Chronic cheek and lip trauma is a widespread habit that a significant portion of the population exhibits without realizing it. It often happens when anxious, during distraction, or even as a subconscious gesture during focused tasks.

Although occasional biting may look inconsequential, chronic cheek or lip biting is associated with the progression or exacerbation of jaw misalignment, which describes the misfit of teeth and jaws.

With prolonged repetition, ongoing force from the oral soft tissues against the teeth may alter tooth alignment. This is particularly significant in growing individuals whose skeletal structures remain malleable and are more responsive to environmental stimuli.

Persistent labial force can push front teeth backward, leading to overlapping teeth or an deep bite. Similarly, repeated cheek trauma can trigger localized edema, which can disrupt the natural positioning of back teeth.

Occasionally, persistent oral self-injury can result in the development of fibrous tissue that further restricts mandibular function. This can interfere with proper bite development and heightens the probability of requiring braces in adulthood.

In turn, 墨田区 前歯矯正 people with malocclusion may be at higher risk for repeated self-biting because misaligned teeth create abnormal ridges that easily catch the soft tissues while eating or speaking.

This creates a cycle: misaligned teeth cause trauma, and biting worsens malocclusion.

Breaking the habit requires conscious recognition and often habit-reversal training or the use of dental appliances to minimize friction between oral mucosa and dentition.

Clinicians routinely assess for evidence of oral trauma in routine exams because it can be an critical indicator in understanding the underlying causes of a patient’s occlusal dysfunction.

Addressing this habit early, during growth phases, can reduce the risk of more serious orthodontic issues and reduce the need for prolonged orthodontics in the future.
