Scalloped Tongue

Causes, Symptoms, and Treatment

November 15, 2024 Written By: Joyce Kahng, DDS

Scalloped tongue is a pretty common issue that can happen to anyone, but it’s often seen in people with specific health challenges. If you grind your teeth at night or struggle with sleep apnea, you might be at higher risk since these conditions put extra pressure on your tongue.

Stress, dehydration, and not getting enough nutrients can also play a role, causing the tongue to swell and making those scalloped edges more noticeable.

What Is a Scalloped Tongue?

A scalloped tongue, also known as a crenated tongue or tongue ridges, is characterized by indentations or wavy edges along the sides of the tongue. These scalloped edges are typically uniform and appear as shallow grooves, often resembling the marks left by teeth pressing against the tongue.

This appearance can vary greatly in severity and is typically painless, though it can sometimes be accompanied by discomfort, depending on underlying conditions.

Common Causes of Scalloped Tongue

Bruxism (Teeth Grinding)

Bruxism, which is when you grind or clench your teeth, can often be the reason behind scalloped tongues. If you find yourself grinding your teeth, particularly while you sleep, your tongue can get pressed against your teeth, creating those wavy edges.

Waking up with a sore jaw or headaches? You might be dealing with bruxism. But don’t worry! There are effective solutions, like using a mouth guard or practicing relaxation techniques, to help reduce that nighttime grinding.

Sleep Apnea and Tongue Enlargement

Sleep apnea doesn’t just mess with your sleep; it can also affect your oral health. When this condition occurs, the muscles around your airway may relax too much, leading to an enlarged tongue due to ongoing pressure or blockage.

This can cause your tongue to press against your teeth, resulting in scalloping. Common signs of sleep apnea include:

  • Loud snoring
  • Choking during the night
  • Feeling drowsy during the day

Seeking the right treatment for sleep apnea can help ease these oral health issues and improve your overall well-being.

Nutritional Deficiencies

Taking care of your tongue is important, and a well-balanced diet plays a big role in keeping it healthy and free from scalloping.

If you’re missing out on essential nutrients like B vitamins and iron, you might notice your tongue swelling up.

Keep an eye out for other signs such as: 

  • Fatigue 
  • Weakness 
  • Pale skin 

These could be hints that your body needs a little extra support.

Adding foods rich in these nutrients to your meals or considering supplements (with advice from a healthcare professional) can be a great way to boost your oral health and overall well-being.

Dehydration and Swelling

Staying hydrated is super important—not just for your overall health, but also for your oral wellness!

When you don’t drink enough water, you risk becoming dehydrated. This can lead to swollen tissues, including your tongue. Swelling can cause your tongue to press against your teeth, resulting in scalloped edges.

To avoid this, try to drink plenty of fluids every day—aim for about eight glasses of water or more.

Genetic and Structural Factors

Sometimes, a scalloped tongue can arise from our genes and the structure of our mouths. If you have a naturally larger tongue or a unique jaw structure, you may be more prone to experiencing this.

These traits often run in families, making it common to see them among relatives. While we can’t change our DNA, being aware of these factors can help you find the right care.

Consider orthodontic treatments or adjustments to feel more comfortable and enhance your oral health.

Other Health Conditions

A scalloped tongue can sometimes indicate underlying health conditions. Here’s a quick look at some associated issues:

  • Hypothyroidism: This condition causes low thyroid hormone production, leading to swelling, including in the tongue.
  • Anxiety: Stress and anxiety may lead to habits like clenching, indirectly causing scalloping.
  • Temporomandibular Joint Disorder (TMJ): TMJ involves issues with the jaw joint and can contribute to teeth grinding.

Symptoms of Scalloped Tongue

A scalloped tongue is usually pretty easy to recognize. You’ll notice indentations or wavy edges along the sides, creating a series of grooves that look quite uniform.

While it might not hurt for most people, some may experience:

  • Soreness
  • Sensitivity
  • Pain in more severe cases

These changes can sometimes make talking or eating a bit uncomfortable.

Associated Symptoms Related to Underlying Conditions

If you’re noticing a scalloped tongue, it might come with some other symptoms indicating deeper health issues.

  • Headaches or jaw pain could be linked to teeth grinding or bruxism. 
  • If swallowing becomes a challenge, this might suggest your tongue is enlarged, which can hint at conditions like sleep apnea.

These symptoms serve as important clues about your health. Regular visits to the dentist can truly make a difference in managing these issues and ensuring your oral health is in check.

Diagnosis of Scalloped Tongue

Noticing a scalloped tongue? It might be a good idea to reach out to a healthcare professional, especially if you’re experiencing persistent discomfort, swelling, or difficulties with everyday activities like speaking or eating.

Watch for other red flags, such as:

  • Excessive tiredness
  • Loud snoring
  • Jaw pain

Diagnostic Steps

When you visit your dentist or doctor, it typically begins with a thorough physical exam and a friendly chat about your medical history. This important first step can help uncover habits like bruxism or any medical conditions that might be affecting your scalloped tongue.

If needed, they might suggest some extra tests such as: 

  • Blood tests to check for nutritional deficiencies 
  • A sleep study to see if sleep apnea is a concern 

Identifying the root cause early on is essential. It can help create a personalized treatment plan, improving not just your oral health but your overall quality of life.

Symptoms of Scalloped Tongue

Identifying a scalloped tongue is simple. Look for indentations along the tongue’s sides, resembling wavy edges. Most times, it’s not painful, but some individuals might feel soreness or sensitivity. In extreme cases, there could be pain, making talking or eating challenging. Accompanying symptoms may point to deeper issues, such as headaches or jaw pain linked to grinding. Difficulty in swallowing may indicate tongue enlargement from conditions like sleep apnea.

Treatment Options for Scalloped Tongue

Managing Underlying Conditions

Bruxism Treatments

Mouthguards, or night guards, are great tools to help stop teeth grinding while you sleep. These custom-fit devices serve as a protective barrier for your teeth.

In addition to using mouthguards, consider incorporating stress management techniques and relaxation exercises into your routine. These practices can significantly reduce how often and how hard you grind your teeth.

Addressing Sleep Apnea

CPAP machines and positional therapy are effective tools that keep your airways open during sleep. These treatments help ease the pressure on your tongue, promoting better oral health.

Correcting Nutritional Deficiencies

Taking care of your tongue is important, and a balanced diet plays a big role in keeping it healthy.

Make sure to include essential nutrients like: 

  • B vitamins 
  • Iron 

These nutrients support not just your tongue, but your overall well-being.

Before starting any new supplements, it’s always a good idea to chat with your healthcare provider. They can help you create a nutrition plan that fits your needs and supports great oral health!

Lifestyle and Habit Changes

Staying Hydrated

One of the simplest ways to take care of a scalloped tongue is to stay well-hydrated. Drinking plenty of water not only promotes good health but can also help reduce tongue swelling.

  • Keep a water bottle handy and take sips throughout the day.
  • Set reminders on your phone to help you hit your hydration goals.

Reducing Salt and Processed Foods

A diet that’s high in sodium can lead to uncomfortable issues, such as swelling and scalloping of the tongue. To help keep your mouth healthy, consider these tips:

  • Cut back on salty snacks and processed foods. 
  • Opt for fresh, whole foods whenever possible. 

Cooking at home is a great way to manage how much salt you use in your meals. Plus, always remember to check the labels on pre-packaged foods to stay aware of their sodium content.

Regular dental visits are really important for keeping an eye on your scalloped tongue and overall oral health. Your dentist can catch any changes early, offering helpful advice and support when necessary.

Dental Appliances and Supportive Treatments

Dental appliances like mouthguards and retainers can truly make a difference in your oral health. They help alleviate pressure on your tongue and keep your jaw aligned by preventing teeth grinding.

Consider these benefits:

  • Prevent teeth grinding: Reduce stress on your teeth and jaw.
  • Jaw alignment: Maintain proper positioning for better comfort.
  • Address scalloping: Improve the overall appearance of your tongue.

It’s a great idea to have a conversation with your dentist about which options might work best for you.
