Teeth grinding, also known as bruxism, is a common dental condition that affects many individuals, often without them even realising it. This article will explore the signs of grinding teeth, shed light on why it occurs, its impact during sleep, susceptibility factors, and effective treatment options.

Recognising Teeth Grinding

  • Audible Grinding Noises: One of the most noticeable signs of teeth grinding is the sound it produces. Bed partners or family members may hear a grating or grinding noise when you sleep.
  • Morning Headaches: Frequent headaches upon waking can be an indicator of nighttime teeth grinding. The clenching and grinding can cause muscle tension and discomfort in the head and neck area.
  • signs of grinding teeth pain melbourneJaw Pain Or Soreness: Bruxism often leads to jaw pain, facial soreness, or earaches. These symptoms result from the continuous strain on the jaw muscles.
  • Tooth Sensitivity: Grinding can wear down the protective enamel of the teeth, making them more sensitive to hot and cold temperatures and certain foods.
  • Tooth Damage: Over time, teeth grinding can lead to tooth damage such as fractures, chips, or even loose teeth. This might lead to the need for dental treatment.
  • Facial Pain: Teeth grinding can also result in pain and discomfort around the jaw and face, particularly in the area of the temporomandibular joint (TMJ), which joins the jaw to the skull.
  • Sensitive Teeth: As the enamel wears down, teeth may become more sensitive to touch and pressure.
  • Jaw Locking: In severe cases, teeth grinding can cause the jaw to lock momentarily, making it challenging to open or close the mouth.
  • Chewed Objects: Some individuals may clench their jaw and grind their teeth even while awake, often without realising it. This can lead to the unintentional chewing of objects like pens or pencils.
  • Unexplained Tooth Wear: Dentists often identify teeth grinding by observing unusual patterns of tooth wear during regular dental check-ups.

Understanding these signs of tooth grinding is crucial for early detection and intervention. If you or someone you know experiences these symptoms, it’s important to explore the causes and seek appropriate treatment to prevent further dental complications and discomfort.

Why People Grind Teeth

Understanding why people grind their teeth is a key aspect of addressing this common dental condition. While the exact causes can vary from person to person, several factors contribute to teeth grinding:

Psychological Factors

Emotional factors, including anger, frustration, or suppressed emotions, can contribute to bruxism, particularly during awake hours.

Misaligned Teeth

Irregularities in tooth alignment or bite can contribute to bruxism. The grinding may occur as an unconscious effort to correct the bite or relieve discomfort.

Unhealthy Habits

Certain lifestyle choices, such as excessive alcohol consumption, cigarette smoking, and recreational drug use, can increase the risk of teeth grinding.

It’s crucial to remember that there may be several contributing factors to teeth grinding, and a person may suffer from more than one of them. Determining the root problems is essential to creating a successful treatment strategy.

What Happens When You Grind Your Teeth During Sleep?

Teeth grinding during sleep, known as sleep bruxism, can have various consequences that extend beyond just dental issues. Understanding what happens during sleep bruxism is essential for recognising its impact on overall health.

Dental Damage

The continuous grinding and clenching of teeth can result in significant dental damage over time. This includes tooth wear, fractures, chips, and even loosening of teeth. Such damage often necessitates dental treatment, including restorative procedures.

Temporomandibular Joint (TMJ) Discomfort

The temporomandibular joint (TMJ) is impacted by sleep bruxism, which causes jaw pain and discomfort. Temporomandibular joint disease (TMD) may arise from this, necessitating more sophisticated medical care.

Facial Pain

The strain placed on jaw muscles during sleep bruxism can lead to facial pain and discomfort, including headaches and earaches.

Disrupted Sleep

Sleep grinding can disrupt normal sleep patterns, causing frequent awakenings throughout the night. This can result in inadequate or poor-quality sleep, leading to daytime fatigue and irritability.

Sensitive Teeth

The enamel erosion caused by bruxism can lead to tooth sensitivity, making hot or cold foods and beverages painful to consume.

Risk of Obstructive Sleep Apnoea (OSA)

Sleep bruxism is often associated with OSA, a sleep disorder characterised by repeated pauses in breathing during sleep. Individuals with sleep bruxism are at an increased risk of developing OSA.

Reduced Quality Of Life

The combined impact of dental issues, facial pain, disrupted sleep, and potential health risks can significantly reduce an individual’s overall quality of life.

Dental Treatment Costs

Addressing the dental damage caused by bruxism can be costly, as it may require procedures like dental crowns, veneers, or orthodontic treatment.

Understanding the consequences of sleep bruxism underscores the importance of early diagnosis and treatment.

Who Might Be More Susceptible To Sleep Grinding, And What Are The Risks Involved?



Teeth grinding, particularly during sleep (known as sleep bruxism), can affect individuals of all ages. However, certain factors and conditions may make some people more susceptible to this habit. Understanding who is at a higher risk can help with early recognition and intervention.

Here are some factors that may increase the susceptibility to sleep grinding and the associated risks:

  • Stress And Anxiety: Individuals experiencing high levels of stress or anxiety are more prone to teeth grinding. The clenching and grinding of teeth may serve as a subconscious response to emotional tension.
    • Risks: Stress-related teeth grinding can lead to significant dental damage, jaw pain, and an overall reduction in well-being.
  • Sleep Disorders: OSA and other sleep problems are frequently linked to sleep bruxism. OSA involves interrupted breathing during sleep and may trigger bruxism episodes.
    • Risks: Individuals with both sleep bruxism and OSA may face an increased risk of disrupted sleep patterns, daytime fatigue, and serious health issues associated with OSA.
  • Lifestyle Factors: Lifestyle choices, such as excessive alcohol consumption, smoking, or recreational drug use, may contribute to teeth grinding.
    • Risks: These factors can exacerbate bruxism and may lead to severe dental complications and overall health risks associated with substance abuse.
  • Medications: Certain drugs have been proven to be connected to teeth grinding, especially selective serotonin reuptake inhibitors (SSRIs).
    • Risks: Bruxism induced by medications may necessitate changes in treatment or additional measures to manage the condition.
  • Genetic Predisposition: A family history of bruxism may increase the likelihood of an individual developing this habit.
    • Risks: Genetic predisposition can make it challenging to prevent or control bruxism, highlighting the importance of early intervention and management.
  • Children and Adolescents: Bruxism is relatively common among children and adolescents, with many outgrowing the habit as they age.
    • Risks: While childhood bruxism often resolves on its own, it can still lead to dental issues and discomfort during the developmental years.

It is crucial to acknowledge that teeth grinding can affect anyone, at any age or from any background. To minimise related dangers and ensure early action, it is important to identify the underlying causes and risk factors.

If you suspect you or a loved one may be at risk of sleep grinding, consulting a healthcare provider or dentist can provide valuable insights and guidance on appropriate measures to address the condition and mitigate potential risks.

How To Treat Teeth Grinding

Treating teeth grinding, or bruxism, involves addressing the underlying causes and alleviating its symptoms.

There are various approaches to managing and treating this condition effectively:

  • Dental Interventions:
    • signs of grinding teeth mouthguard melbourneMouthguards and Splints: Dental professionals often recommend custom-fitted mouthguards or splints to protect teeth from the effects of grinding. These devices create a barrier between the upper and lower teeth, preventing damage.
    • Orthodontic Treatment: In cases where misaligned teeth contribute to bruxism, orthodontic treatment or dental adjustments may be recommended to correct the bite.
    • Restorative Dentistry: Dental damage caused by bruxism, such as fractures or chips, can be repaired through restorative procedures like dental crowns or veneers.
  • Behavioural Approaches:
    • Stress Management: Reducing stress and anxiety can be a crucial step in addressing teeth grinding. Stress management methods include breathing exercises, meditation, and counselling.
    • Cognitive Behavioural Therapy (CBT): By addressing the psychological and emotional aspects that lead to tooth grinding, CBT is a useful treatment for bruxism.
    • Biofeedback: This technique involves monitoring and controlling muscle activity to reduce grinding. It can be learned through biofeedback therapy.
    • Limiting Stimulants: Reducing or eliminating the consumption of caffeine, alcohol, and tobacco can help alleviate bruxism in some cases.
  • Medications:
    • Muscle Relaxants: Muscle relaxants are sometimes prescribed by medical professionals to treat bruxism-related jaw muscle stress.
    • Antidepressants: If bruxism is associated with tension or anxiety, a prescription for SSRIs may be necessary.
  • Lifestyle Adjustments:
    • Dietary Adjustments: Reduce the likelihood that your teeth may grind while you sleep by consuming less-chewable items, particularly in the evening.
    • Liquids: Maintaining adequate hydration may aid in muscular relaxation and lower the chance of bruxism.
    • Sleep hygiene: Developing sound sleeping practices might enhance the quality of your sleep and lessen the occurrence of grinding episodes.
  • Botox Injections: In some cases, healthcare providers may recommend Botox injections to relax the jaw muscles temporarily and reduce bruxism symptoms.
  • Continuous Monitoring: Regular dental check-ups can help monitor the condition and assess any dental damage or changes in bite that may require intervention.
  • Stress Reduction Techniques: Practising stress-reduction techniques such as yoga, meditation, and deep breathing exercises can help individuals manage bruxism triggered by stress.
  • Oral Hygiene: Good oral hygiene practices, including regular brushing and flossing, can help maintain dental health and prevent further damage caused by bruxism.

It’s important to note that treatment approaches may vary based on the severity of the condition and individual factors.

Consulting a dentist is crucial for an accurate diagnosis and developing an appropriate treatment plan. Addressing bruxism promptly can prevent dental complications and improve overall well-being.
