Custom Night Guards vs Chemist Splints: Teeth Grinding Relief & Cost Melbourne 2026

Stop Teeth Grinding: The Melbourne Guide to Custom Night Guards

Do you wake up in the morning with a dull headache, stiff jaw muscles, or sensitive teeth? Or has your partner mentioned loud clicking or grinding sounds coming from your pillow at night?

If so, you are likely experiencing nocturnal bruxism: the involuntary grinding or clenching of teeth during sleep. Bruxism affects over 15% of Australian adults, exerting heavy biting forces that wear down natural tooth enamel, crack fillings, and strain the temporomandibular joint (TMJ).

At Oak Park Dental & Denture Clinic on Snell Grove in Oak Park, our on-site dental laboratory crafts custom-fitted occlusal splints and night guards that absorb heavy bite forces and protect your smile.

Why Chemist "Boil-and-Bite" Splints Do More Harm Than Good

When facing jaw pain or tooth wear, many Melbourne patients purchase over-the-counter (OTC) night guards from local pharmacies. While inexpensive upfront ($25 to $50), generic plastic appliances carry significant dental risks:

The Danger of Soft Chemist Guards

Soft, chewy drugstore guards trigger your brain's chewing reflex, similar to chewing gum. Instead of relaxing your jaw, soft chemist guards cause many patients to clench harder throughout the night, aggravating jaw joint inflammation. Uneven thickness can also cause back molars to hit first, leading to permanent bite shifts.

3 Types of Custom Night Guards Crafted in Our Lab

1. Hard Acrylic Occlusal Splint (Michigan / Flat-Plane Splint)

• Best For: Heavy grinders, severe bruxism, TMJ pain, and patients with porcelain crowns or dental implants.
• Features: Made from clear, medical-grade PMMA acrylic polished to a mirror finish. Provides a smooth biting platform that allows the lower jaw to slide freely without catching.
• Longevity: 5 to 8+ years.

2. Dual-Laminate (Hard-Exterior / Soft-Interior) Splint

• Best For: Moderate grinders who want inner cushioning against sensitive teeth paired with hard outer grinding protection.
• Features: A soft polyurethane inner lining bonded to a rigid acrylic outer shell.
• Longevity: 3 to 5 years.

3. Soft Custom Guard

• Best For: Light clenchers or stress grinders requiring mild protection.
• Features: Vacuum-formed from medical-grade soft polymer.
• Longevity: 1 to 3 years.

Frequently Asked Questions

How much does a custom night guard cost in Melbourne?

A custom laboratory-fabricated occlusal splint in Melbourne typically ranges from $450 to $750. If you have private health insurance with dental extras, item code 965 or 961 can cover a significant portion of this fee.

How long does it take to get used to wearing a night guard?

Most patients adapt to sleeping with a custom night guard within 4 to 7 nights. Because the appliance is molded to your exact dental impressions, it does not gag you or fall out during sleep.

How do I clean and store my occlusal splint?

Rinse your splint under cold or lukewarm water after waking up and brush it gently with a soft toothbrush and mild soap. Never use hot water, as heat can warp the acrylic. Store it dry inside its ventilated protective case.

Does a night guard stop teeth grinding permanently?

A night guard does not stop the neurological habit of clenching, but it creates a protective barrier that prevents tooth wear, stops enamel fractures, relieves morning jaw soreness, and protects expensive dental crowns or dentures from damage.
