You wake up with a sore jaw. Maybe your partner nudged you in the night because of the noise. Or maybe your dentist has been quietly flagging that your teeth are looking a little flatter than they used to. If any of that sounds familiar, there’s a good chance you’re grinding your teeth, and you may not even know it.
Bruxism, the medical term for teeth grinding or clenching, is far more common than most people realise. According to Better Health Victoria, around half of all Australians grind their teeth at some point, with roughly 5% doing it regularly and forcefully enough to cause real damage. The tricky part? Most of the damage happens silently, over the years, before it becomes obvious.
The good news is that a custom dental splint, fitted by a professional dentist, is widely regarded as one of the most effective ways to protect your smile. If you’re in Greensborough or the surrounding Melbourne suburbs, G Dental offers exactly that.
What Is Bruxism and Why Does It Happen?
Bruxism is the involuntary clenching or grinding of teeth. It can happen while you’re asleep (sleep bruxism) or during the day when you’re awake (awake bruxism). Most people don’t realise they’re doing it until a partner mentions the sound, or a dentist spots the telltale wear on their teeth at a check-up.
There isn’t always one single cause, but the most common triggers include:
- Stress and anxiety — this is the big one. Emotional tension often manifests physically in the jaw.
- Sleep disorders, particularly sleep apnoea, which is closely linked to night-time grinding.
- Caffeine and alcohol, especially when consumed late in the day.
- Certain medications, including some antidepressants.
- Bite misalignment, where the teeth don’t sit comfortably together.
Sleep bruxism and awake bruxism are treated slightly differently, so it’s worth discussing both with your dentist. A 2024 systematic review published in the Journal of Clinical Medicine found that nearly one in four adults may experience awake bruxism, which is higher than many people would expect.
The Damage Teeth Grinding Does to Your Smile Over Time
This is where things get serious. Bruxism is one of those conditions that builds quietly and then suddenly becomes a big dental bill.
Here’s what untreated grinding can do to your teeth and jaw over time:
| Problem | What It Looks Like |
| Worn tooth enamel | Flat, shortened teeth; loss of natural shape |
| Chipped or cracked teeth | Damage to tooth structure, often without pain at first |
| Damaged fillings, crowns, and veneers | Restorations are wearing out faster than expected |
| Jaw pain and TMJ disorder | Aching, clicking, or locking jaw |
| Chronic morning headaches | Tension in the jaw muscles radiating to the head |
| Tooth sensitivity | Enamel loss exposes the inner layers of teeth |
The worst part is that many people don’t notice the wear on their teeth until it’s quite advanced. According to Healthdirect Australia, grinding can cause cracking and, in severe cases, tooth loss if left unaddressed.
Jaw pain is another significant concern. Research published via StatPearls (NCBI, updated 2024) confirms that severe bruxism can restrict movement of the temporomandibular joint (TMJ) and cause persistent morning jaw pain and headaches. These symptoms are easy to write off as stress or poor sleep, which is exactly why so many people in Melbourne and across Australia go years without realising bruxism is the root cause.
What Is a Dental Splint and How Does It Work?
A dental splint (also called an occlusal splint or nightguard) is a custom-made appliance, usually crafted from hard acrylic, that fits over your upper or lower teeth. You wear it while you sleep.
Here’s what it does:
- Cushions the bite so that grinding forces are absorbed by the splint rather than your natural teeth.
- Keeps tooth surfaces apart, preventing them from making damaging contact.
- Reduces muscle tension in the jaw by encouraging a more relaxed jaw position overnight.
- Protects existing dental work like crowns, veneers, and fillings from premature wear.
It’s worth knowing that a professional, custom-fitted splint is a very different thing from the boil-and-bite guards you’ll find at the chemist. Those over-the-counter options are made from soft material, don’t fit precisely, and in some cases can actually increase jaw clenching. StatPearls notes that hard acrylic-resin stabilisation splints are more effective than soft splints, which can worsen clenching behaviour in some patients.
A custom splint from a dental professional is designed specifically for your bite, giving you far better protection and a more comfortable fit.
Getting a Teeth Grinding Splint in Greensborough: What to Expect at G Dental
If you’ve never had a dental splint before, the process is simple and nothing to worry about. Here’s what typically happens when you come into G Dental in Greensborough:
- Consultation and assessment — Your dentist will examine your teeth for signs of wear, assess your bite, and discuss your symptoms. Even if you’re not sure whether you grind, a dentist can often spot the signs before you’re aware of them.
- Dental impressions or digital scan — Precise measurements of your teeth are taken so that the splint fits your mouth exactly, not just “close enough.”
- Fabrication — Your custom splint is made in a dental laboratory, which usually takes one to two weeks.
- Fitting appointment — You’ll come back in, try the splint, and your dentist will make any adjustments needed to ensure it’s comfortable and sits correctly.
- Ongoing monitoring — At your regular dental check-ups, your dentist will inspect the splint for wear and check that it’s still doing its job.
The whole process is professional, thorough, and tailored specifically to your teeth. That’s something a chemist’s shelf can’t replicate.
Does a Splint Cure Teeth Grinding?
This is a fair question, and it deserves an honest answer: no, a splint doesn’t stop you from grinding. What it does is protect your teeth from the damage that grinding causes.
Think of it like a seatbelt. It doesn’t prevent accidents, but it protects you when one happens.
For the best long-term outcome, it helps to address the underlying causes alongside wearing the splint:
- Stress management through mindfulness, exercise, or counselling.
- Reviewing medications with your GP if you suspect a drug is contributing.
- Treating sleep disorders like sleep apnoea, which has a strong link to night-time grinding.
If your grinding has already caused jaw pain or suspected TMJ issues, it’s worth discussing that with your dentist, too. G Dental offers TMJ treatment alongside splint therapy, so you’re not left managing one problem while another goes unaddressed.
How to Care for Your Dental Splint
Getting a custom splint is an investment in your smile, so it’s worth taking good care of it. Here are some simple habits to keep your skin in good condition:
- Rinse and clean it every morning with a soft toothbrush and mild soap or a denture-cleaning tablet. Don’t use hot water, as it can warp the acrylic.
- Store it in the case provided when you’re not wearing it, away from pets and out of direct sunlight.
- Bring it to your dental check-ups so your dentist can check for wear and make adjustments if needed.
- Replace it when necessary — most splints last between two and five years, depending on how much you grind.
If you notice the splint cracking, changing shape, or feeling less comfortable, book in earlier rather than waiting for your next scheduled appointment.

Frequently Asked Questions
How do I know if I grind my teeth?
Common signs include a sore or tight jaw in the morning, frequent morning headaches, tooth sensitivity, or a partner telling you they hear grinding at night. Your dentist may also spot signs of wear on your teeth during a routine check-up, even before you notice any symptoms.
Is a custom splint better than one from the chemist?
Yes, significantly. Custom splints from a dental professional are made from hard acrylic, fitted precisely to your bite, and far more protective. Over-the-counter guards are made from soft material, fit poorly, and can sometimes increase jaw clenching.
How much does a teeth-grinding splint cost in Greensborough?
The cost varies depending on the complexity of your case and your dental health fund coverage. The best step is to book a consultation at G Dental, where you’ll receive a clear breakdown of what’s involved.
Can children grind their teeth, too?
Yes. Better Health Victoria notes that grinding is common in children, but most grow out of it as their jaws develop. A dentist can assess whether treatment is needed or whether it’s safe to monitor.
Will I have to wear the splint forever?
Not necessarily. Some people wear a splint long-term to manage ongoing grinding, while others only need it during particularly stressful periods. Your dentist will guide you based on how your teeth and symptoms respond over time.
