How to stop biting tongue while sleeping?

Tongue biting during sleep is a prevalent problem, particularly in children. All you’ll feel is a sharp pain on your tongue that may cause you to wake awake. People with concomitant medical disorders, such as seizures and facial muscular spasms, have a greater incidence. Unfortunately, regardless of how harmless this condition seems, it can progress to a multitude of complications, including ulcers, oral infections, and tongue scalloping.

Tongue biting while sleeping causes

You may bite your tongue in your sleep for a variety of reasons. When a person chews their tongue during the day, they are almost certainly aware. At night, though, you’re more prone to unintentionally bite your tongue. Tongue biting during sleep is usually caused by an underlying medical issue.


Teeth grinding and clenching, often known as bruxism, is a common movement disorder that can impact you while you sleep. It usually affects the teeth and jaws, resulting in discomfort, suffering, and damage. Bruxism, on the other hand, can lead a person to bite their mouth and cheeks. Doctors aren’t sure what causes bruxism, but they believe it has to do with dreaming or being aroused when sleeping.

Facial muscle spasms

Tongue biting can be caused by facial and jaw muscular contractions. This disorder is most frequent in youngsters, and it causes the chin to shake uncontrollably as they sleep.

During sleep, people with these spasms are unable to regulate their face and jaw muscles, and they frequently bite their tongues. “Facio mandibular myoclonus” is another name for this disease.

Illicit drug use

MDMA, popularly known as “molly” or “ecstasy,” is a psychoactive substance that generates great euphoria. It also appears to induce bruxism, a condition in which the teeth, cheeks, and tongue are severely damaged.

While specialists aren’t sure what causes bruxism in MDMA users, some speculate that the drug may increase the impulse to bite or chew. MDMA may cause a reduction in the capacity to keep the jaws open.

Lyme disease

Lyme disease is a condition that is not well understood. However, it appears to affect the central nervous system as well as physical reactions. This may cause you to bite your tongue or cheeks unintentionally. Other Lyme disease symptoms include:

abnormal sensitivities to heat and cold


slurred speech

frequent diarrhea

vision changes

generalized pain and tingling

Nighttime seizures

Tongue biting is a typical symptom of nighttime seizures. During a seizure, people with epilepsy lose control of their body. They may subconsciously bite down on their tongue as a result of this. Bite marks are most commonly found on the tongue’s tip and sides. 

Rhythmic movement disorder

When a person is sleepy or sleeping, they have a rhythmic movement problem. It causes a person’s physical motions to be repeated over and over again. This illness primarily affects youngsters. It may lead them to make humming sounds, rocking and head pounding motions, or rolling. These motions may be quick, resulting in tongue biting.

Sleep apnea

Although tongue biting is not caused by sleep apnea, it is frequent in many persons with the condition. This is due to the fact that patients with sleep apnea frequently have huge tongues or mouth muscles that relax unnaturally during sleep.

Relaxed muscles and a large tongue can lead to tongue biting. Other signs of sleep apnea include:

loud snoring

gasping for air during sleep

morning headache

excessive daytime sleepiness


Some people have misalignments, which can lead to a lot of dental problems. Those with overbites or underbites, as well as crowded teeth, are more likely to bite their lips and tongue.

The signs and symptoms of tongue biting during sleep

Signs and symptoms that indicate tongue biting, include:

Tongue bleeding

Edema (i.e., swelling) of the tongue

Unusual redness of the tongue

Pain during the next morning

Cuts or marks of teeth on your tongue

Ulcers on the tongue

Scalloped raw edges on the tongue

How can I treat a bitten tongue?

A bitten tongue can be treated in a number of different ways. The way you treat the problem will depend on why you bite your tongue. More serious underlying reasons, such as epilepsy, may necessitate further therapy.

Apply ice to the affected area

If you have bite injuries to your tongue, such as swelling, wounds, or redness, ice can help treat the afflicted region. Applying ice or a cold compress to the region will numb the tongue and lessen discomfort, as well as aid to reduce swelling and inflammation.

Rinse your mouth with salty water

If you have an open wound, it’s a good idea to rinse your mouth for 20 seconds with warm, salty water. If required, repeat the procedure. This eliminates bacteria, prevents infection, and helps the body heal faster.

Avoid spicy and hot foods

Spicy or hot meals will make your pain worse, especially if you have an open or new wound. These foods can also cause tongue irritation, making it more likely for you to bite your tongue. Until your tongue recovers, try to eat soft, mild meals that don’t need much chewing.

See a doctor

If you think you’ve done substantial harm to your tongue or if the pain is unbearable, see a doctor. They can examine your mouth and help identify the source of your tongue biting problem This might help you decide on the best possible treatment.

How to stop biting tongue in sleep?

If you’ve experienced tongue biting during sleep in the past, there are some things you can do to prevent it from happening in the future.

Sleep study

To cure tongue biting, you must first address any underlying issues that are causing it. One option to get to the bottom of your problem is to ask your doctor for a referral to a specialist who can do a sleep study.

This includes staying at a sleep institution for one to two nights. A sleep specialist will use electrodes and monitors to capture some of your physiological processes.

Your doctor may be able to figure out what’s causing you to bite your tongue by listening to recordings of your brainwave activity, eye movement, muscular tone, heart rhythm, and breathing rate. They can then suggest a therapy that is right for you.


Wearing a mouthguard helps avoid future injuries for many persons who bite their tongue. Because each person’s mouth is unique, see a dentist or doctor to determine which type of mouthguard is right for you. You might wish to obtain a personalised mouthguard that fits your teeth exactly. You may also go with a less priced, non-customized option.

Reduce stress

Stress is a common cause of nightly bruxism, which leads to tongue biting. Lower your stress levels over the day to reduce your chances of tongue biting. If you’re not feeling as relaxed as you’d like, try some relaxation techniques such as deep breathing, meditation, or yoga.

Don’t use illegal drugs

Avoid using illegal substances like MDMA, which might make you more prone to bruxism. The more you take MDMA and the more often you use it, the more likely you are to have unfavourable side effects.


If you’re taking antiseizure medication, ensuring you take it as directed will help you avoid seizures and tongue biting. If you’re still having seizures or biting your tongue while taking medicine, talk to your doctor about changing your dose.

Treating a bit tongue at home

If the tongue bite is minor, you can treat it at home. Follow these steps to minimize pain and ensure the injury heals properly:

Wear latex gloves or wash your hands with soap and water.

Rinse your mouth with water to help you view the damage better.

Stop the bleeding by applying pressure to the wound with gauze or a cloth.

If there is any swelling, use ice or a cold compress wrapped in a small towel to the outside of the lips or mouth.

If bleeding persists or you discover a noticeable deformity, evidence of infection, or fresh bleeding, see a doctor.

If the injury is severe, make sure to follow a doctor’s advice as well as the home remedies listed below.

Soft, easy-to-swallow meals are recommended.

Reduce discomfort and swelling using an over-the-counter pain treatment such acetaminophen (Tylenol) or ibuprofen (Advil).

Several times a day, apply a cold compress to the afflicted region for five minutes. You may also eat an ice cube or a fruit-flavored ice pop.

To relieve discomfort and keep the incision clean, rinse your mouth with a saltwater solution after eating. 1 teaspoon non-iodized salt to 1 cup warm water to produce a saltwater solution
