What is a Tongue Tie? We Explain the Signs, Symptoms & Simple At-Home Tests for a Tongue Tie

What exactly is a tongue tie, and how do you know if you might have one?

In this video, Dr. Lucy Johnson explains what a tongue tie is, why it matters, and how restricted tongue movement can affect your breathing, sleep, oral health, and overall function. Using real patient photos, she shows exactly what a tongue tie looks like and how you can begin to identify possible signs at home.

When you lift your tongue in the mirror, do you see a tight band of tissue pulling toward the tip? That’s called the lingual frenulum, and everyone has one. It’s the small band of tissue that connects the tongue to the floor of the mouth. Its job is important. It helps control tongue movement during speech, swallowing, and normal function.

However, when this tissue extends too far toward the tip of the tongue, it can create restriction. This is what we call a tongue tie. When the tongue cannot move freely, patients may experience a wide range of symptoms including:

• Mouth breathing
• Snoring or obstructive sleep apnea concerns
• Difficulty clearing food from teeth
• Food pouching in the cheeks or gums
• Speech or swallowing challenges
• Tooth positioning or bite concerns
• Neck tension and poor posture

Dr. Johnson also demonstrates simple tongue tie tests you can try at home, including:

• Tongue to roof test: Place the tip of your tongue on the roof of your mouth and open wide. Your mouth opening should be almost the same as when your tongue is relaxed. If it’s much smaller, restriction may be present.
• Tongue extension test: Stick your tongue out as far as possible. Ideally, you should be able to extend it about the width of your thumb.
• Mirror check: Lift your tongue and look underneath. If the tip of your tongue pulls into a heart shape or you see strong tension in the tissue, it may indicate a tongue tie.

These checks can help you identify potential signs at home, but the most accurate way to know is to have an evaluation with a dental professional If you suspect you may have a tongue tie or are experiencing symptoms related to restricted tongue movement, our team at District Dental Surgery is happy to help.
