17931 Tongue Tie Ankyloglossia

Overview

Tongue-tie, also called ankyloglossia, is a condition present from birth that limits how well the tongue can move. A tight or short band of tissue (the lingual frenulum) connects the floor of the mouth to the bottom of the tongue. This can make it hard for babies to breastfeed, and later in life may affect speech, eating, and oral hygiene.

Yes, tongue-tie is a common condition. Studies suggest it affects about 4 to 11 in every 100 babies.

Tongue-tie can affect people of any age, but it is most often noticed in babies and young children. It is seen more often in boys than in girls.

Symptoms

Common symptoms

• Difficulty lifting the tongue to touch the roof of the mouth
• Trouble moving the tongue from side to side
• The tip of the tongue may look notched or heart-shaped when stuck out
• A visible tight band under the tongue
• In babies, trouble latching onto the breast or bottle

Symptoms in children

• Poor weight gain or slow growth
• Fussiness during feeding or taking a long time to feed
• Speech difficulties, especially with sounds like 't', 'd', 'n', 'l', and 's'
• Trouble licking an ice cream cone or cleaning food from their teeth
• Difficulty sticking the tongue out past the lower lip

Symptoms in older adults

• Ongoing speech difficulties that may not have been diagnosed earlier
• Poor oral hygiene because the tongue can't clean food from around the teeth
• Gum problems or tooth decay
• Trouble wearing dentures due to restricted tongue movement
• Challenges with certain foods, like licking or swallowing smoothly

Causes

Main causes

• Tongue-tie happens when the lingual frenulum (the tissue connecting the tongue to the floor of the mouth) is too short or too tight.
• The exact cause is usually unknown, but it is present at birth and is not caused by anything a parent did or did not do.
• It may have a genetic link and can run in families.

Risk factors

• Family history of tongue-tie or other oral conditions
• Being male (boys are more likely to have tongue-tie than girls)
• Certain genetic conditions can be associated with tongue-tie, though this is uncommon

When to see a doctor

See a doctor urgently if:

• If a baby is not feeding well and is not gaining weight
• If there are any signs of dehydration, like fewer wet nappies or dry mouth
• If you notice bleeding, swelling, or a wound under the tongue

Book a routine appointment if:

• If you are worried about breastfeeding or bottle feeding because of tongue-tie
• If your child has speech difficulties that may be related to tongue movement
• If an older child or adult has trouble with oral hygiene, eating, or dentures and you suspect tongue-tie

Diagnosis

Tongue-tie is diagnosed by a physical examination. A doctor, nurse, or health visitor will look into the mouth, examine the band of tissue, and watch how the tongue moves. This is usually a simple and painless check.

Tests that may be done

• A visual examination of the mouth and tongue
• Observation of tongue movement while the person is asked to lift, stick out, or move the tongue side to side
• In babies, an assessment during feeding may be done to see if tongue-tie is affecting latching

What to expect at your appointment

The examination is usually quick and done in a clinic or GP surgery. No special equipment or blood tests are needed. The doctor may ask about feeding patterns, speech concerns, or any symptoms you have noticed. If needed, they may refer you to a specialist for further advice or treatment.

Treatment

Treatment for tongue-tie is not always necessary. If it is causing no problems, many doctors recommend simply watching and waiting. If it does cause difficulties — like trouble feeding, speech problems, or oral hygiene issues — there are options to help. Treatment decisions are always made together with a qualified healthcare provider.

Self-care at home

• For breastfeeding mothers, try different latch positions to make feeding more comfortable
• Keep the area under the tongue clean by wiping gently, especially after feeding
• For older children and adults, practice regular teeth brushing and flossing to avoid buildup around the lower teeth
• Speak with a speech and language therapist if speech sounds are difficult

Medical treatments

Medical treatment focuses on improving tongue movement. In babies, a minor procedure called a frenotomy (or a frenectomy) can be offered. This involves gently dividing the tight band of tissue with sterile scissors or a laser. It is usually quick, causes little or no pain, and often helps with feeding right away. In older children or adults, similar procedures may be done under local anaesthetic. Antibiotics or painkillers are not routinely needed, and specific medicines are not used as a cure for tongue-tie.

When is surgery considered?

Surgery may be recommended if tongue-tie is clearly affecting a baby's ability to feed and weight gain, or if it causes speech problems, dental issues, or difficulty wearing dentures in older people. The procedure is simple and low-risk, but it is only offered after a proper assessment by a healthcare professional.

Living with this condition

For most people, living with tongue-tie means paying a little extra attention to feeding, speech, and oral hygiene. If you have a baby, you may need to try different feeding positions and monitor weight gain. As children grow, watch for any speech delays and encourage good tooth brushing.

Lifestyle tips

• Encourage toddlers and children to do fun tongue exercises, like licking a lollipop or moving the tongue to touch different spots in the mouth
• Maintain a regular routine of brushing teeth twice a day and flossing
• If you wear dentures, keep regular dental check-ups to ensure a proper fit

Diet and exercise

There are no specific dietary restrictions for tongue-tie. In babies, breastfeeding or bottle feeding can be harder, but with support this usually improves. Older children and adults can eat a normal diet, though they may find some challenging foods (like ice cream cones or licking a yoghurt lid) a bit awkward. No special exercise is needed unless recommended by a therapist.

Mental health and emotional wellbeing

Tongue-tie can be stressful for parents and families, especially if feeding is difficult in the early days. Children with speech difficulties may feel frustrated or self-conscious, and older children or adults may feel embarrassed about their speech. These feelings are normal. Reassurance, support, and treatment where needed can make a big difference.

Prevention

Tongue-tie cannot be prevented. It is a condition that develops before birth, and it is not caused by anything a parent did or did not do. There is no known way to stop it from happening, but the effects of tongue-tie can be managed and treated.

Vaccines

There is no vaccine to prevent tongue-tie, and vaccination is not related to this condition.

Screening programmes

There is no routine screening test for tongue-tie in the general population. It is usually noticed during a newborn physical examination, or later when a parent or healthcare professional spots feeding or speech issues. If you have concerns, ask your healthcare provider to look.

Complications

If left untreated

• In babies, feeding difficulties may lead to poor weight gain or dehydration
• Older children may have speech problems that affect confidence or learning
• The tongue may not be able to clean the teeth properly, raising the risk of tooth decay and gum disease
• In adults, dentures may be difficult to fit or wear comfortably

Long-term outlook

The outlook for tongue-tie is good. Many children outgrow the worst of it as their mouth grows, and when treatment is needed — such as a simple frenotomy — it is usually very quick and effective. With the right support, most people with tongue-tie go on to feed, speak, and live normally without long-term problems.
