Teeth grinding, clinically known as bruxism, affects approximately 1 in 3 Australian adults during sleep. Many people grind their teeth nightly without realising it until a dentist identifies wear patterns or a partner reports the sound. East Adelaide Dental Studio in Glenside provides comprehensive bruxism diagnosis and treatment for patients across Adelaide, including Burnside, Kensington, Norwood, Toorak Gardens, Dulwich, Rose Park, Linden Park, Leabrook and the Adelaide Hills. Dr Arthur Shizas, Dr Serena Vi, Dr Daniel Yeu and Dr Pierre Kieu offer custom night splints, preventive care and restorative treatment to stop grinding damage before it compromises your oral health.

What Is Teeth Grinding (Bruxism)?

Bruxism is the involuntary clenching, grinding or gnashing of teeth that occurs outside normal chewing and swallowing. The condition presents in two distinct forms: sleep bruxism and awake bruxism.

Sleep bruxism, also called nocturnal bruxism, happens during the night. It typically occurs during lighter sleep stages or during micro-arousals. A person with sleep bruxism generates grinding forces far exceeding normal chewing pressure, often without any conscious awareness. According to the Australian Sleep Association, approximately 1 in 3 adults grind their teeth at night. Of those, 5 to 8 percent experience severe, frequent grinding that causes significant dental damage.

Awake bruxism occurs during waking hours. People who clench or grind while awake often do so in response to stress, concentration or anxiety. The jaw tightens, teeth press together and the masseter muscles engage repeatedly. Unlike sleep bruxism, awake bruxism may be partially controllable once the person becomes aware of the habit.

Both forms place excessive force on teeth, jaw muscles and the temporomandibular joint (TMJ). Over time, this force causes measurable structural damage to enamel, dental restorations and facial musculature. East Adelaide Dental Studio diagnoses and treats both sleep and awake bruxism for patients across Adelaide and the Adelaide Hills.

What Are the Symptoms of Teeth Grinding?

Teeth grinding produces 8 primary symptoms that affect the teeth, jaw muscles, facial nerves and sleep quality. Many patients do not recognise these symptoms as connected to bruxism until a dentist identifies the underlying cause during a routine examination.

The 8 symptoms of teeth grinding include:

1. Morning headaches. Dull, tension-type headaches concentrated in the temporal region on the sides of the head upon waking. These headaches result from sustained masseter and temporalis muscle contraction overnight.
2. Jaw pain or stiffness. Pain or tenderness in the jaw joints and muscles, most noticeable in the morning. The masseter muscle may feel enlarged or firm to the touch.
3. Worn, flattened or chipped teeth. Teeth gradually lose their natural contours, developing smooth, flat surfaces or microscopic cracks. Canines and front teeth show wear first.
4. Increased tooth sensitivity. As enamel wears away, the underlying dentine becomes exposed. This causes sharp sensitivity to hot, cold and sweet stimuli.
5. Earache. Referred pain from the TMJ radiates to the ear canal, creating an ache that mimics an ear infection but originates from jaw joint inflammation.
6. Facial muscle fatigue. The muscles of mastication, including the masseter, temporalis and medial pterygoid, feel tired or overworked. This fatigue is particularly noticeable when chewing firm foods.
7. Sleep disruption for bed partners. Grinding sounds can reach 40 to 60 decibels, comparable to normal conversation volume. This frequently disturbs a sleeping partner.
8. Indentations on the tongue or cheek. The tongue and inner cheeks may develop scalloped edges or white lines called linea alba from repeated pressure against the teeth.

Many patients first learn they grind their teeth when a partner mentions the noise or when a dentist identifies characteristic wear patterns called attrition facets during a regular check-up and professional clean. By the time symptoms appear, grinding has often been occurring for months or years.

What Causes Teeth Grinding?

Teeth grinding has 8 recognised causes spanning psychological, physiological, lifestyle and pharmacological factors. The primary cause in most adult patients is stress and anxiety, which increases muscle tension throughout the body, including the jaw.

The 8 causes of teeth grinding are:

1. Stress and anxiety. The leading cause of bruxism. Heightened stress increases involuntary muscle tension in the jaw. Research published in the Journal of Oral Rehabilitation in 2020 found that stress-related bruxism cases increased by 15 percent during periods of heightened collective anxiety.
2. Sleep disorders. Obstructive sleep apnoea, snoring and other sleep-disordered breathing conditions trigger grinding as the body attempts to reopen the airway. Roughly 50 percent of sleep apnoea patients also grind their teeth.
3. Malocclusion (misaligned bite). When upper and lower teeth do not meet evenly, the jaw muscles work harder to find a comfortable position, increasing grinding behaviour.
4. Caffeine consumption. High caffeine intake, particularly in the afternoon and evening, stimulates the central nervous system and increases muscle activity during sleep.
5. Alcohol consumption. Alcohol disrupts normal sleep architecture, increasing the frequency of micro-arousals during which grinding episodes occur.
6. Smoking. Nicotine is a stimulant that increases muscle activity and disrupts sleep patterns. Smokers are approximately twice as likely to grind their teeth as non-smokers.
7. Certain medications. Selective serotonin reuptake inhibitors (SSRIs), antipsychotics and some antidepressants list bruxism as a documented side effect.
8. Acid reflux and neurological conditions. Gastroesophageal reflux disease (GERD), Parkinson disease and other neurological conditions can trigger or worsen grinding through complex neural pathways.

Patients with sleep apnoea who also grind their teeth benefit from dual treatment addressing both conditions. East Adelaide Dental Studio coordinates with sleep physicians to ensure comprehensive sleep apnoea treatment alongside bruxism management.

How Does Teeth Grinding Damage Your Teeth?

Teeth grinding causes 7 types of progressive damage to teeth, dental restorations and the temporomandibular joint. The damage accumulates slowly, which is why many patients underestimate the severity until a fracture or severe wear becomes visible.

The 7 types of teeth grinding damage include:

1. Enamel wear (attrition). Enamel is the hardest substance in the human body, but it gradually wears away under repeated grinding pressure. Once lost, enamel does not regenerate.
2. Tooth fractures and cracks. Sustained grinding pressure creates hairline cracks that deepen over time. Cracks eventually reach the pulp, causing pain and requiring root canal treatment or extraction.
3. Loose teeth. The periodontal ligament that anchors each tooth stretches under repeated grinding forces. Over time, teeth develop measurable mobility.
4. Damaged fillings and crowns. Existing dental restorations fracture or dislodge under grinding pressure. A cracked tooth-coloured filling or broken dental crown requires replacement to prevent further damage.
5. TMJ disorders. The temporomandibular joint suffers inflammation, clicking, locking and limited opening. Chronic TMJ dysfunction leads to degenerative arthritis in the jaw joint.
6. Bone loss around teeth. The excessive force transmitted through teeth to the surrounding alveolar bone accelerates bone loss, particularly in patients with existing periodontal disease.
7. Changes to facial appearance. As teeth wear down and shorten, the lower face height collapses. This creates a sunken, aged appearance and deepens the folds around the mouth.

According to the Australian Sleep Association, nocturnal grinding can exert up to 250 pounds of pressure per square inch on the teeth. Normal chewing generates approximately 70 pounds per square inch. Grinding delivers more than three times the force of normal chewing, sustained for hours each night.

How Is Bruxism Diagnosed?

Bruxism diagnosis involves several clinical assessments performed during a comprehensive dental examination. Dr Arthur Shizas, Dr Serena Vi, Dr Daniel Yeun and Dr Pierre Kieu at East Adelaide Dental Studio use a systematic approach to identify grinding and assess the extent of any damage.

The diagnostic process may include:

1. Dental examination for wear patterns: The dentist examines the teeth for flattened or polished areas on the biting surfaces where upper and lower teeth may have ground against each other.
2. Patient symptom report: The dentist asks about morning headaches, jaw stiffness, tooth sensitivity and awareness of clenching during the day.
3. Partner report of grinding sounds: Information from a partner may help because patients are often unaware that they grind their teeth while sleeping.
4. Jaw-muscle assessment: The dentist checks the masseter and temporalis muscles for tenderness, enlargement or firmness.
5. TMJ assessment: The temporomandibular joints are assessed for clicking, restricted opening, deviation and discomfort during movement.
6. Dental X-rays: Where clinically appropriate, X-rays may be used to assess the teeth, supporting bone and other signs of grinding-related damage.
7. Sleep-study referral: If sleep apnoea or another sleep-related condition is suspected, the patient may be referred to an appropriate medical or sleep-health practitioner for further assessment.

Early diagnosis can limit further wear, which often means simpler and less costly treatment. Patients in Glenside, Burnside, Kensington, Norwood and surrounding suburbs can book a bruxism assessment by calling (08) 8379 3529 or using our contact page.

What Are the Treatment Options for Teeth Grinding?

Bruxism treatment involves 7 evidence-based options ranging from preventive interventions to advanced restorative procedures. The primary treatment for most patients is a custom night splint, which protects the teeth from grinding forces during sleep.

The 7 treatment options for teeth grinding are:

1. Custom night splint (occlusal splint). A precisely fitted acrylic appliance worn during sleep that separates the upper and lower teeth. It prevents enamel-to-enamel contact and reduces grinding force. East Adelaide Dental Studio fabricates custom-fitted night splints using detailed impressions of your teeth for an exact, comfortable fit.
2. Stress management. Since stress is the primary cause of bruxism, cognitive behavioural therapy, meditation, regular exercise and counselling reduce grinding frequency and intensity.
3. Behavioural therapy (biofeedback). Electromyography biofeedback devices train the jaw muscles to relax by providing real-time feedback on muscle tension. This helps patients unlearn the grinding pattern.
4. Muscle relaxant medication. In severe cases, a medical practitioner may prescribe short-term muscle relaxants to reduce nocturnal jaw muscle activity. This approach addresses symptoms rather than the underlying cause.
5. Botox injections. Botulinum toxin injected into the masseter muscle reduces its contractile strength for 3 to 6 months. This treatment suits patients with severe grinding who do not respond to night splints.
6. Bite correction. When malocclusion contributes to grinding, correcting the bite through orthodontic treatment using clear aligners or selective reshaping of interfering tooth surfaces reduces grinding triggers.
7. Repairing damaged teeth. Teeth already damaged by grinding require restoration. Treatment options include tooth-coloured fillings for minor wear, dental crowns for extensively worn or cracked teeth, porcelain veneers for front teeth with cosmetic damage and tooth extraction for teeth that cannot be saved.

The custom night splint remains the cornerstone of bruxism treatment. It does not stop the grinding reflex, but it absorbs the force and prevents further damage to teeth, fillings, crowns and the TMJ. Wearing a night splint nightly is significantly less expensive than restoring multiple damaged teeth over time.

What Are the Costs of Bruxism Treatment in Adelaide?

The cost of bruxism treatment in Adelaide varies based on the type and extent of treatment required. The primary investment for most patients is a custom night splint, followed by any restorative work needed for teeth already damaged by grinding.

The table below summarises the main cost categories for bruxism treatment at East Adelaide Dental Studio:

A custom night splint is a preventive investment that costs significantly less than repairing or replacing multiple damaged teeth. A single cracked tooth requiring a crown costs more than a night splint designed to protect all teeth. Patients who delay splint therapy often face treatment plans involving 4 to 8 crowns, fillings or root canals, totalling thousands of dollars.

East Adelaide Dental Studio is a Bupa Members Choice and HCF Members Choice preferred provider. Patients with these health funds receive higher rebates on bruxism treatment. The practice also offers Denticare payment plans and Afterpay, allowing patients to spread the cost of treatment over manageable instalments.

What Happens If You Leave Teeth Grinding Untreated?

Untreated teeth grinding causes 6 progressive consequences that worsen over time. The damage is cumulative and irreversible, meaning every month of grinding without protection adds to the total damage your teeth sustain.

The 6 consequences of untreated bruxism are:

1. Progressive enamel loss. Enamel continues to wear away until the softer dentine layer underneath is exposed. Dentine wears approximately 8 times faster than enamel, accelerating the rate of tooth destruction once exposed.
2. Multiple cracked teeth. Hairline cracks deepen and multiply. Eventually, cracks reach the dental pulp, causing infection, abscess and intense pain. Cracked teeth require root canal treatment and dental crowns, or extraction if the crack extends below the gumline.
3. Tooth loss. Severe grinding eventually loosens teeth beyond the point where they can be saved. Tooth extraction becomes the only option, followed by expensive replacement options such as implants or bridges.
4. TMJ arthritis. Chronic inflammation of the temporomandibular joint leads to degenerative joint disease. The jaw joint develops arthritis, causing permanent pain, clicking and limited movement.
5. Chronic facial pain and headaches. The muscles of mastication remain in a state of chronic tension, producing daily headaches, facial soreness and neck pain that reduce quality of life.
6. Full-mouth reconstruction. When grinding has damaged most or all teeth, the only solution is a full-mouth reconstruction involving multiple crowns, veneers and potentially implants. This treatment costs tens of thousands of dollars and requires many appointments over several months.

A custom night splint worn nightly prevents these consequences by absorbing grinding forces and protecting tooth structure. The investment in a splint at the first sign of grinding saves patients from extensive, expensive and time-consuming restorative treatment later.

How Can You Prevent Teeth Grinding?

Teeth grinding prevention involves 7 practical strategies that reduce grinding frequency, intensity and damage. While not all causes of bruxism can be eliminated, these measures significantly reduce the impact on your teeth and jaw.

The 7 prevention strategies include:

1. Manage stress. Regular exercise, meditation, yoga, counselling and cognitive behavioural therapy reduce the muscle tension that drives grinding. Aim for at least 30 minutes of moderate exercise daily.
2. Avoid caffeine before bed. Stop consuming coffee, tea, energy drinks and chocolate at least 6 hours before sleep. Caffeine has a half-life of 5 to 6 hours and keeps the nervous system stimulated.
3. Avoid alcohol before bed. Alcohol disrupts sleep stages and increases the frequency of micro-arousals during which grinding occurs.
4. Establish a relaxing bedtime routine. Read, take a warm bath, practise gentle stretching or listen to calming music in the hour before sleep. A consistent routine signals the nervous system to wind down.
5. Stop chewing gum. Gum chewing conditions the jaw muscles to stay engaged, increasing the likelihood of nocturnal clenching. Replace gum with sugar-free mints if needed.
6. Practise jaw relaxation exercises. Place the tip of your tongue on the roof of your mouth behind your front teeth and allow your jaw to drop open slightly. Hold this position for 5 minutes, 3 times daily.
7. Wear a custom night splint. The most effective prevention against grinding damage is a professionally fitted night splint worn every night. East Adelaide Dental Studio provides custom-fitted night splints made to the exact contours of your teeth.

Patients who combine stress management with a custom night splint achieve the best outcomes. The splint provides physical protection while stress reduction targets the underlying cause. Book a consultation at East Adelaide Dental Studio in Glenside to discuss a personalised prevention plan.

Frequently Asked Questions

How do I know if I grind my teeth at night?

The most reliable indicators of nocturnal teeth grinding are morning headaches, jaw stiffness upon waking, worn or flattened teeth and increased tooth sensitivity. Many people only discover they grind their teeth when a partner reports the sound or when a dentist identifies wear patterns during a regular check-up and professional clean. If you wake with a sore jaw or a dull headache concentrated in your temples, schedule a bruxism assessment at East Adelaide Dental Studio.

Can teeth grinding be cured?

Teeth grinding can be managed and its effects eliminated, but the grinding reflex itself is not always curable. Stress-related bruxism often improves when the underlying stress is addressed. Sleep-related bruxism linked to sleep apnoea improves with appropriate sleep apnoea treatment. A custom night splint prevents grinding damage regardless of whether the grinding reflex continues, making it the most reliable long-term solution.

How much does a night guard cost in Adelaide?

A custom night splint in Adelaide costs between $600 and $900 depending on the complexity of your bite and the materials used. East Adelaide Dental Studio is a Bupa Members Choice and HCF Members Choice provider, meaning eligible patients receive health fund rebates. Denticare payment plans and Afterpay are available to spread the cost. A night splint costs significantly less than the restorative treatment needed for teeth damaged by untreated grinding.

Can teeth grinding cause tooth loss?

Yes, severe untreated teeth grinding can cause tooth loss through progressive loosening from stretched periodontal ligaments, deep cracks reaching the tooth root and advanced bone loss around affected teeth. Teeth that become loose or develop cracks below the gumline may require tooth extraction. Wearing a custom night splint prevents the forces that lead to tooth loss, preserving your natural teeth long-term.

Is teeth grinding related to stress?

Yes, stress is the primary cause of bruxism in adults. Heightened stress increases involuntary muscle tension throughout the body, including the muscles that control the jaw. Research published in the Journal of Oral Rehabilitation in 2020 linked periods of increased collective stress to a 15 percent rise in bruxism cases. Managing stress through exercise, counselling, meditation and relaxation techniques directly reduces grinding frequency and intensity. East Adelaide Dental Studio can assess your grinding and recommend a custom-fitted night splint to protect your teeth while you address stress factors.

How long do I need to wear a night splint?

Most patients wear a custom night splint indefinitely, every night, to protect their teeth from ongoing grinding forces. The grinding reflex is a neurological pattern that does not simply disappear. A well-maintained night splint lasts 3 to 5 years before requiring replacement. Patients who address underlying causes such as stress or sleep apnoea may experience reduced grinding intensity, but continued splint use ensures teeth remain protected. East Adelaide Dental Studio offers flexible payment options to help manage the cost of ongoing splint therapy.
