The Psychological Factors Behind Bruxism

Psychological aspects of Bruxism

Bruxism refers to the involuntary clenching of teeth and is a condition that can affect individuals of any age. Even though this condition can be a result of bite misalignment or sleep disorders, research has shown that psychological factors play a significant role in the development and exacerbation of bruxism.

In this article, we will explore the psychological factors behind bruxism and pay close attention to the intricate mind-teeth connection that not many people are aware of. By understanding these underlying psychological influences, individuals and healthcare professionals can gain valuable insights into the management and treatment of bruxism.

Understanding Bruxism

Bruxism is a multifactorial condition that involves the gnashing, clenching, and grinding of teeth. Individuals can experience it during sleep or while awake, and it can lead to numerous complications, such as toothache, jaw pain, headaches, and disrupted sleep patterns.

The Psychological Factors Behind Bruxism 

Psychological factors of Bruxism

1. Stress and Anxiety

Stress and anxiety are key psychological factors closely associated with bruxism. Individuals experiencing high levels of stress or anxiety, whether related to work, relationships, or other life circumstances, are more prone to clenching or grinding their teeth.

Bruxism often serves as an unconscious coping mechanism to release tension and express underlying emotional distress. Moreover, studies have shown a bidirectional relationship, where bruxism can also increase stress levels and perpetuate a cycle of stress-related grinding.

2. Personality Traits

Certain personality traits have been linked to an increased risk of bruxism. Individuals with Type A personalities, characterized by competitiveness, time urgency, and a strong drive for achievement, may be more susceptible to bruxism due to their inherent high levels of stress and perfectionism.

Similarly, individuals with high levels of aggression or hostility may exhibit more pronounced bruxism behaviors.

3. Emotions and Psychological Disorders

Emotional states and psychological disorders play a significant role in the development and exacerbation of bruxism. Depression, anxiety disorders, post-traumatic stress disorder (PTSD), and eating disorders have been associated with a higher prevalence of bruxism.

Negative emotions, such as anger, frustration, or sadness, can manifest as teeth grinding during sleep or wakefulness.

4. Maladaptive Coping Mechanisms

Bruxism can be viewed as a maladaptive coping mechanism for dealing with emotional and psychological stressors. Individuals who struggle with managing stress may unknowingly resort to teeth grinding as a means of emotional release or as a way to regain a sense of control.

It becomes a habitual response to emotional tension, leading to the reinforcement and perpetuation of bruxism.

5. Sleep Disorders and Sleep-Related Bruxism

Sleep disorders, such as sleep apnea and insomnia, have been linked to the development of sleep-related bruxism. Sleep apnea, characterized by repeated pauses in breathing during sleep, can cause airway obstruction, leading to increased muscle activity, including teeth grinding.

Insomnia, on the other hand, disrupts sleep quality and can heighten stress levels, contributing to awake bruxism. The bidirectional relationship between bruxism and sleep disorders highlights the need for comprehensive evaluation and management of both conditions.

6. Medications and Substances

Certain medications and substances have been associated with bruxism. Antidepressants, particularly selective serotonin reuptake inhibitors (SSRIs), have been linked to an increased risk of bruxism.

Stimulants like amphetamines or recreational drugs such as cocaine and ecstasy can also trigger teeth grinding. Moreover, excessive caffeine or alcohol consumption can contribute to bruxism by altering neurotransmitter levels and increasing muscle tension.

7. Childhood Trauma and Psychological Factors

Childhood trauma, such as physical, emotional, or sexual abuse, has been identified as a potential psychological factor behind bruxism.

Traumatic experiences can have long-lasting effects on an individual's psychological well-being, leading to chronic stress, anxiety, or depression, which may manifest as bruxism.

Furthermore, individuals who have experienced trauma may develop maladaptive coping mechanisms, including teeth grinding, as a way to cope with unresolved emotions and distress.

8. Perfectionism and Control

Perfectionism and control

Perfectionism and a need for control have been linked to bruxism. Individuals with perfectionistic tendencies may carry a constant sense of pressure and self-imposed high expectations. The inability to meet these standards can lead to increased stress levels and a higher likelihood of teeth grinding.

Furthermore, the act of grinding or clenching teeth may serve as a subconscious attempt to exert control in situations where individuals feel overwhelmed or helpless.

9. Awareness and Psychological Interventions

Increasing awareness of the psychological factors behind bruxism is essential for effective management and treatment.

Psychological interventions, such as cognitive-behavioral therapy (CBT), relaxation techniques, stress management strategies, and counseling, can help individuals identify and address underlying emotional and psychological triggers. These interventions aim to reduce stress, modify maladaptive coping mechanisms, and promote healthier behavioral responses.

Here are some ways to deal with the psychological factors behind bruxism:

1. Identify and Manage Stress

Since stress is a major contributor to bruxism, it is essential to identify and manage stressors effectively. Engage in stress-reducing activities such as regular exercise, mindfulness meditation, deep breathing exercises, and relaxation techniques like yoga or tai chi.

Additionally, explore stress management strategies such as time management, setting realistic expectations, and seeking support from loved ones or professional counselors.

2. Seek Emotional Support

If you are dealing with underlying emotional issues such as anxiety, depression, or trauma, it is essential to seek appropriate emotional support.

Reach out to a mental health professional who can provide guidance, support, and therapeutic interventions tailored to your specific needs.

3. Dental Interventions

While addressing psychological factors is crucial, it is also important to consult with a dental professional. They can provide interventions such as prescribing dentist-recommend night guards or a splint to protect teeth from grinding and reduce muscle tension.

These oral devices can help alleviate the physical consequences of bruxism while addressing the underlying psychological factors. You can easily find teeth grinding guards for sale here.


Bruxism is not solely a dental or physiological issue but is also influenced by various psychological factors. Stress, anxiety, personality traits, emotions, sleep disorders, trauma, and maladaptive coping mechanisms contribute to the development and perpetuation of bruxism.

Recognizing the psychological aspects of bruxism is crucial for developing comprehensive treatment approaches that address both the dental and psychological aspects of the condition. By addressing underlying psychological factors through interventions such as CBT, stress management, and relaxation techniques, individuals can better manage and alleviate bruxism, improving their overall oral health and well-being.
