What You'll Learn

Potential causes: nightmares, crooked teeth, stress, and more
Biting your tongue during sleep can be caused by various factors, some of which may be indicative of underlying medical conditions. Here are some potential causes:
Nighttime Seizures and Rhythmic Movement Disorders:
Nighttime seizures are a common cause of tongue biting. Individuals with epilepsy or rhythmic movement disorder may experience uncontrolled body movements during a seizure or episode, leading to unintentional tongue biting. This is particularly common in children, who may rock their bodies, bang their heads, or produce humming sounds during sleep.
Stress and Anxiety:
Stress and anxiety are significant contributors to tongue biting during sleep. High-stress levels and anxiety can lead to bruxism, or teeth grinding and clenching, which often affects the teeth and jaws but can also result in biting the tongue and cheeks. Reducing stress through relaxation techniques, such as deep breathing, meditation, or yoga, can help lower the risk of tongue biting.
Facial Muscle Spasms:
Facial and jaw muscle spasms can cause the chin to tremble uncontrollably during sleep, leading to tongue biting. These spasms are most common in children but can occur at any age. Muscle spasms can be caused by various factors, including dehydration, overexertion, and stress.
Sleep Bruxism and Malocclusion:
Sleep bruxism, or teeth grinding, can be related to stress, anxiety, or genetic factors. It is more prevalent among smokers, regular alcohol drinkers, high caffeine consumers, and snorers. Malocclusion, or misaligned teeth, can also contribute to tongue biting during sleep. The incorrect jaw position due to misalignment increases the chances of the tongue slipping between the teeth, leading to accidental bites.
Other Factors:
In some cases, tongue biting during sleep may be caused by specific underlying conditions, such as Lyme disease, sleep apnea, epilepsy, or facio-mandibular myoclonus, a rare neurologic disorder. Additionally, crooked teeth or an overbite can contribute to this issue. Nightmares have also been anecdotally linked to tongue biting during sleep, although there is limited scientific evidence to support this claim.

Treatments: mouthguards, CBT, antiseizure medication, etc
Biting your tongue while sleeping can be a symptom of various conditions, including sleep bruxism, sleep apnea, and epilepsy. Treatment options for this condition include:
Mouthguards
One of the most common and effective treatments for tongue biting during sleep is the use of a mouthguard. Mouthguards can help prevent future injuries by softening the bite and providing a barrier between the teeth and tongue. Custom-fitted dental mouthguards or splints can be created by a dentist or sleep dentistry provider to ensure a perfect fit, but non-customized versions are also available.
CBT and Stress Management
Chronic tongue biting may be linked to underlying psychological factors such as stress, anxiety, and depression. Cognitive-behavioral therapy (CBT) or counseling can help address these issues and provide tailored strategies to manage stress and anxiety, reducing the risk of tongue biting. Relaxation techniques such as yoga and meditation can also help prevent sleep disorders and manage stress.
Antiseizure Medication
For those experiencing nocturnal seizures or epilepsy, antiseizure medication can help prevent tongue biting during sleep. A neurologist can conduct a sleep study to determine if seizures are occurring during sleep and recommend appropriate medication.
Addressing Dental Issues
Misalignment of teeth (malocclusion) can contribute to tongue biting. Orthodontic treatment or other dental interventions, such as braces or Invisalign, may be necessary to correct the underlying issue and prevent further tongue injuries.
Lifestyle Changes
Lifestyle changes can also help reduce the occurrence of tongue biting during sleep. Quitting smoking, discontinuing illicit drug use, and modifying eating habits can all contribute to a reduction in tongue biting. Additionally, maintaining good oral hygiene and addressing any oral health issues can also help prevent accidental tongue biting.

Symptoms: bleeding, soreness, swollen tongue, and more
Biting your tongue while sleeping can cause a lot of pain and some damage to the soft tissues of your tongue. The bite strength is strong enough to cause bleeding, soreness, and swelling. Other symptoms include ulcer development, infection, and a condition called "scalloping".
If you experience nocturnal tongue biting, you may wake up at unusual times in the night without any reason. You may also experience seizures, indicating undiagnosed or untreated epilepsy. Tongue biting can also be a symptom of rhythmic movement disorder, which is common in children.
If you experience tongue bleeding, it is recommended to visit a doctor to assess the severity and determine if further medical attention is required. Tongue injuries usually heal quickly and may not need medical intervention. However, if you notice symptoms such as ulcer development, redness, excessive bleeding, pus, or lacerations, seeking medical attention is advised.
To prevent further tongue biting, it is important to address any underlying medical conditions, such as sleep apnea, epilepsy, bruxism, or teeth grinding and clenching. Wearing a custom-made night guard or mouthguard while sleeping can help limit the damage to your tongue by reducing the force exerted on it.
If you suspect that your tongue biting is caused by illicit drug use, stopping the drug can help alleviate the symptoms. Additionally, if you experience seizures or muscle spasms in your face and jaw at night, consulting a doctor and taking antiseizure medication may be beneficial.

Prevention: saltwater, ice, avoiding spicy food, etc
Biting your tongue during sleep can be caused by underlying medical conditions such as sleep apnea, epilepsy, teeth grinding, or sleep bruxism. If you frequently bite your tongue during sleep, it is advisable to consult a doctor to determine the cause and receive appropriate treatment.
To prevent tongue biting while sleeping, addressing any underlying medical conditions is crucial. Consult your doctor or dentist about the use of a mouthguard, which can help prevent injuries caused by teeth grinding or sleep bruxism. Additionally, consider participating in a sleep study to identify any underlying sleep disorders that may be contributing to tongue biting.
In terms of prevention specifically related to the use of saltwater, ice, and avoiding spicy food, here are some detailed instructions:
Saltwater
Rinsing your mouth with saltwater can be an effective way to promote healing and prevent infections after biting your tongue. Mix 1 teaspoon (5 grams) of salt with 1 cup (250 milliliters) of warm tap water. Swish the saltwater mixture in your mouth for 15 to 20 seconds, then spit it out. Repeat this process up to 3 times a day, especially after meals, until your tongue is healed. The salt helps to kill bad bacteria in the mouth, creating a cleaner environment and reducing the chances of infection.
Ice
Applying ice to the injured area can help reduce swelling and provide temporary numbness to alleviate pain. Wrap an ice cube in a clean cloth or use ice cubes in a plastic bag, holding it against the affected area for a minute or until numbness sets in. Repeat this process several times over the next few days as needed. Alternatively, you can use a frozen fruit bar, especially when caring for an injured child.
Avoiding Spicy Food
While there is no direct mention of avoiding spicy food in the context of biting your tongue during sleep, it is generally advisable to avoid irritants that can aggravate the injured tissue and slow down the healing process. Spicy foods may cause further irritation or pain, so it is recommended to refrain from consuming them until the tongue has healed.
Remember, if you experience severe bleeding that doesn't stop after applying pressure for 15 minutes, seek medical help immediately as you may have bitten through your tongue.

When to see a doctor: frequent biting, severe pain, etc
Biting your tongue while sleeping can be caused by underlying medical conditions such as epilepsy, sleep apnea, rhythmic movement disorder, teeth grinding, and malocclusion. If tongue biting occurs frequently, it is important to seek medical advice to treat these underlying conditions. A doctor may recommend a sleep study to determine the cause of tongue biting during sleep. This involves recording brainwave activity, eye movement, muscle tone, heart rhythm, and breathing rate to inform appropriate treatment.
If tongue biting results in severe pain, it may be necessary to seek medical attention. Rinsing the mouth with water can help clear blood and debris, allowing for a better view of the injury. Applying pressure with a clean cloth or gauze can help stop bleeding. However, if bleeding persists after 15 minutes of applying pressure, or if there are signs of infection such as swelling, redness, fever, or pus, it is important to see a doctor or dentist. They can examine the size and shape of the wound to determine if stitches are required.
In some cases, tongue biting may be related to dental issues such as misaligned teeth or an enlarged tongue. If this is suspected, it is advisable to consult a dentist for their professional opinion. They may recommend braces or Invisalign to correct bite alignment and prevent further tongue biting. Additionally, a dentist can recommend a suitable mouthguard to protect the tongue and teeth during sleep.
While less common, frequent tongue biting could be related to illicit drug use or smoking. If this is the case, discontinuing drug use or seeking help to quit smoking may resolve the issue. It is important to consult a doctor for guidance and support throughout this process.
