or lukewarm water each morning after use. Clean it regularly with a soft toothbrush and mild soap or a dedicated appliance cleanser — avoid hot water and abrasive toothpaste, which can warp or scratch the material. Allow it to air dry completely before storing it in the ventilated case provided.
Keep your nightguard away from heat, direct sunlight and pets (dogs in particular are known for chewing them). Bring it to your regular dental check-ups so your dentist can inspect it for wear, thinning or changes in fit.
If your nightguard cracks, becomes loose, or develops rough spots, book an appointment to have it assessed — continuing to wear a damaged nightguard may reduce its effectiveness or irritate your gums.

The Long-Term Effects of Untreated Bruxism

Without management, chronic teeth grinding can lead to progressive wear that gradually changes the shape and height of your teeth. Over time, this can affect your bite and the way your jaw functions. Teeth that have been significantly worn may eventually need restoration with dental crowns, veneers or dental bonding to rebuild their shape and function.

Severe grinding can also crack or fracture teeth, sometimes to the point where a tooth can't be saved and needs to be extracted. Replacing a missing tooth with a dental bridge, implant or denture is considerably more involved and costly than preventing the damage in the first place.

Bruxism can also contribute to temporomandibular joint (TMJ) disorders — causing chronic jaw pain, clicking, limited mouth opening and headaches. While a nightguard can help manage these symptoms, some patients may benefit from additional treatment or referral to a TMJ specialist. Learn more about TMJ and jaw pain.

A nightguard is a relatively simple, non-invasive measure that can help protect your teeth from further damage and reduce the symptoms of grinding while you sleep.

Health Fund and Payment Options

Custom nightguards are generally covered under the general dental or preventive component of most health fund extras policies. The amount you receive back will depend on your level of cover and your fund's fee schedule.

At Sandgate Family Dental, we process health fund claims on the spot using HICAPS, so you only need to pay the gap at the time of your visit. We are a preferred provider for HCF, nib, CBHS and HIF. Patients with these funds may receive higher rebates on their nightguard. Visit our health funds page for more details.

Frequently Asked Questions About Nightguards

How do I know if I grind my teeth at night?

Many people are unaware they grind their teeth because it happens during sleep. Common signs include waking with jaw pain or stiffness, frequent morning headaches, worn or flattened teeth, tooth sensitivity, and a partner noticing grinding sounds. Your dentist can identify wear patterns and other signs of bruxism during a routine check-up.

Will a nightguard stop me from grinding?

A nightguard doesn't stop the grinding habit itself — it helps protect your teeth and jaw from the damaging effects of grinding. By creating a barrier between your teeth and distributing the forces more evenly, it helps prevent wear, cracks and jaw strain. If the underlying cause of your bruxism is stress, sleep-related or medication-related, your dentist may suggest additional strategies.

Is a custom nightguard more comfortable than a store-bought one?

Generally, yes. A custom nightguard is made from a scan or impression of your teeth, so it fits precisely and is thinner and less bulky than over-the-counter options. This makes it more comfortable to sleep with and more likely to be worn consistently — which is important for it to be effective.

How long does a custom nightguard last?

The lifespan of a nightguard depends on the severity of your grinding. For moderate grinders, a custom nightguard can last several years. Severe grinders may wear through a nightguard more quickly. Your dentist will check the condition of your nightguard at your regular check-ups and let you know when it needs replacing.

Can I wear a nightguard if I have crowns or bridges?

Yes. In fact, a nightguard is often recommended specifically to protect existing dental work such as crowns, bridges and fillings from the forces of grinding. The nightguard is made to fit over your teeth including any restorations.

Do I need to wear a nightguard every night?

For consistent protection, it's generally recommended to wear your nightguard every night. Grinding tends to happen intermittently and unpredictably — some nights more than others — so wearing it consistently helps protect your teeth and jaw.
