Why do I keep biting my tongue: When does it happen

To understand the causes of frequent tongue biting, it is important to determine when the action takes place and what activity you are doing. This will let you unearth the reason and help you deal with the problem better.

1. While eating

This is one of the most common actions we perform when accidentally biting our tongue. Sure, we are savoring a delicious meal, and our eating speed is bound to be much faster than usual.

You are chewing on your favorite food, enjoying every bit and taste, and OUCH! You bite your tongue, and the entire experience of enjoying this meal is ruined with utter pain and discomfort.

When this happens once or twice, it’s something you can brush off as a mistake. But if it happens every third or fourth time, you should dig deeper into the vital question of “why do I keep biting my tongue?“.

This happens because of distraction, which breaks the coordination between the mind and actions. Usually, it happens when you are immersed in a thoughtful idea or attempting to speak while eating.

2. While Sleeping

Biting your tongue when you are wide awake is still acceptable as a conscious mistake, but when nighttime tongue biting comes into play, that’s when you should be worried.

Because you are not making any voluntary movements in the state of sleeping, every movement that takes place is bound to be a reason for worry.

The reason for the same varies. Some of those that hail from peer-reviewed studies are given below :

  • Facial Muscle Spasms

Generally observed in children, a facial muscle spasm involves the inability to control the jaw and face muscles when sleeping, which then causes uncontrollable trembling. This rapid movement of the jaw causes one to bite their tongue. The scientific term for this condition is Faciomandibular myoclonus.

  • Bruxism

In simple terms, we know bruxism as teeth grinding. This common problem affects many people at some other point of age: excessive grinding while sleeping can cause tiredness and soreness, typically in the teeth and jaw.

But sometimes, it can also cause small bites on the tongue. You, as the sleeper, will not be able to be aware of this symptom and will often find out about it through the ones sleeping next to or around you because of the cluttering noise that it creates.

  • Nighttime seizures

People who are diagnosed with epilepsy are the ones who tend to go through uncontrollable seizures. These sudden movements of Epileptic seizures can cause cheek biting and similar tongue injuries, which may or may not bleed.

These injuries are usually observed on the foremost part of the tongue – its tip and side. The injuries that form at the side of the tongue tend to affect your speaking ability and hinder your chewing habits too.

  • Sleep Apnea

This is a serious sleep disorder that involves sudden stops and starts in breathing. Tongue biting is not a direct outcome of this disorder but is related to it. People diagnosed with sleep apnea have been observed to have a larger tongue than the usual size.

This causes the mouth to relax and destress much differently than normal. Because of this abnormal tongue relaxing, the mouth’s inner movements are hindered.

Do you have Sleep Apnea?

Look for symptoms such as

  • Excessive sleepiness and tiredness during the daytime.
  • Getting a bad headache first thing in the morning.
  • Sudden gasping for air when sleeping and loud snoring persists for an extended period.

Although, it is still a lot better to consult a doctor first to rule out (or in) if you have this sleep disorder.

  • Rhythmic Movement Disorder

In most cases, children are the ones most affected by Rhythmic Movement Disorder. This involves the person repeating movements such as humming and headbanging. This causes tongue injuries because of the rapidness of the movement. The sudden movements can trick the person off and have them lose control.

  • Lyme disease

This disease is caused due to bacteria, ticks, to be precise. The correlation between Lyme disease and tongue biting is not direct, but the former may affect reflexes and the nervous system, which in turn may play a role in accidentally biting your tongue.

Other than these, a few more symptoms to look to determine if you bite your tongue are:

  • Tongue bleeding with visible red streaks,
  • Swelling on some parts of the tongue,
  • Ulcers form on the tip or sides of the tongue and cuts.

Types of mouthguards vary and need a thorough cleaning to avoid bacteria making their way toward your gum. So, the best option to get one is to consult your dentist to prescribe a suitable mouthguard.
