Silent Struggles: Understanding the Phenomenon of Biting Your Tongue in Sleep


Sleep is often associated with tranquility and relaxation, a time when the body and mind rejuvenate. However, for some individuals, the night brings about unexpected challenges. One such nocturnal quirk is biting the tongue during sleep, a phenomenon that can leave people puzzled and even a little sore come morning. In this article, we’ll delve into the intriguing world of biting the tongue in sleep, exploring its potential causes, implications, and ways to address this silent struggle.

The Mystery Behind Biting the Tongue:

Imagine waking up to the sensation of a sore tongue, wondering how such a seemingly involuntary action could occur. Biting the tongue during sleep can be disconcerting, but understanding its roots can offer clarity. The reasons behind this phenomenon can vary, often intersecting with factors like sleep disorders, sleep positions, and even dental issues.

Sleep Disorders and Tongue Biting:

Sleep disorders like sleep bruxism (teeth grinding) and sleep-related rhythmic movement disorder can play a significant role in biting the tongue during sleep. These disorders involve involuntary movements, including jaw clenching and teeth grinding, which can lead to tongue being caught in between, resulting in accidental biting.

Sleep Positions and Their Impact:

The position you sleep in can inadvertently contribute to tongue biting. Individuals who sleep on their stomachs or sides may be more prone to this phenomenon due to the way their jaw and tongue interact during sleep. Tongue biting can also occur when a person changes positions during the night, catching the tongue between the teeth.

The Dental Connection:

Dental issues, such as misaligned teeth or an improper bite (malocclusion), can amplify the likelihood of biting the tongue during sleep. When the teeth do not align properly, the tongue might find itself in an uncomfortable position that increases the risk of being bitten.

Implications and Discomfort:

While biting the tongue in sleep might seem harmless, it can lead to discomfort and even pain. In some cases, tongue injuries resulting from repeated biting can cause soreness, swelling, and minor bleeding. The discomfort can extend beyond the physical, with individuals feeling anxious about the potential recurrence of this nighttime occurrence.

Addressing the Issue:

Understanding the underlying causes of biting the tongue during sleep is the first step toward finding solutions. Here are some strategies to consider:

  1. Consult a Professional: If you suspect that a sleep disorder or dental issue is contributing to tongue biting, it’s wise to consult a healthcare professional. A dentist or sleep specialist can assess your situation and recommend appropriate interventions.
  2. Sleep Position: Adjusting your sleep position can make a significant difference. Sleeping on your back can reduce the chances of accidentally biting your tongue.
  3. Mouthguards: Dental professionals can provide custom-made mouthguards that help protect the teeth and tongue from the effects of grinding and clenching.
  4. Stress Management: Stress can exacerbate teeth grinding and related movements. Practicing relaxation techniques and managing stress can indirectly help reduce the occurrence of tongue biting during sleep.


Biting the tongue during sleep might be an unusual and puzzling occurrence, but it is not an isolated phenomenon. Understanding the potential causes and seeking appropriate guidance can alleviate discomfort and prevent recurrent incidents. By unraveling the mysteries behind this silent struggle, individuals can look forward to nights of restful sleep, free from the discomfort of unintentional tongue biting.
