Overview 

Ankyloglossia, commonly known as tongue tie, is a condition present from birth where the piece of skin under the tongue (lingual frenum) is shorter or thicker than usual. This can restrict tongue mobility, and in severe cases, may result in a cleft or notched appearance of the tongue.¹ The prevalence of tongue-tie ranges from 0.1% to 10.7% and is more frequently observed in individuals assigned male at birth (AMAB).² While many studies emphasise breastfeeding issues, dental misalignment, limited oral mobility, food accumulation, and psychological distress. The aetiology of ankyloglossia is not fully understood, but genetic factors have been identified. In some cases, improvement may occur naturally with growth and stretching of the frenulum.^3,4

Classification of ankyloglossia according to Kotlow (based on the free tongue length⁵

Doctors sometimes measure how far the tongue can move to decide how serious the tongue-tie is. Here is a simple breakdown: 

• Normal: tongue moves more than 16mm-no problem
• Mild (Class I): 12-16mm-slight restriction
• Moderate (Class II): 8-11mm-noticeable trouble
• Severe (Class III): 3-7mm-major limitation
• Complete (Class IV): Less than 3mm-tongue barely moves

This helps decide if treatment is needed.

Signs and symptoms 

 In Babies:

• Takes a long time to feed or wants to feed very often
• Trouble staying attached during breastfeeding(latching)
• Poor weight gain
• Slurping or clicking sounds while feeding 
• Fussy or upset during feeding
• Can’t open mouth wide

Tongue may look heart-shaped when sticking out in mothers:

• Painfulnipples
• Breast infections(mastitis) due to milk not being fully removed
• Less milk production
• Feeling worn out from constant feeding

Eating and swallowing

As babies grow and start eating solids, a tongue-tie can make it hard to move food around in the mouth. Instead of pulling food in, they may push it out. They might gag, choke, and vomit more often. These children might eat very slowly or very messily, and they often prefer soft foodsThey may also swallow a lot of air while eating(aerophagia), which can make them feel gassy and uncomfortable.⁷

Dental and sleep problems

Tongue-tie can stop the tongue from resting properly at the top of the mouth. This can affect how the jaws grow and how teeth come in, leading to crooked teeth or spacing. It may also cause children and adults to breathe through their mouths instead of their noses, especially at night. Some people with tongue-tie have trouble sleeping well or may even develop snoring or sleep apnoea, where breathing is interrupted during sleep. This happens because the tongue can fall back and block the airway.⁷

Oral hygiene

Normally, the tongue helps to clean leftover food from teeth and gums. When a person has a tongue-tie, the tongue can’t move well, and food gets stuck more easily. This can lead to plaque build-up, cavities, and gum problems like redness or swelling.⁶

Speech issues

Tongue-tie can make it hard to pronounce certain letters clearly. People may struggle with sounds like ‘’s’’, ‘’z’’,’’ t’’,’’d’’,’’j’’, ‘’l’’, ‘’r’’, and others that need the tongue to reach the roof of the mouth or push forward(6). This can make speech less clear and harder to understand.

Social and emotional effects

Being able to speak clearly is important for making friends, doing well in school, and feeling confident. If someone has trouble speaking or feels self-conscious about how their tongue or teeth look, it can affect their self-esteem. This may lead to stress or anxiety in social situations.^9,10

Treatment 

Whether tongue-tie needs treatment depends on how severe it is. Many mild cases don’t need surgery and get better as the child grows. Sometimes, simple exercises or massages can help.

If treatment is needed, these are the options:

• Frenotomy: A quick snip of the tight skin under the tongue (usually done for babies)
• Frenuloplasty A more detailed surgery where the skin is cut and repositioned 
• Frenectomy: Removal of the skin under the tongue completely¹¹

Laser treatments are sometimes used to make healing faster and reduce bleeding. The decision should always be based on how much the tongue-tie affects eating, speaking, or health.

FAQ’s 

Does a tongue-tie need to be fixed?

Not always. Some people do just fine without treatment. It depends on how much it affects feeding, speech, or comfort.

Do tongue-tie go away on its own?

In mild cases, yes. Sometimes, the tongue gets more flexible as a child grows.

When is the best time to treat tongue-tie?

If needed, treatment is often easiest in the first 2 to 6 weeks after birth. Babies adjust more quickly during this time.

Can exercises help with tongue-tie?

Yes, gentle tongue massages and movement exercises can sometimes help, especially in mild cases.

Can tongue-tie change how a child looks?

Yes, if it causes mouth breathing or changes in jaw growth, it might affect the shape of the face or how the teeth grow in.

Is a tongue-tie a birth defect?

It’s a condition that happens before birth when the tongue doesn’t separate fully from the bottom of the mouth. It’s common and treatable.

Summary 

Tongue-tie affects many children and adults in different ways. Some have no problems, while others may need help with feeding, speaking, or dental issues. Treatment isn't always needed and depends on the individual. If there are problems, healthcare providers from different fields (like doctors, dentists, or speech therapists) may work together to decide the best plan. It’s important to have clear methods for spotting and treating tongue-tie so everyone can get the help they need early on.
