How to Stop Teeth Grinding and Jaw Clenching (Bruxism): Causes, Symptoms and Treatments
Bruxism, the clinical term for teeth grinding and jaw clenching, affects a significant proportion of the population and often goes undiagnosed for years. Many people who grind their teeth in sleep are entirely unaware it is happening until a partner mentions the sound, or a dentist points out the wear on their teeth. For others, the experience is one of constant daytime tension, with a clenched jaw that tightens in response to stress or concentration without any conscious awareness.
Whether you are dealing with grinding teeth at night, persistent jaw clenching during the day, or both, understanding the condition is the first step toward finding a solution that actually works. At Aesthetica HQ, Sydney's trusted cosmetic clinic, we provide clinical bruxism treatment that addresses the root muscular cause to provide real, lasting relief.
What Is Bruxism?
Bruxism is a condition characterised by the involuntary grinding, clenching, or gnashing of teeth. It occurs in two primary forms:
Sleep Bruxism refers to teeth grinding during sleep. It is classified as a sleep-related movement disorder and is often associated with other sleep disturbances. Because it occurs unconsciously, many people with sleep bruxism are unaware they have it until symptoms accumulate.
Awake Bruxism refers to jaw clenching or teeth grinding during waking hours, typically during periods of concentration, stress, or tension. Unlike sleep bruxism, awake bruxism often does not involve actual grinding but presents instead as a persistent clenching of the jaw.
Both forms can occur independently or together in the same individual.
Bruxism Symptoms: How to Tell If You Grind Your Teeth
Bruxism symptoms vary depending on severity and whether grinding occurs primarily at night or during the day. Common signs include:
Waking up with jaw pain, facial soreness, or a dull headache
Tooth sensitivity or pain, particularly in the morning
Worn, flattened, chipped, or cracked teeth
A visibly enlarged or squared jawline caused by overdeveloped masseter muscles
Pain or stiffness in the jaw, neck, or shoulders
Disrupted sleep or reported grinding sounds from a partner
Persistent jaw clenching when concentrating, working, or driving
Earache or a sensation of fullness in the ears
Tooth pain from grinding that worsens over time
If you recognise several of these symptoms, it is worth seeking an assessment, as untreated bruxism can cause progressive dental damage and chronic jaw pain.
What Causes Teeth Grinding in Sleep?
The exact cause of bruxism is not fully understood, but research points to a combination of psychological, physiological, and lifestyle factors. The most commonly identified contributors include:
Stress and Anxiety Emotional stress is widely considered the most significant trigger for both sleep and awake bruxism. The jaw muscles contract as part of the body's stress response, and in people prone to bruxism, this tension carries over into sleep or becomes a habitual daytime behaviour.
Sleep Disorders Sleep bruxism is associated with other sleep-related conditions including sleep apnoea, snoring, and disrupted sleep architecture. Research suggests that grinding episodes often coincide with arousal events during sleep, making sleep quality closely linked to bruxism severity.
Medications and Substances Certain medications, particularly some antidepressants, as well as caffeine, alcohol, and recreational substances, are associated with an increased risk of bruxism. If you have noticed teeth grinding coinciding with a change in medication, this is worth discussing with your prescribing doctor.
Personality and Lifestyle Individuals with competitive, hyperactive, or highly driven personalities appear to have a higher incidence of bruxism. Occupational stress and high-pressure work environments are frequently reported as contributing factors.
Genetics Bruxism tends to run in families, suggesting a genetic predisposition in some individuals.
Misaligned Bite Dental occlusion issues, where the upper and lower teeth do not align correctly, can contribute to grinding. However, this is considered a less significant factor than psychological and neurological contributors in current research.
How to Stop Grinding Teeth: At-Home Strategies
For mild bruxism or as a complement to professional treatment, the following approaches can help reduce the frequency and impact of teeth grinding and jaw clenching.
Stress Management Because stress is the primary driver of bruxism for most people, any approach that meaningfully reduces stress levels can help. Regular physical exercise, adequate sleep, mindfulness practices, and psychological support such as cognitive behavioural therapy (CBT) have all been shown to reduce bruxism frequency in clinical settings.
Jaw Exercises and Stretching Gentle jaw exercises and stretching can help release tension in the masseter and surrounding muscles. A simple approach is to place your tongue between your teeth (not biting down) to encourage the jaw to relax, or to practice slow, wide yawning motions to stretch the jaw muscles. A physiotherapist or dentist can guide you through a more structured programme if jaw pain is significant.
Reducing Caffeine and Alcohol Both caffeine and alcohol are associated with more frequent and intense bruxism episodes. Reducing intake, particularly in the hours before sleep, can make a noticeable difference to the severity of grinding teeth at night.
Heat Application Applying a warm compress to the jaw before sleep can help relax the masseter muscles and reduce the likelihood of clenching overnight. This is a simple, low-cost strategy that many people find helpful for managing jaw pain from clenching.
Awareness and Habit Correction for Daytime Clenching For awake bruxism, building awareness is central to managing the habit. Setting periodic reminders throughout the day to check whether your jaw is relaxed, your lips are lightly closed, and your teeth are slightly apart (the resting position) can help interrupt the clenching cycle over time.
Dental Guards for Teeth Grinding
A dental guard, also known as an occlusal splint or night guard, is one of the most commonly recommended treatments for bruxism, particularly sleep bruxism. Worn over the upper or lower teeth during sleep, a dental guard works by creating a physical barrier between the upper and lower teeth, absorbing the force of grinding and preventing direct tooth-on-tooth contact.
Dental guards do not stop the grinding behaviour itself but protect the teeth and jaw structures from the damage that repeated grinding causes. For many people, a well-fitted guard also provides some relief from jaw pain and morning headaches.
Custom-fitted dental guards made by a dentist offer significantly better comfort, protection, and durability than over-the-counter options, which tend to be bulkier and less precisely fitted to individual anatomy.
If you are already experiencing tooth wear, sensitivity, or jaw pain from clenching, speaking to a dentist about a custom guard is a sensible early step.
Clinical Bruxism Treatment: Addressing the Muscle Directly
While dental guards and lifestyle changes manage the symptoms and consequences of bruxism, they do not address the underlying muscular activity driving the condition. For people with moderate to severe bruxism, persistent jaw pain, or a visibly enlarged jawline caused by hypertrophied masseter muscles, a clinical approach that targets the muscles themselves can provide significantly more effective and longer-lasting relief.
At Aesthetica HQ, our Bruxism (Teeth Clenching/Grinding) Treatment uses a therapeutic muscle-relaxing treatment administered directly into the masseter muscles. The masseter is the large muscle on either side of the jaw responsible for the chewing action. In people with bruxism, these muscles are often overactive and overdeveloped, generating significant force during grinding and clenching episodes.
By introducing a precise, clinically measured amount of a muscle-relaxing agent into the masseter, the treatment reduces the intensity of involuntary muscle contractions without affecting normal jaw function such as speaking, eating, or yawning. The masseter is still able to perform all of its necessary functions; it simply cannot generate the excessive, damaging force associated with bruxism.
What to expect from treatment:
Results typically become apparent within seven to fourteen days following treatment, with the full effect establishing over the following two weeks. Clients commonly report a significant reduction in jaw soreness, morning headaches, tooth sensitivity, and the general tension associated with persistent jaw clenching. For those with a visibly enlarged jawline caused by masseter hypertrophy, a gradual slimming and softening of the lower face is also a common secondary benefit of treatment.
Each treatment session takes approximately fifteen to thirty minutes and requires no downtime. A thorough consultation is conducted prior to treatment to assess suitability, discuss your symptoms, and confirm the appropriate treatment plan for your anatomy and goals.
The effects of the treatment generally last three to four months. With repeated treatment cycles, many clients find that the masseter muscles gradually reduce in both size and activity, potentially extending the intervals between sessions over time.

How I Cured My Bruxism: What Actually Works Long-Term
Many people searching for a bruxism cure are looking for a single, definitive solution. The reality is that the most effective long-term management of bruxism typically involves a combination of approaches rather than any one standalone fix.
For the majority of people, a combination of the following provides the best outcomes:
Addressing the stress and psychological drivers through lifestyle changes, therapy, or stress management practices reduces the frequency of both sleep and awake bruxism over time.
A well-fitted dental guard protects teeth and structures from ongoing damage while other strategies take effect.
Periodic clinical muscle-relaxing treatment provides direct relief by reducing the force and intensity of grinding and clenching at the muscular level. For people with significant bruxism, this is often the most impactful single intervention.
Maintaining good sleep hygiene and addressing any underlying sleep disorders in conjunction with a GP or sleep specialist can reduce the frequency of sleep bruxism episodes.
No single approach is right for every person, and the most appropriate combination depends on the severity of your bruxism, its primary triggers, and your individual anatomy. A consultation with a qualified clinical professional is the best starting point for developing a personalised management plan.
Frequently Asked Questions
Why do I grind my teeth in my sleep if I am not aware of it? Sleep bruxism is an unconscious, involuntary behaviour. It occurs during specific stages of the sleep cycle and is not something most people can consciously control or prevent simply through awareness. This is why strategies that work during waking hours, such as habit reversal, are less effective for sleep bruxism, and why clinical treatment targeting the muscles directly is often more appropriate.
Can jaw clenching cause long-term damage? Yes. Chronic bruxism can cause progressive tooth wear, cracking, and sensitivity over time. It can also lead to temporomandibular joint (TMJ) dysfunction, chronic jaw and facial pain, headaches, and visible changes to the shape of the jaw from muscle hypertrophy. Early treatment is strongly advisable to prevent escalating damage.
Is bruxism related to TMJ? Bruxism and TMJ dysfunction frequently co-occur, and each can exacerbate the other. The excessive muscle force generated by grinding and clenching places significant stress on the temporomandibular joint, which can lead to pain, clicking, locking, or restricted jaw movement. Addressing bruxism is an important component of managing TMJ-related symptoms.
Will a dental guard stop my jaw from clenching? A dental guard protects teeth and structures from the physical damage of grinding but does not prevent the clenching behaviour itself. Many people find that wearing a guard reduces jaw soreness because the splint absorbs some of the force, but the underlying muscle activity continues. Clinical treatment that reduces masseter muscle activity addresses the behaviour more directly.
How long does clinical bruxism treatment last? The muscle-relaxing treatment administered at Aesthetica HQ typically produces results that last three to four months. Individual longevity varies depending on the strength of the masseter muscles, the severity of bruxism, and individual metabolism. Many clients find that with consistent treatment over time, the interval between sessions gradually extends as the masseter muscles reduce in activity.
Can bruxism be treated without a dentist? A dentist plays an important role in assessing dental damage, fitting occlusal guards, and ruling out bite-related contributors to bruxism. Clinical cosmetic treatments for bruxism, such as the muscle-relaxing injections offered at Aesthetica HQ, are a complementary approach administered by qualified cosmetic nurses. Both dental and clinical assessment may be appropriate depending on your individual circumstances.
