Teeth Grinding (Bruxism) Treatment

Bruxism is the medical term for the unconscious habit of grinding, clenching, or gnashing the teeth. It commonly occurs during sleep — known as sleep bruxism — though some people also grind or clench during the day, often without realising it. Bruxism affects people of all ages and can cause damage to the teeth, jaw muscles, and temporomandibular joints over time if left unmanaged. It is estimated that up to 30% of people experience bruxism at some point in their lives.

Temporomandibular Joint Disorder, commonly referred to as TMD or TMJ disorder, is a condition affecting the jaw joints and surrounding muscles that control chewing and jaw movement. Teeth grinding is one of the most common causes and aggravating factors of TMD, as the excessive and repetitive forces generated during grinding place significant strain on the temporomandibular joints and the muscles that support them. The two conditions frequently occur together — bruxism can trigger or worsen TMD, and an already dysfunctional jaw joint can make grinding more damaging. At Doncaster Dental, both conditions are assessed and managed together as part of a comprehensive treatment approach.

Because bruxism commonly occurs during sleep, many people are unaware they grind their teeth until symptoms develop or a partner reports the sound of grinding overnight. Common signs and symptoms include a dull morning headache, jaw soreness or stiffness on waking, facial muscle pain, earache or pain near the ear, tooth sensitivity, flattened, chipped, or worn-down teeth, and damage to the inside of the cheeks from clenching. Your dentist at Doncaster Dental can often identify signs of bruxism during a routine check-up by examining the wear patterns on your teeth.

The exact causes of bruxism are not fully understood, but it is associated with psychological stress and anxiety — many people grind their teeth during periods of heightened pressure at work or in their personal lives. Sleep disorders, particularly obstructive sleep apnoea, are also closely linked to sleep bruxism. Other contributing factors include certain medications such as antidepressants, caffeine and alcohol consumption, a misaligned bite, and genetic predisposition. Addressing the underlying cause, where possible, is an important part of managing bruxism alongside dental treatment at Doncaster Dental.

Untreated bruxism can cause extensive and progressive damage to the teeth and jaw. The forces generated during sleep grinding are greater than those produced during normal chewing, and sustained over time they can wear down tooth enamel, flatten or chip teeth, crack existing fillings or crowns, cause increased tooth sensitivity, lead to chronic jaw pain and headaches, and result in permanent damage to the temporomandibular joints. Once tooth structure is lost through grinding, it needs to be restored with fillings, crowns, or other dental work — making early management at Doncaster Dental far more cost-effective than waiting until damage is severe.

Doncaster Dental diagnoses bruxism through a combination of a clinical examination and your reported symptoms. During a check-up, the dentist examines your teeth for characteristic wear patterns, assesses the condition of your jaw muscles and joints, and may take X-rays to evaluate the extent of any damage. A detailed history of your symptoms — including the timing of headaches, jaw pain, and any sleep disturbances — helps build a full picture of your condition and guides the treatment approach.

Treatment at Doncaster Dental takes a comprehensive approach that addresses both the symptoms and contributing factors. A custom-fitted nightguard is the primary dental treatment — worn during sleep, it creates a protective barrier between the upper and lower teeth to absorb grinding forces and prevent further wear. Where stress or anxiety is a contributing factor, stress management guidance and referral to appropriate allied health professionals may be recommended. Physical therapy referrals can help reduce jaw muscle tension and TMD-related pain. Where the bite is misaligned and contributing to grinding, corrective dental procedures to restore damaged teeth and improve bite alignment may also be recommended. Your dentist will develop a personalised treatment plan based on your specific situation.

Teeth grinding is relatively common in children, particularly in the primary (baby) teeth stage, and often resolves on its own as the child grows and their teeth and bite develop. However, persistent grinding in children — especially if accompanied by headaches, jaw pain, disturbed sleep, or tooth wear — should be assessed by a dentist. Doncaster Dental welcomes children for assessment and can advise on whether any intervention is needed or whether a watch-and-wait approach is more appropriate.

Yes — psychological stress and anxiety are among the commonly identified triggers for bruxism. Many people begin grinding their teeth or notice a worsening of existing grinding during periods of heightened stress, such as major life changes, work pressure, or poor sleep. Managing stress through exercise, relaxation techniques, mindfulness, and where appropriate, psychological support, can help reduce the frequency and severity of bruxism. A custom nightguard from Doncaster Dental protects the teeth in the meantime, while the broader treatment plan addresses the contributing factors.
