Bruxism, or teeth grinding: what it is and how it is treated
Reviewed by: Dr Lauras Smilgevičius, dentist
Bruxism is involuntary, often unconscious teeth grinding or forceful jaw clenching. It can happen during sleep or while you are awake. At first it may seem like a harmless habit, but over time it can affect your teeth, gums, jaw joints, facial muscles and quality of sleep. Many people do not realise they grind their teeth until a partner hears it at night, a dentist notices tooth wear, or symptoms such as jaw pain and headaches begin.
Studies suggest that sleep bruxism affects around 8 to 10 per cent of adults and 15 to 40 per cent of children, while awake bruxism is seen in almost one in four adults. Patients are often surprised by the force involved. During the night, the teeth can be exposed to pressure far beyond normal chewing. That hidden load is why bruxism is sometimes called the silent enemy of oral health.
At Miško Dental Clinic, we take this condition seriously. Bruxism is not only a mechanical dental problem. It often reflects stress, poor sleep, muscle tension, bite imbalance, or a combination of several factors. That is why we assess the whole person, not just the worn edges of the teeth.
What causes bruxism?
Bruxism is strongly linked with tension, stress and anxiety. It is a kind of body response that appears when conscious control switches off: at night, while the mind rests, the jaw muscles may stay on duty.
Current dental guidance, including NHS patient information, identifies stress and anxiety as the most common causes of teeth grinding in adults. Even so, there is rarely just one trigger. More often, several factors come together and slowly wear away the enamel, a little like water shaping stone.
ongoing stress, anxiety, depression or emotional burnout
an uneven bite or disturbed tooth contact
a missing tooth that has not been restored
poorly fitting crowns, fillings, bridges or dentures
neurological or inherited tendencies, as bruxism can run in families
sleep disorders, especially obstructive sleep apnoea
some medicines, particularly certain antidepressants
caffeine, alcohol, smoking and other stimulants
habits such as chewing gum, biting nails or chewing pens
Research also points to lifestyle patterns. People who drink large amounts of coffee every day appear to have a higher risk of bruxism. Sleep matters too. A significant proportion of people with sleep apnoea also grind their teeth at night, so loud snoring, choking episodes during sleep, or severe daytime tiredness should never be ignored.
“Bruxism rarely speaks with one voice. It is usually a choir: a little stress, a slightly uneven bite, poor sleep, tense muscles. Our job is to hear the whole choir, not only the loudest note.” - Dr Lauras Smilgevičius.
How can you recognise bruxism?
Because much of the grinding happens during sleep, many patients feel nothing at the time. The first signs often appear in the morning: a tight jaw, aching temples, neck tension, or tired facial muscles. Some people come to us thinking they have migraines or a neck problem, when the real starting point is night-time clenching.
worn, flattened chewing surfaces
chipped enamel, small cracks or microfractures
tooth sensitivity to cold, heat or sweet foods
headaches around the temples, especially in the morning
clicking, popping or stiffness in the jaw joint when opening the mouth
bite marks inside the cheeks or scalloped marks along the edge of the tongue
waking up tired despite sleeping for enough hours
a partner noticing grinding sounds at night
What are the possible consequences of bruxism?
Whether grinding is heavy or subtle, the effects build up slowly. First the enamel suffers, then the tooth structure, muscles and jaw joint. In time, bruxism can also affect facial proportions and everyday wellbeing. The table below shows how this progression often looks.
| Area | Early signs | Long-term consequences |
|---|---|---|
| Teeth | Enamel thinning, sensitivity | Shorter teeth, fractures, risk of pulp inflammation |
| Jaw joint | Clicking, morning stiffness | Painful TMJ disorder, difficulty opening the mouth |
| Muscles | Morning tightness in the cheeks and temples | Chronic jaw, neck and shoulder pain |
| Bite | Changed tooth contact | Loss of chewing height, altered facial proportions |
| General wellbeing | Morning tiredness | Headaches, poor sleep, low energy |
| Appearance | A duller smile | A smile that feels aged or is hidden from view |
One of the most serious long-term effects is loss of bite height. As teeth wear down, the upper and lower jaws come closer together and the lower third of the face can appear compressed. In such cases, patients may need bite reconstruction treatment in Klaipėda to restore function and natural facial proportions.
How is bruxism treated?
At Miško Clinic, we first look for the cause, then we deal with the consequences. The dentist assesses the teeth, bite and jaw joints, but also listens carefully: do you feel under constant pressure, has there been a recent stressful period, has your sleep changed, are you waking unrefreshed? Often, the first important step is simply naming what the body has been carrying silently.
Treatment is always planned around the individual. Some patients need only a custom night guard. Others need a broader approach, from muscle relaxation and habit awareness to restoring worn teeth and correcting the bite.
| Treatment option | Who it suits | What it helps with |
|---|---|---|
| Custom night guard or splint | Most patients who grind their teeth at night | Protects teeth and reduces muscle overload |
| Bite adjustment | Patients with uneven tooth contacts | Reduces pressure and restores balance |
| Bite reconstruction and restorations | Patients with severe tooth wear | Restores tooth height, function and aesthetics |
| Orthodontic treatment | When the bite is significantly misaligned | Addresses the underlying bite problem |
| Botulinum toxin injections | Marked overactivity of the chewing muscles | Temporarily reduces muscle force for around 3 to 4 months |
| Stress management or psychological support | When stress or anxiety is a clear driver | Targets the trigger behind the bruxism |
| Sleep hygiene and lifestyle changes | Almost all patients as a supporting measure | Improves sleep quality and may reduce grinding episodes |
Because stress is such a common driver, it deserves real attention. A night guard protects the teeth very well, but it protects against the effect rather than removing the cause. The best results usually come when we protect the teeth and reduce the load on the nervous system at the same time.
“A night guard is a good umbrella, but it does not stop the rain. If the rain is stress, we also need to build a stronger house: better sleep rhythms, calmer breathing, and permission to rest.” - Dr Lauras Smilgevičius.
Can teeth grinding go away by itself?
It is worth remembering that bruxism is not only a dental sign, but a whole-body signal that something is out of balance. The solution is rarely one single thing. Treatment usually happens in stages: assessment, stabilising the teeth, making a night guard or arranging restorative dental treatment, and sometimes wider dental prosthetic treatment if tooth wear is advanced.
In children, bruxism is often temporary and may settle as the baby teeth are replaced. In adults, persistent or worsening symptoms should be taken seriously. Early treatment helps prevent permanent damage and keeps the teeth and jaw joints stable.
What can you do at home every day?
A large part of bruxism management happens not in the dental chair, but in daily life. A few simple habits can make mornings noticeably calmer.
notice awake clenching: when you feel your teeth pressed together, gently relax your jaw and rest the tip of your tongue behind the upper front teeth
avoid coffee, energy drinks, alcohol and heavy meals close to bedtime
spend the last 10 minutes before sleep on slow breathing or gentle stretching
apply a warm compress to the cheeks before bed to relax the chewing muscles
attend regular professional oral hygiene appointments, so early signs of tooth wear can be spotted in time
When should you see a dentist about bruxism?
Morning jaw or neck pain can be the first quiet sign. If you often wake with tight muscles, pressure in the temples, or a headache that feels like a band around the head, you may be grinding or clenching during sleep.
It is also important to look at the teeth themselves. If the biting surfaces look unusually flat, chipped or shiny, this suggests excessive force. These changes can weaken teeth and eventually lead to fractures or more complex treatment.
Increased sensitivity is another symptom worth acting on. If cold water, hot drinks or sweet foods cause sharp discomfort, the protective enamel layer may already be damaged.
Many patients only learn about night-time grinding because a partner hears it. If someone has noticed grinding sounds while you sleep, mention it to your dentist. Even mild or occasional symptoms are worth checking, because early signs are much easier to manage than advanced tooth wear.

We do not aim simply to cover the symptoms with a standard guard. We want to understand what lies behind the grinding: stress, bite imbalance, muscle tension, poor sleep, or deeper emotional strain. Every case is assessed individually and we look for a lasting solution, not a quick patch. Sometimes that means careful restoration of teeth and bite. Sometimes it begins with a conversation about rhythm, rest and emotional wellbeing. Only by seeing the whole picture can we help properly.
If your smile is quietly asking for help, and morning jaw pain is telling you it is time to act, we invite you to come in for a calm conversation. No rush, no pressure, just clear guidance in the peace of Miško Clinic.
Frequently asked questions about bruxism
Is bruxism inherited?
Yes, a family tendency does exist. Studies suggest that 20 to 50 per cent of patients with bruxism have at least one close relative who also grinds their teeth. Inheritance does not make the problem inevitable, though. Symptoms usually appear when genetic tendency meets stress, poor sleep or another trigger.
Does a night guard cure bruxism?
A night guard protects rather than cures. It stops the teeth from rubbing directly against each other, reduces muscle overload and helps protect the jaw joint. It is a protective layer, while the deeper treatment happens when we also address stress, sleep, habits or bite problems.
Do children need treatment for bruxism?
Childhood bruxism often settles on its own because it is linked with growth and tooth changes. A dental check is sensible if the grinding is loud and frequent, the child has pain, or the teeth are visibly wearing down. We then choose a gentle monitoring or protection strategy for that child.
Can bruxism be completely cured?
If the cause is temporary, such as a short stressful period, symptoms may disappear completely. When the cause is an ongoing bite issue or chronic stress, we usually talk about control rather than a one-off cure: the teeth are protected, muscles are calmer, sleep improves and further wear is stopped. For most people, that is exactly the outcome they need.
How much does bruxism treatment cost?
The cost depends on the treatment path. The most accessible option is a custom night guard. In more advanced cases, such as bite reconstruction, tooth restoration or orthodontics, the plan is built in stages. At Miško Clinic, we always explain the situation, costs and alternatives clearly before treatment begins.
Can botulinum toxin help with bruxism?
Yes. When the chewing muscles are very overactive, botulinum toxin injections can temporarily reduce their force and ease symptoms. The effect usually lasts around 3 to 4 months. It is not usually the first option, but in more severe cases it can be combined with a night guard or bite restoration.
Can bruxism cause headaches?
Yes, quite often. The chewing and temple muscles are closely linked with common headache areas. If you wake with pressure in the temples or a tight, helmet-like headache, it is worth checking whether bruxism is contributing.
How soon will I feel the benefit of treatment?
Many patients using a custom night guard notice calmer mornings within 1 to 2 weeks: less muscle tension, fewer headaches and better sleep. The long-term benefit is even more important: protected teeth, a more stable jaw joint and prevention of further wear.
If you recognise even a few of these signs, do not wait. Let us arrange a calm discussion and a detailed bite assessment at Miško Dental Clinic in Klaipėda.
