Occlusal Splints & Night Guards in Appin & Wollondilly
Custom-Fitted Protection for Teeth Grinding, Jaw Pain & TMJ
If you grind or clench your teeth, especially while you sleep, you might be wearing them down without realising it. Bruxism (the clinical name for grinding) is common, often goes undiagnosed for years, and quietly causes worn enamel, cracked teeth, jaw pain, and morning headaches. The fix is straightforward: a custom-fitted occlusal splint, also called a night guard or bite guard.
Appin Dental Surgery is a QIP-accredited dental practice on Appin Road, rated 5.0 on Google by 95+ patients. With 19+ years of clinical experience and the 30+ year legacy, we make custom occlusal splints for patients across Appin, Wilton, Picton, Douglas Park, Menangle, Tahmoor, Camden, Campbelltown, and the wider Wollondilly Shire.

Understanding Bruxism and TMJ Disorders
Bruxism is the medical term for involuntary teeth grinding and clenching. It often happens during sleep, which is why so many people don't know they do it until a partner mentions the noise or a check-up reveals worn enamel. Untreated, bruxism cracks fillings, fractures teeth, wears restorations like crowns and veneers prematurely, and overworks the jaw muscles.
TMJ (Temporomandibular Joint) disorders affect the joint that connects your jawbone to your skull and the muscles that move it. Symptoms range from clicking and popping when you open your mouth, through to constant jaw pain, restricted opening, and pain that radiates into the ear or temple. Bruxism and TMJ are often connected; the muscle overuse from grinding aggravates the joint, and joint problems can change how you bite, which then causes more grinding.
The good news: a properly fitted occlusal splint is one of the most effective non-invasive treatments for both conditions.
Do You Grind Your Teeth? A Quick Symptom Checklist
Most people who grind their teeth don't realise it. If three or more of these sound familiar, it's worth booking a check-up:
-
Morning headaches, especially in the temples or around the ears
-
Sore or tired jaw muscles when you wake up
-
Worn, flat, or chipped front teeth that didn't used to look that way
-
Increased tooth sensitivity to hot, cold, or sweet things
-
Clicking, popping, or grinding sound when you open or close your mouth
-
Dull pain or aching in your face, particularly later in the day
-
A partner mentions grinding noises while you're sleeping
-
Indentations on your tongue (where it presses against your teeth at night)
-
Tension in your neck and shoulders that won't fully resolve with rest
If you've ticked a few of these, book a consultation at our Appin clinic. We'll examine your bite, look for wear patterns, and tell you whether an occlusal splint is the right next step.
What Exactly Is an Occlusal Splint?
An occlusal splint (also called a night guard or bite guard) is a custom-fitted dental device that sits over your upper or lower teeth, usually worn while you sleep. It's made from durable, smooth dental materials shaped precisely to your bite using digital scans or impressions of your own teeth.
The splint creates a protective layer between your upper and lower teeth so the grinding force lands on the splint, not on your enamel. It also gently repositions your jaw into a more relaxed alignment, which reduces strain on your jaw muscles and the temporomandibular joint.
Custom occlusal splints from a dentist work very differently to over-the-counter "boil-and-bite" guards from chemists. Pharmacy guards are bulky, uncomfortable to sleep in, and often don't sit properly against your teeth, which can actually make grinding worse. We make every splint individually so it fits like a second skin.
How Occlusal Splints Work
Occlusal splints are a simple yet powerful solution to protect your teeth and support your long-term oral health. Custom-made to fit your unique bite, these splints are typically worn during sleep or other stressful periods.
Protecting Your Teeth
Occlusal splints create a protective cushion between your upper and lower teeth. This prevents the direct tooth-to-tooth contact that causes damage such as enamel wear, fractures, and sensitivity from clenching and grinding. By absorbing and redistributing pressure, the splint safeguards your smile.
Easing Jaw Pain and Muscle Tension
By stabilising your jaw and relaxing the surrounding muscles, an occlusal splint helps to reduce muscle tension and alleviate pain. It gently guides your jaw into a balanced position, easing the discomfort often associated with temporomandibular joint (TMJ) disorders.
Types of Occlusal Splints We Offer
Different bite patterns, grinding intensities, and goals call for different splint types. We'll recommend the right one at your consultation, but here are the four we make at our Appin clinic:
Soft Occlusal Splints - Made from flexible, cushioned material. Comfortable to wear, ideal for mild grinding or clenching and patients new to wearing a splint. Generally lasts 1 to 3 years before replacement.
Hard Acrylic Occlusal Splints (Michigan Splint) -
Made from durable hard acrylic. The clinical gold standard for moderate to severe bruxism and TMJ disorders. Sometimes called a Michigan splint. More resistant to grinding wear than soft splints; typically lasts 5 to 10 years.
Dual Laminate Splints - Hard outer shell with a soft inner lining. Combines the durability of acrylic with the comfort of a soft fit. A good middle option for patients who find hard splints too rigid but need more protection than a soft splint provides.
Mandibular Advancement Splints (MAS) - A specialised device that holds the lower jaw forward during sleep to help keep the airway open. We provide MAS appliances for patients with snoring and mild diagnosed Obstructive Sleep Apnoea, but only after a sleep study and in consultation with your GP or sleep physician. We don't fit MAS devices without that medical workup. For moderate-to-severe sleep apnoea, CPAP remains the first-line treatment, and we'll refer you to a sleep specialist if your case calls for it.

What to Expect at Your Splint Appointment in Appin?
Getting a custom occlusal splint takes two appointments, usually 2 to 3 weeks apart. Here's the process:
We examine your teeth, bite, and jaw muscles. We look for wear patterns, check for clicking or restricted opening, and discuss your symptoms in detail. If we think a splint is right for you, we move to scanning.
We capture an accurate model of your upper and lower teeth using digital scans (or traditional impressions if needed). This becomes the template for your splint.
Our local Australian dental laboratory fabricates your splint to the exact shape of your bite. This usually takes 7 to 14 working days.
When your splint arrives, you come back for a fitting. We adjust it on the day for a snug, comfortable fit, and walk you through how to wear and clean it.
We see you again 4 to 6 weeks later to check how the splint is performing, make any adjustments, and confirm your symptoms are improving. Bring your splint to every routine check-up thereafter so we can check fit and wear.
How to Care for Your Occlusal Splint
Proper care of your occlusal splint is essential to keep it effective and comfortable. By following these simple care tips, you can protect your investment and enjoy the full benefits of your occlusal splint. Follow these simple steps to ensure your splint lasts longer and continues protecting your teeth:
Daily Cleaning
Rinse your splint with lukewarm water after each use. Clean it gently with a soft toothbrush and mild, non-abrasive toothpaste or soap to remove plaque and debris.
Deep Cleaning
Once a week, soak your splint in a denture or retainer cleaning solution to keep it fresh and free of bacteria.
Safe Storage
Always store your splint in the protective case provided when not in use. Keep the case in a cool, dry place away from direct sunlight or heat sources.
Avoid Damage
Do not chew or bite on your splint. This can cause cracks or distort its shape, reducing its effectiveness.
Regular Dental Check-ups
Bring your occlusal splint to your dental visits so your dentist can check its fit and make any necessary adjustments to maintain comfort and function.

Frequently Asked Questions About Occlusal Splints
Patients use the terms interchangeably, but technically, a "night guard" is the everyday term, an "occlusal splint" is the clinical term, and both refer to the same device. Custom-fitted versions made by a dentist are far more accurate, comfortable, and durable than the boil-and-bite guards sold at chemists.
The most common signs are morning headaches, jaw pain or stiffness when you wake up, worn or chipped front teeth, increased tooth sensitivity, or a partner mentioning grinding noises at night. If two or more of those sound familiar, book a consultation. We can usually tell within 5 minutes of an exam.
Cost depends on the splint type (soft, hard acrylic, dual laminate, or mandibular advancement) and the complexity of your bite. We give you a full written quote at your initial consultation. Most major Australian health funds cover a portion under Major Dental or Orthodontic Extras.
A splint doesn't always stop the grinding habit, but it absorbs the force so the damage lands on the splint instead of your teeth. Many patients find their grinding intensity reduces over time as the jaw muscles relax. The splint also relieves the morning headaches and jaw soreness most patients come in for.
Soft splints typically last 1 to 3 years; hard acrylic splints can last 5 to 10 years with good care. The biggest factor is grinding intensity. We check your splint at every routine check-up and replace it when it shows signs of wear-through.
The first 1 to 2 weeks usually feel unfamiliar. Most patients are sleeping comfortably with the splint by week 3. If something is genuinely uncomfortable beyond the adjustment period, come back in and we'll adjust the fit.
Yes. We adapt the splint design around any existing dental work. If you've recently completed Invisalign, we coordinate splint wear with your retainer schedule so they don't conflict. The splint actually helps protect crowns and implants from grinding wear.
Most major Australian funds cover a portion under Major Dental or Orthodontic Extras (it varies by fund). We're preferred providers for nib and Medibank. Bring your card and we'll process your rebate on the spot with HICAPS.
A specific type called a Mandibular Advancement Splint (MAS) can help with snoring and mild diagnosed Obstructive Sleep Apnoea. We only fit MAS appliances after a sleep study confirms the diagnosis, in consultation with your GP or sleep physician. For moderate-to-severe sleep apnoea, CPAP is usually first-line treatment.
