Teeth grinding often seems like a minor issue until consequences appear: increased enamel sensitivity, tension in the jaw, headache after sleep, discomfort while chewing, or a feeling of “tired” facial muscles. In this article, we will explain why people may grind their teeth, which symptoms should not be ignored, why prolonged jaw clenching is dangerous, and how to act correctly to protect the teeth, reduce discomfort, and prevent complications.
What is bruxism
Bruxism is involuntary jaw clenching or rubbing the teeth against each other, which may occur during sleep or during the day. In most cases, a person does not notice this on their own, especially if jaw tension occurs at night.
It is important to understand that bruxism is not simply a “habit of grinding the teeth.” During such episodes, the teeth and chewing muscles are exposed to a load that can be much stronger than during normal chewing. If this happens regularly, tooth sensitivity, enamel wear, jaw pain, facial muscle tension, or discomfort in the temporomandibular joint may develop over time.
Doctors at Oxford Medical recommend paying attention to teeth grinding during sleep, a morning feeling of tiredness in the jaw, frequent headaches, and increased enamel sensitivity. Such signs may indicate that the dentofacial system is regularly overloaded, so it is advisable to undergo an examination and diagnostics.
Why people grind their teeth
The causes of bruxism are not always obvious. In some patients, the problem is associated with nervous tension; in others, with sleep disorders, bite characteristics, overload of the chewing muscles, or a combination of several factors. That is why it is important not to look for one universal cause, but to assess a person’s general condition, lifestyle, sleep, dental health, and accompanying symptoms.
Main causes of bruxism
Most often, the causes of bruxism are associated with a combination of several factors that affect the work of the chewing muscles and the nervous system. These include:
- stress, anxiety, emotional overstrain;
- chronic fatigue and lack of sleep;
- the habit of clenching the jaws during concentration or nervous tension;
- bite disorders and uneven jaw closure;
- missing individual teeth;
- incorrectly fitted fillings, crowns, or orthopedic dental structures;
- snoring, difficulty breathing through the nose, frequent awakenings at night;
- excessive consumption of caffeine, smoking, alcohol;
- prolonged overstrain of the neck and facial muscles.
According to National Institutes of Health, bruxism often has a multifactorial nature and may be associated with psycho-emotional tension, sleep disorders, and neurological factors. That is why in some cases a patient may need not only a consultation with a dentist, but also consultations with other specialists.
Teeth grinding at night
Nocturnal bruxism occurs during sleep, so a person usually does not notice that they strongly clench their jaws or grind their teeth. Often, close people are the first to notice the problem because they hear the characteristic sound, or a dentist notices enamel changes during an examination. The patient usually pays attention to indirect symptoms: tension in the jaw after waking up, pain in the temples, headache, or tooth sensitivity.
Teeth grinding at night often intensifies during periods of stress, overfatigue, or lack of sleep. In some people, it is combined with restless sleep, snoring, or frequent awakenings. Since a person does not control the force of jaw clenching during sleep, the chewing muscles may regularly experience excessive load.
Teeth grinding during the day
Daytime bruxism usually manifests not as pronounced grinding, but as a habit of strongly clenching the teeth. This often happens during work, study, driving a car, or moments of anxiety and concentration. Many people do not even notice it until a feeling of fatigue in the jaw or tension in the chewing muscles appears.
Teeth grinding during the day is most often associated with emotional tension and stress. Normally, the teeth should not constantly touch each other at rest. If a person gets used to keeping the jaws clenched throughout the day, the load on them gradually increases.
Doctors at Oxford Medical recommend paying attention from time to time to the position of the jaw, especially while working at a computer or in tense situations. This simple habit helps notice the problem earlier and reduce overstrain of the chewing muscles.
A child grinds their teeth: possible causes

Bruxism in children is quite common and does not always indicate a serious problem. In childhood, the nervous system and chewing muscles are more sensitive to overfatigue, emotional stress, and sleep schedule disturbances, so episodes of grinding may appear even in healthy children.
Possible causes of bruxism in childhood may include:
- emotional tension, anxiety, or stress;
- overfatigue and excessive workload during the day;
- lack of sleep or disruption of the rest routine;
- difficulty breathing through the nose;
- snoring or restless sleep;
- change from primary dentition to permanent dentition;
- bite disorders;
- the habit of strongly clenching the jaws.
In many children, manifestations of bruxism decrease with age. However, if a child regularly clenches their teeth, sleeps poorly, complains of fatigue in the jaw, or has noticeable enamel wear, it is worth consulting a doctor for an examination and determination of the cause.
Why a child grinds their teeth at night
Nocturnal bruxism in children is most often associated with overfatigue, emotional overstrain, or sleep characteristics. Some children begin to clench their jaws more strongly after a busy day, active emotions, anxiety, or a change in their usual routine. Bruxism may also intensify during adaptation to kindergarten, school, or after stressful situations.
Doctors at Oxford Medical explain: parents are often concerned about why a child grinds their teeth when sleeping. It is important to understand that this problem does not always indicate a serious disease. In many children, episodes of nocturnal bruxism become less frequent over time or disappear completely.
At the same time, it is worth paying attention to accompanying symptoms: snoring, mouth breathing, restless sleep, frequent awakenings, or complaints of tiredness after sleep. In such cases, the child may need an additional examination to assess the causes of sleep disturbance and the condition of the dentofacial system.
Why a child grinds their teeth during the day
Daytime bruxism in children more often manifests as a habit of strongly clenching the teeth in moments of anxiety, concentration, or emotional tension. A child may do this while studying, doing homework, playing, or using gadgets, even without noticing it.
Sometimes children clench their jaws during stress, resentment, anxiety, or overfatigue. At a younger age, this may also be a reaction to an excess of emotions or difficulty controlling tension.
In such cases, it is important to pay attention to the sleep schedule, level of workload, emotional state of the child, and the opportunity to rest during the day. If the habit persists for a long time or complaints of jaw pain or headache appear, it is worth consulting a specialist.
Why bruxism is dangerous
If bruxism occurs regularly, constant overstrain of the jaws may gradually affect not only the condition of the teeth, but also the work of the chewing muscles and joints. Complications usually develop gradually, so a person does not always immediately associate them specifically with the habit of clenching the teeth.
Possible consequences:
- enamel wear and increased sensitivity;
- appearance of cracks, chips, or damage to fillings;
- pain and tension in the chewing muscles;
- discomfort or clicking in the jaw joint;
- headache, especially after sleep;
- pain in the temples or face;
- sleep disturbance and a feeling of tiredness in the morning;
- overload of the dentofacial system.
According to National Institutes of Health, long-term bruxism can lead to tooth damage, overload of the chewing muscles, and the development of temporomandibular joint dysfunction. That is why it is important not to ignore regular teeth grinding and to consult a doctor in time, especially if discomfort, enamel sensitivity, or morning jaw tension appears.
How to treat bruxism

Treatment of bruxism depends on the causes, frequency of episodes, and how strongly the teeth and chewing muscles are overloaded. The main goal of therapy is to reduce jaw tension, protect the teeth from wear, and eliminate the factors that support bruxism.
Before starting treatment, the doctor assesses the condition of the bite, chewing muscles, and jaw joint. If necessary, additional examinations may be prescribed, in particular an orthopantomogram, as well as consultations with related specialists.
How to get rid of bruxism in adults
Treatment of bruxism in adults is selected individually. Most often, a comprehensive approach is used, which helps reduce the load on the teeth and chewing muscles.
The doctor may recommend:
- mouthguards for bruxism to protect the teeth during sleep;
- correction of bite disorders;
- normalization of the sleep schedule;
- reduction of stress levels and emotional overstrain;
- reduction of the load on the chewing muscles;
- treatment of accompanying sleep disorders.
In cases of pronounced overstrain of the chewing muscles, botox is sometimes used, which helps temporarily reduce the force of jaw clenching. If bruxism is accompanied by sleep disorders, headaches, or other neurological symptoms, a consultation with a neurologist may be needed.
If bruxism is associated with a bite disorder or overload of the jaw joint, the patient may be recommended a consultation with a gnathologist. In some cases, an additional examination is needed to clarify the causes of the symptoms.
Doctors at Oxford Medical recommend not self-medicating, because the effectiveness of therapy depends primarily on the correctly identified cause of bruxism.
How to treat bruxism in children
Treatment of bruxism in children depends on age, frequency of episodes, and the causes that may provoke teeth grinding. If the manifestations occur rarely, do not disturb sleep, and do not lead to tooth wear, the doctor may recommend observation and monitoring of the condition over time.
In most cases, it is important to start with simple steps:
- establish a stable sleep schedule;
- reduce emotional overload before bedtime;
- limit active games and gadgets in the evening;
- monitor whether the child breathes freely through the nose;
- pay attention to snoring, restless sleep, or frequent awakenings;
- check the condition of the teeth, bite, and presence of enamel wear.
If a child regularly grinds their teeth, complains of jaw pain or headache, or has noticeable tooth wear, a consultation with a dentist is needed. If necessary, the doctor may advise examination by other specialists, for example a neurologist.
Bruxism is a common problem that can occur in both adults and children. Regular jaw clenching gradually overloads the dentofacial system and may lead to enamel wear, pain in the chewing muscles, and discomfort in the jaw joint.
It is important not to ignore symptoms, even if they occur only periodically. Timely diagnostics helps determine the cause of bruxism, reduce the load on the teeth, and select treatment that will help prevent complications in the future.
