It’s normal to want to put an end to the uncomfortable habit of biting your tongue while you sleep, as it can be quite painful. The best thing to do is to consult with a healthcare professional like a dentist, doctor, or sleep specialist. They can help you figure out what’s going on because frequent tongue biting might be a sign of an underlying issue.
Let’s take a look at some of the common causes behind nighttime tongue biting and some tips to help you prevent it:
1. Address Underlying Medical or Dental Conditions
One of the most common reasons people bite their tongues while sleeping includes:
- Bruxism (Teeth Grinding or Clenching): When your jaw moves unexpectedly, it can cause your tongue to get in the way.
- Solution: If you’ve ever worried about protecting your teeth during the night, a custom-fitted dental mouthguard or night guard from your dental office could be just what you need. It’s a simple solution that not only protects your teeth but also keeps your tongue and cheeks safe from injuries.
- Sleep Apnea: When breathing gets interrupted, it can lead to sudden jaw movements or relaxation of the muscles, which might make it easier to accidentally bite your tongue.
- Solution: If you’re dealing with sleep apnea, there are effective treatments out there. Options like a CPAP machine or an dental appliances can really make a difference and help you get back to restful nights. A sleep study can be very helpful in figuring out what’s going on.
- Nocturnal Seizures: Uncontrolled muscle contractions during a seizure can lead to your jaw clenching down on the tongue.
- Solution: If you’re dealing with seizures, a doctor or neurologist can help by prescribing anti-seizure medication to manage your symptoms.
- Malocclusion (Misaligned Teeth): If your bite is off or if you’ve got some sharp or uneven dental work, it might lead to accidentally biting yourself more often.
- Solution: If your dentist or orthodontist suggests some dental adjustments or orthodontic treatment, it’s just to help get your smile looking its best. They’re here to make sure your teeth are properly aligned.
- Facial Muscle Spasms or Rhythmic Movement Disorder: These are quick and strong movements of the face and jaw muscles.
- Solution: If you’re having trouble sleeping, a sleep specialist or neurologist might suggest trying out a medication like clonazepam to help.
2. General Prevention and Lifestyle Changes
While you’re in the process of getting a professional diagnosis, here are a few steps you might find helpful to try out:
Reduce Stress and Anxiety: Stress can really take a toll on our bodies, often leading to jaw clenching and muscle tension. There are some simple relaxation techniques you can try before bed to help ease that stress. Here are a few to consider:
- Deep breathing exercises.
- Meditation or mindfulness.
- Gentle stretching or yoga.
Practice Good Sleep Hygiene:
- Try to stick to a regular sleep schedule.
- Create a calm, dark, and comfortable sleep environment.
- Avoid caffeine and alcohol as bedtime approaches.
Review Medications: If you’re noticing muscle spasms or feeling restless while you sleep, it’s worth consulting with your doctor about it. Some medications, like certain antidepressants, can sometimes lead to those kinds of side effects. Whether you’re on something new or have been taking medications for a while, it’s always a good idea to keep the lines of communication open.
3. Immediate Relief for a Bitten Tongue
If your tongue is already sore or injured:
- Try rinsing your mouth with warm salt water—just mix 1 teaspoon of salt in 1 cup of warm water. It can really help reduce swelling and promote healing.
- Avoid really hot, spicy, acidic, or crunchy foods for a little while, since they might irritate your injury.
- If you’re feeling some discomfort, it’s okay to grab some over-the-counter pain relievers like acetaminophen or ibuprofen. And don’t forget to apply a soothing gel or ointment made for oral sores.
If you find yourself biting your tongue frequently or it’s getting really painful, especially if you’re also dealing with loud snoring, feeling tired during the day, or having jaw pain, it’s a good idea to reach out to a professional. They can help you figure out what’s going on and get you the right treatment.
Signs You’re Biting Your Tongue While Sleeping
Since you’re unconscious while you sleep, you might not even feel a bite happening. Instead, you’ll likely notice the signs when you wake up, or maybe your partner will spot them first.
Here are some common signs that you might be biting or chewing your tongue while you sleep:
Immediate Morning Signs
- Pain or Soreness: One of the easiest ways to tell something might be off is when you wake up with a sore or painful tongue. It can feel like a little sting or sometimes it might throb more intensely.
- Visible Injuries: You might notice some cuts, lacerations, or smalls sores (also known as ulcers) on your tongue.
- Bleeding: If the bite was pretty serious, you might find some fresh blood on your pillow or even in your mouth when you wake up.
- Swelling: If you’ve bitten your tongue, you might notice that the area looks red or swollen, and it could feel inflamed too.
Chronic or Recurring Signs
- Scalloped Edges (Creanated Tongue): If you’ve been pressing your tongue against your teeth a lot, you might notice that the area looks wavy or has some indentations from your teeth.
- Indentation Marks: You might see some red or white marks, grooves, or indentations on the sides or tip of your tongue where your teeth have been resting or biting down.
- Jaw or Facial Pain: If you find yourself biting your tongue and think it might be related to grinding your teeth, you might notice some discomfort. This can include a sore jaw, headaches, or even some pain in your face or temples.
- Disrupted Sleep: If you’ve ever experienced a really painful bite, it might just shock you awake in the middle of the night—maybe even with a little gasp or shout.
- Difficulty Eating or Speaking: If you’ve got some cuts in your mouth that just won’t quit, you might find it uncomfortable to chew, swallow, or even talk for a few days until the injury begins to heal.
Associated Symptoms
If you find yourself biting your tongue and wonder if it could be linked to a medical condition, you might notice some other signs or symptoms as well. Here’s what to keep an eye out for:
- Loud Snoring or Gasping: Often a sign of sleep apnea.
- Morning Headaches: Also notice it as a sign of bruxism or sleep apnea.
- Unexplained Body Bruises/Injuries: Biting could happen if it’s related to a movement disorder or nocturnal seizures.
If you keep seeing signs like pain, sores, or scalloped edges on your tongue, it’s a good idea to take a closer look at what’s going on while you sleep. If you find yourself biting your tongue often at night, it might be a sign of something else going on, like teeth grinding or a sleep disorder. It’s a good idea to consult with your dentist or doctor about it. They can help uncover what’s behind it and guide you toward the right treatment.
