Common Presentations We Manage
Bruxism isn’t one-size-fits-all. Understanding when and how it happens guides the right management approach for each person.
Sleep Bruxism
Grinding or clenching during sleep is the most common presentation. Most people are unaware it’s happening until a partner hears the sounds or a dentist identifies flattened cusps, worn enamel, or scalloped tongue edges at a check-up. Sleep bruxism is considered a sleep-related movement disorder and may be associated with sleep apnoea, snoring, or periods of stress.
Awake Bruxism (Daytime Clenching)
Awake bruxism tends to involve clenching rather than grinding, and typically occurs during periods of concentration, stress, or emotional tension. Many people clench unconsciously while driving, working at a screen, or during stressful situations. Awareness-based strategies play a bigger role in managing this type.
Mild to Moderate Bruxism
Early or mild bruxism often shows up as subtle enamel wear on biting surfaces, occasional jaw stiffness in the morning, or mild sensitivity to cold foods. At this stage, a custom occlusal splint can protect the teeth and prevent the condition from progressing, while the underlying triggers are addressed.
Severe or Longstanding Bruxism
In people who have ground their teeth for years, we may see significant enamel loss, cracked or fractured teeth, increased tooth sensitivity, and chronic jaw muscle fatigue or pain. Restorative work may eventually be needed to rebuild worn tooth surfaces, but management of the underlying grinding habit remains essential to protect any dental work long term.
How to Tell if You May Be Grinding
These are some of the most common signs that bruxism may be affecting you. A dental examination is the most reliable way to assess what’s happening.
- Jaw soreness or stiffness - particularly in the morning after sleep bruxism, or in the afternoon after a stressful day
- Headaches - often described as a dull ache starting at the temples, related to prolonged muscle contraction
- Worn or flattened teeth - enamel loss on biting surfaces, sometimes with a noticeably “flat” appearance to the back teeth
- Tooth sensitivity - increased sensitivity to cold or sweet foods as enamel thins
- Cracked or chipped teeth - fractures that occur without any obvious trauma
- Facial muscle pain - aching or tenderness in the muscles around the jaw, cheeks, or temples
- Jaw clicking or popping - sounds from the temporomandibular joint (TMJ) that may accompany bruxism-related muscle tightness
- Disturbed sleep - your partner hears grinding sounds, or you wake feeling unrefreshed
- Indentations on the tongue or cheeks - from habitual pressing or biting during sleep
How We Assess and Manage Bruxism
We take a thorough, step-by-step approach to understand your situation fully before recommending a management plan.
Comprehensive Assessment
We begin with a detailed examination of your teeth, bite, jaw joints (TMJ), and surrounding muscles. We look for signs of wear, asymmetry, and tenderness, and take a thorough history to understand when symptoms occur and what factors may be contributing. We also consider whether related issues like sleep apnoea or headaches should be explored further.
Custom Occlusal Splint Fabrication
Where an occlusal splint (night guard) is recommended, we take precise impressions of your teeth and have a custom-fitted device made by a dental laboratory. This is not a generic chemist mouthguard, it is designed specifically for your bite, balancing the forces across your teeth and providing a protective cushion. Fit and comfort are checked at a review appointment and adjusted as needed.
Trigger Identification and Lifestyle Advice
We discuss contributing factors such as stress, caffeine, alcohol, posture, and sleep habits. For awake bruxism, we can offer practical awareness strategies to help interrupt the clenching cycle. Where sleep-related breathing disorders may be a factor, we can provide a referral to the appropriate specialist.
Monitoring and Long-Term Protection
Bruxism is often a long-term condition rather than something that resolves after a single treatment. We incorporate ongoing monitoring of tooth wear into your regular check-ups, review splint condition and fit over time, and discuss further options if symptoms progress. For severe cases with significant muscle involvement, we may discuss adjunctive options such as muscle relaxant therapy.

Bruxism FAQs
Will I know if I’m grinding my teeth at night?
Often not, sleep bruxism typically happens without any conscious awareness. You may only find out through a partner who hears the sounds, or when a dentist identifies signs of wear at a check-up. Some people notice clues like jaw aching or headaches on waking, but these symptoms can have other causes too. A dental examination is the most reliable way to assess whether bruxism is occurring.
What is an occlusal splint and how does it help?
An occlusal splint (also called a night guard or bite splint) is a custom-fitted acrylic device that fits over your upper or lower teeth. It creates an even surface for the opposing teeth to contact, reducing uneven wear forces and providing a protective barrier. It doesn’t stop the grinding habit itself, but it protects your natural teeth from the damage that grinding would otherwise cause. Many people also find they experience less jaw soreness when wearing one.
Can a chemist mouthguard do the same job?
Over-the-counter mouthguards are inexpensive but generally don’t fit as precisely as a custom-made splint. A poor fit can cause discomfort, interfere with your bite, and in some cases make clenching worse. For occasional situations or sport, a chemist guard may serve a short-term purpose, but for managing ongoing bruxism we recommend a lab-fabricated custom splint for better comfort, fit, and durability.
My teeth look fine, do I still need treatment?
Enamel wear can be subtle in the early stages and difficult to see without magnification and a trained eye. Bruxism can also cause muscle and joint symptoms before significant tooth damage is visible. If there are signs of early wear or symptoms that suggest bruxism, managing it now is far more conservative and cost-effective than waiting until restorative treatment is needed. Prevention is much simpler than repair.
Is bruxism related to stress?
Stress is one of the most commonly reported contributing factors, particularly for awake bruxism (daytime clenching). However, bruxism can also occur in people who report low stress levels, and it has been associated with factors including sleep disorders, certain medications, caffeine, alcohol, and genetic predisposition. The relationship is complex, and management usually involves addressing multiple contributing factors rather than just one.
Can bruxism cause headaches?
Yes, chronic overactivation of the jaw muscles (particularly the masseter and temporalis) can contribute to headaches, often described as a dull ache around the temples, forehead, or back of the head. These are often most noticeable in the morning. Properly fitted occlusal splints may help reduce this muscle overload, though headaches can have many causes and we recommend mentioning them to your GP as well.
Will a night guard fix my bruxism permanently?
An occlusal splint protects your teeth from the effects of bruxism but generally doesn’t eliminate the underlying grinding habit. Many people continue to need a splint long-term for protection. Addressing contributing factors, stress, sleep quality, caffeine and alcohol intake, can help reduce the severity. Some people find their bruxism diminishes over time as life circumstances change; others manage it as an ongoing condition.

A dental check-up is the first step to finding out whether bruxism is affecting your teeth and jaw, and what can be done about it. Our team at Dentists @ Canning Vale can assess your bite, examine wear patterns, and discuss the options that are right for your situation.
