Curved edges along the sides of the tongue are a common issue among some individuals caused by tongue biting when you sleep.

The easiest way to tell that you have such a condition is if there is a raised, white line on the sides of your tongue. Today, we will look at some possible reasons you might be biting your tongue when you sleep.


High levels of stress can force someone to clench their teeth so hard to the extent of biting their tongue. This can occur either during the day or at night when you sleep. When sleeping, this action can be unknowingly and might result in tongue biting.

Muscle spasm

All humans experience muscle spasms at some point. Some common causes include dehydration and stress. It is a condition that can happen to any muscle of your body.

It causes trembling of the chin when you are asleep and can cause the jaw to clench and bite your tongue; the effect of this condition can be severe or minor.

Enlarged tongue

Some people have an enlarged tongue due to either medical or genetic conditions. When the tongue is too large, such individuals have the possibility of biting the tongue because it protrudes through the teeth. This can occur when they are asleep or bored during the day.

Sleep Bruxism

Sleep bruxism is widely spread among children and young adults. Most children experience teeth grinding as a result of the newly developing teeth, stress that they don’t know yet how to handle, and some other factors that cause this involuntary behavior.

We all know teenagers have a lot of stress, but some don’t know how to tackle them, so at night or even during the day, they tend to grind unknowingly. It might happen without your consent until you realize you have a swollen tongue.

Drug use

Ingestion of chemicals such as nicotine confuses your brain; they keep the mind awake even when you are sleeping. As a result, the brainwaves remain in alert mode, and you might end up unconsciously moving your jaw muscles, thus biting your tongue.

Biblical meaning of biting your tongue when you sleep

Well, the scripture does not address the subject of biting the tongue when asleep directly, but it tackles it in some other ways. The Bible says in Proverbs 17:128 that even a fool is considered wise when they bite their tongue.

This serves as a reminder for us to consider and rethink what we utter, and if it is something that will cause pain to others, it is better to avoid uttering it.

Sometimes, it might be difficult for some of us to keep what we want to say within when we are provoked, but we should always remember that the Bible warns us against this. In James 3:1-5, the tongue is likened to fire and deadly poison, and one can bless or curse by it. This means that, biblically, our tongues hold much power at the spiritual level.

Moreover, Proverbs 18:21 teaches us that the word of the tongue can change one’s life, for it has the power to kill or make alive.

Every word we utter will come to judgment according to the teachings of Jesus in Matthew 12:36-37. In addition, according to Ephesians 4:29, we are only supposed to speak what is constructive to others, and it is our responsibility to turn our words into blessings and not curse others.

What can you do when you keep biting your tongue in your sleep?

You might be biting your tongue frequently when you sleep and are wondering what you can do in such cases; here are a few tips on how to handle this issue.

Wear upper and lower mouthguards

A mouthguard is one of the effective preventive tools against biting your tongue when you are asleep. Moreso, if you are suffering from bruxism, a mouthguard would be helpful in protecting your tongue against your teeth.

Purchasing a well-fitting mouthguard is key as they need to fit in your mouth and teeth to restrict movements in the mouth, making it impossible to brux in a way that could cause damage to your tongue.

Relaxation technique

Anxiety or nervousness can result in tongue biting when asleep or even in a state of boredom. Taking deep breaths and meditating is a relaxing technique that can help calm your mind, helping to minimize this occurrence.


In the case of Malocclusion, you can wear braces to prevent biting your tongue while sleeping. Malocclusion is a condition that results from gaps between the teeth, crowding, or any other condition where your dental formula is not well lined up. Braces will help align the teeth, reducing the risk of biting your tongue.
