Have you ever taken a close look at your tongue and noticed unusual indentations along the edges? If so, you may be experiencing a condition known as a scalloped tongue. While it might sound alarming, it’s often harmless and painless — any pain and discomfort is usually linked to underlying causes and not the scalloped tongue itself.
So, what causes the wavy tongue? In this article about scalloped tongue, we look into the causes of the condition, treatment options, and when you should seek treatment to help restore comfort to your oral health.
Causes of Scalloped Tongue
Here are the common causes of a scalloped tongue.
Teeth Grinding or Clenching (Bruxism)
One of the main causes of a scalloped tongue is bruxism, a condition characterized by unconsciously grinding or clenching of teeth during sleep. The grinding can cause pressure build-up, which will push the sides of your tongue against your teeth. Over time, the condition causes a scalloped or wavy appearance on the edges of the tongue.
People with bruxism may experience frequent headaches, clicking sounds in the jaw, and jaw pain, especially in the morning. The constant pressure doesn’t just affect your tongue’s appearance. If left untreated, it can also result in tooth damage, jaw disorders, and chronic discomfort.
Sleep Apnea
Obstructive sleep apnea causes repeated interruptions to normal breathing during sleep. People with larger tongues and relaxed mouth muscles may experience obstructed airflow during sleep, which can cause sleep apnea.
When breathing pauses during sleep, the tongue will press against the teeth in an attempt to keep the airways open. The repeated pressing of the tongue against the teeth causes the indentations along the edges of the tongue.
Some common signs of sleep apnea include waking up gasping for air, loud snoring, daytime fatigue and sleepiness, and morning headaches.
Beyond the scalloped edges, untreated sleep apnea may lead to health risks such as hypertension, stroke and heart disease. Spotting a scalloped tongue could be an early clue that there’s more going on than just a sleeping disorder.
Genetic Conditions
Certain genetic conditions can naturally cause changes in tongue size and shape, resulting in a scalloped appearance. For example, people with Down Syndrome or Ehlers-Danlos syndrome often have larger tongues or weaker connective tissues, which can cause the tongue to press against the teeth.
Common genetic conditions linked to scalloped tongues include:
- Down syndrome: enlarged tongue and low muscle tone
- Ehlers-Danlos syndrome: affects connective tissues, including those in the mouth
- Amyloidosis: buildup of proteins in organs, including the tongue
Anxiety and Stress
Anxiety and stress can lead to a scalloped tongue. It’s common to unintentionally clench your jaw when stressed, which leads to pressing the tongue against the teeth or developing bruxism. Over time, these habits can cause those distinctive scalloped edges.
Treatment Options for Scalloped Tongue
The treatment for a scalloped tongue typically focuses on addressing the underlying cause. Here’s how different treatment paths can help smooth things out:
Managing Teeth Grinding
If teeth grinding is the reason you have a scalloped tongue, custom mouthguards can help protect your teeth and reduce pressure on your tongue while sleeping. In some cases, correcting bite alignment can also help reduce teeth grinding during sleep.
Addressing Sleep Apnea
When sleep apnea is the reason behind a scalloped tongue, your treatment plan will focus on keeping the airways open during sleep. One of the most common approaches is CPAP therapy, which uses a Continuous Positive Airway Pressure machine to help maintain steady airflow throughout the night.
Besides, lifestyle changes like losing weight, quitting smoking, or sleeping on your side can make a big difference in easing sleep apnea symptoms and, in turn, relieving tongue scalloping.
Managing Genetic Conditions
For individuals with genetic conditions that cause a scalloped tongue, supportive care can help manage oral health. Regular dental checkups, speech therapy, and ongoing medical monitoring are crucial for maintaining overall health.
In some cases, orthodontic treatments or specialized oral appliances may be necessary to address alignment issues. If need be, tongue reduction surgery may be recommended to reduce the size of the tongue and correct its shape.
Reducing Anxiety and Stress
Stress and anxiety increase jaw-clenching habits, so relaxation techniques can help curb these behaviors. Mindfulness, meditation, and deep breathing exercises are excellent ways to reduce stress and prevent further pressure on the tongue.
For more persistent anxiety, cognitive-behavioral therapy (CBT) or counseling can help address the root cause and ease tension both in your mind and in your jaw.
In Conclusion
While a scalloped tongue is harmless in itself, it could be a sign that there’s an underlying issue that needs specialized attention. You can maintain a healthy mouth by addressing the root cause, whether through professional treatment plans or lifestyle changes.
If you notice your tongue becoming scalloped, it’s best to seek medical attention to check for potential underlying causes.
