cheek biting

Cheek biting, a seemingly innocuous habit, often goes unnoticed until it becomes a persistent behavior with potentially serious consequences. It’s a habit that affects people of all ages, though it’s more prevalent in children and adolescents. Despite its commonality, the understanding of cheek biting remains limited, with many individuals unaware of the underlying causes, its impact on oral health, and strategies for managing this habit. In this comprehensive exploration, we delve into the intricacies of cheek biting, shedding light on its psychological and physiological aspects, its implications for oral health, and practical approaches for addressing this habit.


Understanding Cheek Biting

Cheek biting, medically known as morsicatio buccarum, refers to the habit of repetitively biting the inner lining of the cheeks. While occasional cheek biting might not raise concern, frequent and forceful biting can lead to tissue damage, discomfort, and even infections. The habit often manifests unconsciously, triggered by various factors such as stress, anxiety, boredom, or irregularities in dental occlusion.


Causes and Triggers

Several factors contribute to the development and perpetuation of cheek biting:

  • Stress and Anxiety
  • Oral Habits
  • Dental Occlusion
  • Boredom and Inattention


Stress and Anxiety

High levels of stress and anxiety are often cited as primary triggers for cheek biting. Individuals may resort to biting their cheeks as a coping mechanism, providing temporary relief from emotional tension.

Oral Habits

Cheek biting can be a learned behavior, especially if individuals observe it in their family members or peers. Nail-biting, lip-biting, and other oral habits may coexist with cheek biting, forming a cluster of repetitive behaviors.

Dental Occlusion

Irregularities in dental alignment or malocclusion, where the teeth do not fit together properly, can contribute to cheek biting. Uneven teeth may inadvertently come into contact with the cheeks, increasing the likelihood of biting.

Boredom and Inattention

In some cases, individuals engage in cheek biting out of boredom or absentmindedness. It becomes a habitual response to moments of idleness or lack of stimulation.


Consequences of Cheek Biting

While cheek biting may seem trivial, its consequences can be significant, affecting both oral health and overall well-being:

  • Tissue Damage
  • Pain and Discomfort
  • Oral Health Complications
  • Psychological Impact


Tissue Damage

Persistent cheek biting can lead to tissue trauma, including ulcers, lesions, and inflammation. Continuous irritation of the oral mucosa may hinder the healing process, exacerbating discomfort and increasing the risk of infection.

Pain and Discomfort

Chronic cheek biting often causes persistent pain and discomfort, making it difficult to eat, speak, or perform daily activities comfortably. The constant presence of oral lesions can also impair quality of life and affect psychological well-being.

Oral Health Complications

Prolonged cheek biting can damage the delicate tissues of the cheeks, creating open wounds susceptible to bacterial infection. Poor oral hygiene practices may further exacerbate the risk of infection, leading to complications such as abscesses or cellulitis.

Psychological Impact

Cheek biting is not merely a physical habit; it can also have psychological implications. Individuals may experience feelings of guilt, embarrassment, or frustration due to their inability to control the habit. In severe cases, it may contribute to low self-esteem or exacerbate preexisting mental health conditions.


Managing Cheek Biting

Addressing cheek biting requires a multifaceted approach that targets both the underlying triggers and the habit itself. Here are some practical strategies for managing cheek biting:

  • Identify Triggers
  • Stress Management Techniques
  • Cognitive-Behavioral Therapy (CBT)
  • Oral Hygiene Practices
  • Orthodontic Treatment
  • Behavioral Modification Techniques
  • Dental Appliances


Identify Triggers

Begin by identifying the triggers that prompt cheek biting episodes. Keeping a journal can help individuals recognize patterns and understand the circumstances surrounding their biting behavior.

Stress Management Techniques

Since stress and anxiety often exacerbate cheek biting, adopting stress management techniques such as mindfulness, deep breathing exercises, or progressive muscle relaxation can help individuals cope with emotional triggers more effectively.

Cognitive-Behavioral Therapy (CBT)

CBT can be beneficial for individuals struggling to control their cheek biting habits. This therapy focuses on identifying and modifying negative thought patterns and behaviors, helping individuals develop healthier coping mechanisms.

Oral Hygiene Practices

Maintaining good oral hygiene can help prevent complications associated with cheek biting. Rinsing the mouth with saltwater or antiseptic mouthwash can promote healing and reduce the risk of infection in oral lesions.

Orthodontic Treatment

In cases where malocclusion contributes to cheek biting, orthodontic intervention may be necessary to correct dental alignment and alleviate biting-related issues.

Behavioral Modification Techniques

Employing behavioral modification techniques such as habit-reversal training or stimulus control can help individuals become more aware of their biting behavior and substitute it with alternative actions.

Dental Appliances

Dentists may recommend the use of dental appliances such as mouthguards or orthodontic devices to prevent cheek biting and protect the oral tissues from injury.



Cheek biting, though often dismissed as a harmless habit, can have significant implications for oral health and overall well-being. Understanding the underlying causes, triggers, and consequences of cheek biting is essential for developing effective management strategies. By addressing the habit from both psychological and physiological perspectives and implementing targeted interventions, individuals can gain control over their biting behavior and alleviate associated discomfort and complications. With awareness, patience, and appropriate support, overcoming cheek biting is achievable, paving the way for improved oral health and enhanced quality of life.
