Tongue Ties in Adults: What They Look Like & How to Fix Them

You're healthy and active and you've committed to living a clean lifestyle—eating clean, exercising, and making sleep a priority. But despite your best efforts, you're still waking up tired from restless sleep, feel fatigued throughout the day, and catch yourself breathing through your open mouth.

What if the root cause of these issues isn't your health routine but something as simple—and often overlooked —as your tongue?

A Tongue tie, or ankyloglossia , isn't just a concern for babies; it can quietly affect adults, too with big consequences. A tongue tie occurs when the tissue under your tongue (the frenulum) is too tight, limiting its movement. This restriction can lead to chronic mouth breathing, poor sleep, neck and back pain, grinding of teeth and painful jaws, and other issues that sap your energy and impact your wellness.

At Northstar Lip and Tongue Tie Center , we specialize in diagnosing and treating tongue ties in adults, helping you achieve optimal function so you can breathe, eat, and sleep better. Here's what you need to know about tongue ties as an adult—and how addressing this often-missed issue can transform your health.

What Are Tongue Ties in Adults?

Annotated anatomy of an adult tongue tie — restricted lingual frenulum tethering the tongue to the floor of the mouth — A tight frenulum under the tongue restricts movement and impacts overall health.

A tongue tie, or ankyloglossia, occurs when the tissue connecting the tongue to the floor of the mouth (the lingual frenulum) is too tight, short, or thick limiting the tongue's range of motion. While it's often identified in infants struggling with breastfeeding, many cases are overlooked and persist into adulthood, causing subtle but significant health challenges.

In adults, a tongue tie can lead to:

Mouth Breathing: This disrupts proper nasal breathing, which is essential for restful sleep and energy. Mouth breathing "results in the mouth becoming dry. This increases the risk of mouth and throat infections."
Chronic Fatigue: Poor oxygen exchange during sleep can leave you waking up groggy and unrefreshed.
Neck and Jaw Tension: Restricted tongue movement can contribute to muscle imbalances and TMJ pain. To learn more, read my post titled Tongue Ties in Adults: The Hidden Cause of TMJ Pain, Neck Tension, and Mouth Breathing .
Teeth Grinding: Clenching and grinding, often linked to airway issues, can worsen oral health.
Swallowing Difficulty: Limited tongue mobility makes it difficult to swallow pills or large bites of food.

These symptoms often go undiagnosed or are attributed to other factors. However, the tongue's position and function are critical to your overall health.

What Does a Tongue Tie Look Like in Adults?

A tongue tie can vary in appearance and severity. Here's what to look for:

Tight or Thick Tissue: When you lift up your tongue you might see a fold of tissue pulling the tongue to the floor of the mouth. The closer the fold is to the tip of the tongue, the more noticeable the tie.

Cupping Shaped Tongue: When you lift up your tongue, it has a cup like appearance with the sides elevating higher than the middle.

Heart-Shaped Tongue: When sticking your tongue straight out of the mouth, the tip of the tongue may appear notched or heart-shaped.

Limited Tongue Movement: If you struggle to lift your tongue or stick it out beyond your lower lip, it could be a sign of a restriction.

Keep in mind that not all ties are visibly obvious, like the ones at the tip of the tongue. Some are located further back in the mouth which can be harder to see but may still cause significant issues. A trained professional can assess you for both visible and hidden ties. "Diagnosis of tongue tie is dependent on tongue structure, free mobility of the tongue, and functionality of the tongue." Bottom line, not only does the appearance of the tongue matter, but also how the tongue moves and functions.

How a Tongue Tie Affects Your Breathing, Sleep, and Energy

Comparison of a person sleeping with mouth open versus mouth closed — Mouth breathing during sleep disrupts energy and recovery; nasal breathing supports better health.

Your tongue plays a central role in how you breathe and sleep. "Upper airway patency is a core component in the patho-physiology of Obstructive Sleep Apnea. Accumulating evidence suggests that the tongue, which is the largest muscle group in the upper airway plays an important role in maintaining patency of the oro-pharynx." The optimal position of the tongue during sleep is resting naturally against the roof of the mouth. In this position, it supports nasal breathing and keeps your airway open while your mouth is closed. However, a tongue tie can prevent this ideal posture, forcing you into mouth breathing.

Mouth breathing disrupts:

Oxygen Intake: Nasal breathing produces nitric oxide, which improves oxygen efficiency. Mouth breathing bypasses this process, leading to less restorative sleep, heart disease, and strokes.
Tonsillar Size: Mouth breathing may be a factor in tonsillar enlargement.
Normal Facial Growth: If left untreated, mouth breathers develop long, narrow faces, narrow mouths, high palatal vaults, dental malocclusion, gummy smiles.
Airway Stability: Poor tongue posture can contribute to snoring or sleep apnea symptoms, even if undiagnosed.
Sleep Quality: Fragmented sleep leaves you feeling fatigued and unable to fully recharge.

Over time, these issues can take a toll, leading to chronic fatigue, brain fog, and reduced performance—despite all your efforts to prioritize health and wellness.
