Accidentally biting the side of one’s tongue is a common experience. This involuntary action, while typically brief, can range from a mild annoyance to a sharp, painful jolt. The underlying reasons for biting the tongue are not always immediately clear, leading many to seek understanding about this phenomenon.
Everyday Explanations for Tongue Biting
Many instances of tongue biting are simply accidental. Eating too quickly or talking while chewing can lead to a momentary misalignment, causing the tongue to get caught between the teeth. Distraction during meals or sudden movements can also contribute to these bites.
Fatigue can reduce coordination, making accidental tongue bites more likely as muscle control is compromised. Additionally, adjusting to new dental work, such as fillings, crowns, or braces, can temporarily alter the mouth’s landscape, increasing the chance of biting. These occurrences are generally isolated incidents, healing quickly without lasting issues.
Medical and Dental Factors to Consider
While often benign, persistent tongue biting can indicate underlying medical or dental conditions that warrant attention. Misaligned teeth (malocclusion) can cause the jaw to close improperly, increasing the likelihood of the tongue getting in the way. Issues with the temporomandibular joint (TMJ) can affect jaw movement and contribute to accidental biting.
Bruxism, the habit of teeth grinding or clenching, often occurs unconsciously, especially during sleep. This grinding motion can trap the tongue between the teeth, leading to repeated injury. Certain sleep-related disorders, such as sleep apnea or rhythmic movement disorder, can also cause involuntary mouth movements and tongue biting during the night.
Neurological conditions, including epilepsy and other disorders affecting muscle control, may lead to uncontrolled movements that result in tongue trauma. Stress or anxiety can manifest as unconscious habits like tongue chewing or clenching, and some medications can also induce repetitive mouth movements, increasing the risk of biting.
What Happens When Biting Persists
When tongue biting becomes a regular occurrence, it can lead to uncomfortable consequences for oral health. Repeated trauma can cause painful sores and ulcers on the tongue. These injuries can become inflamed, making eating and speaking difficult.
The presence of open wounds also increases the risk of bacterial infection, as the mouth naturally contains numerous microorganisms. In chronic cases, repeated injury and healing can lead to the formation of scar tissue, which may alter the tongue’s texture and appearance over time.
Steps to Take and When to See a Professional
To reduce accidental tongue biting, practice mindful eating: slow down, take smaller bites, and chew thoroughly without distractions. Managing stress through techniques like deep breathing, meditation, or yoga may also help, particularly if stress contributes to unconscious oral habits. For individuals who suspect bruxism, a nightguard can provide a protective barrier during sleep, preventing injury.
Seek professional help if tongue biting persists or is accompanied by concerning symptoms. A visit to a dentist or doctor is recommended for persistent pain, recurring sores that do not heal within a few weeks, or signs of infection (excessive redness, swelling, pus, or fever). Difficulty chewing, speaking, associated jaw pain, or if biting significantly impacts daily life also warrant a professional evaluation to identify underlying causes.
