Quick answer: A scalloped tongue is a tongue with wavy, rippled, or indented edges, often shaped by the tongue pressing against the teeth. Common causes include dehydration, anxiety and teeth clenching, hypothyroidism, sleep apnea, and nutritional deficiencies. Scalloped tongue itself is benign, and treatment focuses on the underlying cause, from drinking more water to managing anxiety, treating a thyroid condition, or addressing sleep apnea. See a dentist if the scalloping is frequent, uncomfortable, or you’re unsure of the cause.
So, you are brushing your teeth and cleaning your tongue, and you notice that your tongue isn’t as smooth along the sides as it used to be.
“What are these waves?” you might think.
It’s a scalloped tongue.
Do you need to be worried? No.
Is it benign? Yes.
Do you need treatment? Yes, though the right treatment depends entirely on what’s causing it.
This blog discusses scalloped (or indented) tongue in detail, including its causes, symptoms, and treatment options. Book an appointment with Peace of Mind Dental Studio for a quick diagnosis.

Understanding Scalloped Tongue
Your tongue is supposed to be pink, moist, and smooth. However, when something is off elsewhere in your body, it’s often reflected in your mouth, sometimes through swelling or indentation on the tongue. A scalloped, or indented, tongue has ripples, waves, or notches along the sides, making it look distinct from a normal, smooth tongue.
This isn’t something to panic about, but it is worth having evaluated so you know what’s driving it.
Causes of Scalloped Tongue
Are you wondering what’s causing the ripples on your tongue? There are several possible reasons.
| Cause | How it leads to scalloping |
|---|---|
| Anxiety | Anxiety affects the body physically as well as mentally. Fidgeting, labored breathing, and repeatedly clenching and unclenching the jaw can all press the tongue against the teeth and cause scalloping. |
| Dehydration | Even a small water shortage in the body can affect it in unusual ways, including causing the tongue to swell slightly or ripple along its sides. |
| Hypothyroidism | A condition in which thyroid hormone levels are lower than normal, which can lead to several health effects, including swelling of the tongue. |
| Sleep apnea | The tongue relaxes too much during sleep and gets caught between the teeth, causing an indentation. Sleep apnea is a serious condition also linked to type 2 diabetes, high blood pressure, and abnormal cholesterol. |
| Nutritional deficiencies | Not eating a balanced diet, or lacking essential nutrients, can become visible through a ridged or scalloped tongue. |
Hypothyroidism and Scalloped Tongue
Hypothyroidism is a common cause of scalloped tongue. If you have a scalloped tongue and haven’t had your thyroid tested before, it’s worth bringing up with a dentist or doctor.
At Peace of Mind Dental Studio, we examine patients thoroughly to understand the symptoms and severity of a scalloped tongue and help identify the underlying reason. If hypothyroidism seems likely, we’ll advise a thyroid examination, which you should follow up on with your physician.
It’s also important to be honest and transparent about your overall health, medications, and medical history, including conditions like hypothyroidism, when visiting Peace of Mind Dental Studio in Chandler, so we can recommend the right next step.
Expert insight from Dr. Jeremy Silverman, DMD: “Scalloped tongue itself is never the real diagnosis; it’s a clue pointing toward something else, whether that’s dehydration, clenching from stress, or a thyroid issue that hasn’t been caught yet. That’s why I focus less on the shape of the tongue and more on the pattern of symptoms around it before recommending next steps.”
Scalloped Tongue Treatment Options
Scalloped tongue treatment depends on the cause of the problem, so treatment is tied directly to it.
| Cause | Treatment approach |
|---|---|
| Dehydration | Start by drinking plenty of water and fluids, and see if the condition improves. |
| Anxiety | Anti-anxiety approaches, discussed with your doctor, can help if stress and clenching are the driving factor. |
| Hypothyroidism | A thyroid test is needed to confirm the diagnosis; if positive, the right medication can help resolve the scalloping over time. |
| Sleep apnea | A CPAP machine, which regulates the airway during sleep, is the standard treatment and can also relieve the pressure on the tongue. |
The best way to address an indented tongue is to consult Peace of Mind Dental Studio so we can help determine the cause and guide you toward the right treatment, including a custom mouthguard if nighttime clenching is contributing to the problem.

Scalloped Tongue: A Common, Usually Overlooked Sign
A scalloped tongue isn’t an everyday topic of conversation, but it’s more common than people realize, and it’s caused by the factors above rather than being random. It’s a benign condition, and many people don’t even notice the changed shape of their tongue. However, if it causes real discomfort or pain, treatment becomes worthwhile.
