Teeth Grinding Splints & Night Guards
Protect Your Teeth From Grinding & Clenching
If you grind or clench your teeth, especially while sleeping, the pressure can gradually wear or damage your teeth and contribute to jaw discomfort.
At Macquarie Dentists in Macquarie Park, we provide custom-made grinding splints (night guards) designed to fit your teeth and bite precisely for comfortable, reliable protection.
SIGNS YOU MAY BE GRINDING YOUR TEETH
Could You Benefit From a Grinding Splint?
Many people grind or clench their teeth without realising it, especially while they sleep. You may notice:
- Worn, chipped or cracked teeth
- Sensitive teeth
- Jaw tightness, soreness or tenderness
- Morning headaches
- Damaged fillings, crowns or veneers
Sometimes there are no obvious symptoms and the first signs are noticed during a routine dental examination .
WHY TEETH GRINDING MATTERS
Grinding Can Gradually Wear Down Your Teeth
Your teeth are built to withstand everyday chewing, but grinding can expose them to repeated excessive pressure night after night.
Over time, this can gradually weaken and wear away healthy tooth structure. Once enamel and tooth structure are lost, they cannot grow back, and more extensive dental treatment may eventually be needed.
A grinding splint creates a protective barrier between your teeth, helping reduce the direct wear and damage caused by grinding while you sleep.
What Is an Occlusal Splint?
An occlusal splint is a custom-made dental appliance worn over the teeth, usually while sleeping. It is designed to create a protective barrier between the upper and lower teeth while also providing a carefully controlled surface for your teeth to contact. Your splint is individually made based on your teeth and bite, rather than using a one-size-fits-most shape. Depending on your needs, the splint may be made for either the upper or lower teeth.
WHAT’S THE DIFFERENCE?
Custom Splint VS Chemist Night Guard
Chemist night guards are typically pre-formed or boil-and-bite appliances designed to fit a wide range of mouths. They can provide a barrier between your teeth, but because they are not made specifically for you, they may feel bulky, move during sleep or fit unevenly.
Custom dental splints are made specifically for your teeth and bite following a dental assessment and digital scan. This provides a precise, secure fit and allows the splint to be carefully checked and adjusted once it is in your mouth.

DIFFERENT APPLIANCES HAVE DIFFERENT PURPOSES
A Grinding Splint Isn’t the Same as a Sports Mouthguard or Sleep Apnoea Device
Dental appliances can look similar, but they are designed for different purposes.
A grinding splint is designed primarily to protect your teeth from clenching and grinding while you sleep.
If you need protection during contact sport, see our custom sports mouthguard page.
If you have concerns about snoring or obstructive sleep apnoea, a different type of oral appliance may be required. Learn more about sleep apnoea and snoring appliances.
These appliances should not be used interchangeably because their design and purpose are different.
ALREADY HAVE A SPLINT?
Bring your splint with you to your regular dental appointments so we can check that it is still fitting comfortably and doing its job. It’s also a good opportunity to check your teeth for any new signs of grinding or wear.
What About Jaw Pain and Headaches?
Grinding and clenching can contribute to jaw muscle tension, facial soreness and morning headaches in some people.
However, these symptoms can also have other causes.
If you experience persistent jaw pain, clicking, locking or restricted movement, we’ll assess your symptoms and discuss whether a splint is appropriate or whether further investigation may be needed.
A grinding splint should not be viewed as a treatment for every type of jaw pain.
Frequently Asked Questions (FAQs)
Does a splint stop me from grinding my teeth?
Not necessarily. A splint is primarily designed to protect your teeth from the effects of grinding and clenching rather than eliminate the habit itself.
Should I get a hard or soft night guard?
The most appropriate material depends on your teeth, bite and grinding pattern. For many patients with significant grinding, a professionally made rigid or carefully designed splint may provide greater durability and allow more precise adjustment of the bite. We’ll recommend an option based on your individual assessment.
Are chemist night guards safe?
Over-the-counter night guards can provide a barrier between the teeth for some people, but they are not individually fitted or adjusted to your bite. If you have persistent grinding, significant tooth wear, dental restorations or jaw symptoms, it is worth having your teeth and bite assessed before relying on a generic appliance long term.
How do I know if I grind my teeth?
Common signs include flattened or worn teeth, cracks, sensitivity, morning jaw tightness and headaches. Your dentist may also identify characteristic wear patterns even if you are unaware that you grind.
Can grinding crack a tooth?
Yes. Heavy or repeated grinding can place significant forces on the teeth and may contribute to cracks, fractures or damage to existing restorations.
Can a splint protect crowns, veneers and fillings?
A splint can help reduce direct grinding forces on natural teeth and dental restorations. This can be particularly helpful for patients who have a history of breaking or wearing their dental work.
Will a splint help my jaw pain?
It may help some patients when grinding or clenching contributes to muscle-related jaw discomfort. However, jaw pain can have many causes, so an assessment is important before recommending a splint.
How long does a dental splint last?
This varies depending on how heavily you grind, how often the splint is worn and the material used. Some patients may use the same appliance for several years, while heavy grinders may wear through one sooner.
How do I clean my splint?
Rinse it after wearing and clean it regularly using the instructions provided at your fitting appointment. Store it in its protective case and avoid exposing it to hot water, which may distort some materials.
Can I claim a grinding splint through private health insurance?
Depending on your policy, private health insurance may contribute towards the cost of an occlusal splint. Macquarie Dentists offers HICAPS for on-the-spot claims. Your rebate will depend on your individual cover.
