Biting the inside of your cheek is a common experience. This seemingly minor irritation can range from an infrequent, accidental occurrence to a persistent, unconscious habit. Understanding the reasons behind this phenomenon can help explain why you might frequently bite your inner cheek. This article explores the factors contributing to cheek biting and offers guidance on how to address them.
Underlying Causes of Cheek Biting
Cheek biting can stem from several sources, ranging from simple accidents to complex behavioral patterns. Accidental biting frequently occurs during everyday activities like eating quickly, talking while chewing, or during sudden jaw movements. Dental issues, such as misaligned teeth or poorly fitted dental devices like braces or retainers, can also increase the likelihood of inadvertently catching the cheek. Erupting wisdom teeth might similarly contribute to these accidental bites.
Beyond accidental occurrences, many people develop habitual cheek biting, medically known as morsicatio buccarum. This condition is classified as a body-focused repetitive behavior (BFRB) and is often an unconscious response to stress, anxiety, boredom, or tension. Individuals might not even be aware they are doing it, especially when deeply engrossed in thought or activity. The repetitive nature of this habit can lead to a cycle where damaged tissue creates an urge to smooth the area, perpetuating the behavior.
Some individuals also experience cheek biting during sleep, often linked to bruxism, or teeth grinding. A mouth guard can provide a barrier to prevent contact between the teeth and the cheek during sleep.
Identifying Chronic Cheek Biting
Distinguishing between an occasional, accidental bite and a more persistent, chronic condition is important. Chronic cheek biting, or morsicatio buccarum, often leaves noticeable physical signs on the inner lining of the mouth, known as the buccal mucosa. These signs include white, shredded, or rough patches on the cheek, which may appear thickened or calloused.
The affected areas might feel tender, sore, or inflamed, and may bleed. Repeated trauma can lead to the formation of ulcers, sores, or scar tissue within the cheek. These physical changes can cause discomfort during eating or speaking, and individuals might unconsciously try to smooth out the damaged tissue, worsening the issue.
When to Consult a Professional
While occasional cheek biting is not a cause for concern, certain indicators suggest seeking professional evaluation. Consult a healthcare professional if biting leads to persistent pain, recurring sores, or non-healing ulcers inside your mouth. Signs of infection, such as increased redness, swelling, or pus, also warrant immediate attention.
Significant tissue damage or if the habit causes emotional distress, such as feelings of guilt or shame, indicates a need for professional help. A dentist can assess for dental issues like misaligned teeth or ill-fitting dental work. For habit-related concerns, a doctor or mental health professional can help identify triggers and develop strategies to manage the behavior.
Practical Tips to Stop Biting
Developing awareness of when and why you bite your cheek is a foundational step. Keeping a mental note or log of instances can help identify specific triggers, such as stress, boredom, or particular activities. Once triggers are recognized, efforts can be made to avoid them or redirect the urge.
For those whose cheek biting is linked to stress or anxiety, incorporating stress management techniques is beneficial. Practices such as deep breathing exercises, meditation, or calming activities can help alleviate tension. Finding alternative ways to cope with stress, such as squeezing a stress ball, can redirect the physical urge.
Behavioral modification strategies involve substituting the biting habit with a less harmful action. Chewing sugar-free gum can provide a similar oral sensation and occupy the mouth, preventing cheek biting. Sipping water or consuming healthy, crunchy snacks can also serve as a distraction.
If dental factors are suspected, consult a dentist. They can address sharp tooth edges, correct misalignments through orthodontic solutions, or adjust ill-fitting dental restorations. For individuals who bite their cheeks during sleep, a custom-fitted mouthguard creates a protective barrier, allowing the tissue to heal. Practicing mindful eating by slowing down and focusing on jaw movements can also reduce accidental bites.
