Definition of Bruxism

What is bruxism?

Bruxism is a common condition characterized by the involuntary grinding, clenching, or gnashing of teeth. It often occurs during sleep but can also happen during wakefulness. It affects individuals of all ages, with studies suggesting that around 8-31% of the population experiences bruxism at some point in their lives. Although bruxism may seem harmless, it can lead to several oral health issues if left untreated.

Prevalence of Bruxism

Bruxism is more prevalent than you might think. Research suggests that it affects a significant portion of the population, with some studies estimating that as many as 1 in 3 people may experience bruxism at some point. It affects individuals of all ages, from children to adults. However, it is more commonly seen in children and tends to decrease as they get older. The exact prevalence rates may vary across different studies, but the overall message is clear: bruxism is a widespread condition that should not be ignored.

Potential causes of Bruxism

The exact cause of bruxism is not fully understood, but it is believed to be a multifactorial condition. Various factors can contribute to the development of bruxism. Some potential causes include stress, anxiety, abnormal bite, misalignment of teeth, certain medications, lifestyle factors, and sleep disorders such as sleep apnea. It is important to note that bruxism can be either primary, with no identifiable cause, or secondary, resulting from an underlying condition or medication. Identifying the potential causes can be crucial in determining the most appropriate treatment approach for managing bruxism.

Types of Bruxism

Sleep bruxism

Sleep bruxism refers to the grinding, clenching, or gnashing of teeth that occurs while you are asleep. It is often considered an unconscious behavior and is usually discovered by a sleeping partner who hears the noise or by a dentist who examines the signs of wear and tear on your teeth. Sleep bruxism can be disruptive to your sleep quality and can also lead to numerous oral health issues if left untreated.

Awake bruxism

Unlike sleep bruxism, awake bruxism occurs during the waking hours. It may involve clenching or grinding of teeth and can be a result of various factors such as stress, anxiety, or even concentration. Individuals with awake bruxism may not be aware of their habit, as it can be an automatic response to certain triggers or situations. It is important to note that individuals who have sleep bruxism may also experience awake bruxism, and vice versa.

Symptoms of Bruxism

Teeth grinding

One of the most common symptoms of bruxism is teeth grinding. This grinding sound can often be heard by sleeping partners or observed during a clinical examination. The grinding can be noisy and forceful, leading to wear and tear on the surfaces of your teeth. Over time, this can lead to significant damage to your tooth enamel and even result in tooth fractures or cracks.

Jaw pain and stiffness

Bruxism can cause jaw pain and stiffness due to the repeated clenching and grinding motion. This can lead to discomfort or pain, particularly in the temporomandibular joint (TMJ), which connects the jawbone to the skull. Individuals with bruxism may experience difficulty in opening or closing their mouths fully, and may also hear clicking or popping sounds when moving their jaws.


Headaches are another common symptom associated with bruxism. The constant tension and strain on the jaw muscles due to clenching and grinding can radiate pain to other areas of the head, leading to headaches. These headaches can vary in intensity and may be experienced as a dull ache or a more severe, throbbing pain. If you frequently wake up with headaches or if you notice a pattern between your headaches and teeth grinding, it is essential to consult a healthcare professional for further evaluation.

Tooth sensitivity

Tooth sensitivity is a common complaint among individuals with bruxism. The constant grinding and clenching can wear down the protective enamel layer of your teeth, exposing the more sensitive dentin underneath. As a result, you may experience heightened sensitivity to hot or cold foods and beverages. This sensitivity can range from mild discomfort to sharp, shooting pain. If you notice increased tooth sensitivity, it is important to seek dental advice to prevent further damage to your teeth.

Diagnosis of Bruxism

Clinical examination

To diagnose bruxism, your dentist will conduct a thorough clinical examination of your teeth, jaws, and oral tissues. They will check for signs of teeth grinding, tooth wear, and any other oral health issues that may be indicative of bruxism. Your dentist may also ask you questions about your symptoms, sleep patterns, and dental history to gather more information about your condition.

Dental history and X-rays

Obtaining a comprehensive dental history is crucial in diagnosing and understanding bruxism. Your dentist may ask you questions about your dental habits, such as whether you clench or grind your teeth, if you have any dental restorations, or if you have experienced any previous dental issues. X-rays may also be taken to assess the extent of tooth damage and to rule out any underlying dental conditions.

Sleep study

In some cases, a sleep study may be recommended to evaluate bruxism, especially if it primarily occurs during sleep. This involves staying overnight at a sleep center, where specialized equipment will monitor your sleep patterns, muscle activity, and teeth grinding. The data collected during the sleep study will help in confirming the presence of bruxism and determining the severity of the condition.

Effects of Bruxism on Teeth

Enamel wear and erosion

One of the significant effects of bruxism on teeth is enamel wear and erosion. The constant friction from grinding and clenching can gradually wear down the protective enamel layer of your teeth. Enamel is the outermost layer that shields your teeth from decay and sensitivity. As the enamel erodes, your teeth become more vulnerable to various oral health issues, including cavities, tooth sensitivity, and discoloration.

Tooth damage and fractures

Bruxism can lead to tooth damage and fractures due to the excessive forces applied during grinding and clenching. Over time, the constant pressure can weaken the structure of your teeth, making them more prone to breakage. Fractured teeth not only cause discomfort and pain but also require dental treatment, such as fillings, crowns, or in severe cases, extractions.

Tooth sensitivity

As mentioned earlier, bruxism can cause tooth sensitivity by wearing down the protective enamel layer. This exposes the more sensitive dentin, which contains microscopic tubules that connect to the nerves of your teeth. When these tubules are exposed, stimuli such as hot or cold foods and beverages can trigger a painful response. Managing bruxism and restoring the integrity of the enamel can help alleviate tooth sensitivity.

Temporomandibular joint (TMJ) disorders

Bruxism can also contribute to the development of temporomandibular joint (TMJ) disorders. The excessive strain and pressure on the TMJ due to clenching and grinding can lead to dysfunction and inflammation. This can result in symptoms such as jaw pain, clicking or popping sounds, difficulty opening or closing the mouth, and even lockjaw. Seeking timely treatment for bruxism can help prevent or alleviate TMJ disorders.

The Relationship Between Bruxism and Stress

Stress as a common trigger for bruxism

Stress is often considered one of the most common triggers for bruxism. When you are stressed, anxious, or tense, your body’s natural response may be to clench or grind your teeth unconsciously. This grinding and clenching of teeth may provide a temporary relief for the stress, but it can have detrimental effects on your oral health in the long run. Therefore, it is important to recognize and address stress as a contributing factor to bruxism.

Neurological and physiological mechanisms

Bruxism has been linked to various neurological and physiological mechanisms. The exact mechanisms behind why stress triggers bruxism are not yet fully understood. However, research suggests that stress can activate certain brain regions that control muscle activity, leading to increased muscle tension and subsequently bruxism. Additionally, stress can also disrupt sleep patterns, which may contribute to the occurrence of sleep bruxism.

Coping strategies to reduce bruxism

To effectively manage bruxism related to stress, it is important to adopt coping strategies that help reduce stress levels. Engaging in relaxation techniques such as deep breathing exercises, yoga, or mindfulness meditation can help relieve stress and promote a sense of calm. It can also be beneficial to identify and address any underlying stressors in your life, such as work-related pressures or personal conflicts. In some cases, seeking professional help from a therapist or counselor can provide additional support in managing stress and reducing bruxism.
