Bruxism
Treatment

Early signs include flattened or worn tooth edges, unexplained sensitivity, jaw tightness or soreness upon waking, morning headaches, and facial muscle fatigue. Cracked fillings or chipped enamel without a clear cause may also indicate grinding. Many patients are unaware they grind until clinical examination reveals wear patterns.

Yes. Porcelain crowns and veneers can fracture or chip under excessive grinding forces. Composite restorations wear faster. Implants are particularly vulnerable — they lack the natural shock-absorbing periodontal ligament, so sustained overload can lead to component loosening or failure. A custom occlusal splint is strongly recommended for patients with restorations or implants.

Yes. The excessive lateral forces generated during grinding can contribute to gum recession, particularly at the necks of teeth. It can also cause abfraction lesions — notch-like defects at the gumline where tooth structure is stressed. Gum recession associated with grinding may require periodontal assessment in addition to splint therapy.

Yes. Grinding is common in children, often associated with developing dentition, stress, or airway-related factors. In many children, it resolves as the permanent teeth erupt and the bite settles. Routine monitoring is typically recommended rather than immediate appliance therapy, as primary teeth are transitional.

A clinical occlusal assessment evaluates how your teeth come together and identifies premature contacts, uneven forces, or bite imbalances that may trigger or worsen the condition. Signs include grinding on one side, specific worn teeth, or jaw deviation on closing. Digital bite analysis or study models may be used to assess the occlusion in detail.

Yes. Grinding generates forces well above normal chewing. Over time, this causes progressive enamel loss, tooth flattening, crack formation, fractures, and increased risk of pulp damage requiring root canal treatment. Without protective intervention, damage accumulates and may require extensive restorative treatment.

Sustained clenching and grinding places the jaw joints under repetitive load, which can cause inflammation, disc displacement, joint clicking, restricted opening, and chronic facial pain. Not all TMJ patients grind, and not all grinding patients develop TMJ disorders, but the relationship is well established. Addressing the habit is often the first step in managing associated jaw joint problems.

Yes. Sustained jaw muscle activity places significant strain on the muscles of the jaw, temples, and neck. This can cause tension headaches, particularly in the morning after sleep grinding, as well as neck and shoulder pain. Occlusal splint therapy reduces muscle strain and can alleviate associated headache patterns.

Some private health insurance extras policies include partial rebates for occlusal splints under dental or major dental cover. Coverage varies between insurers and policy levels. We recommend checking with your fund prior to treatment. A personalised quote and item numbers are provided so you can determine your rebate.
