Tongue tie overview

Overview

Tongue tie (medically called ankyloglossia) is a condition present at birth where the strip of skin under the tongue (the frenulum) is shorter or tighter than usual. This can limit how much the tongue can move.

Tongue tie is fairly common. Studies suggest it occurs in about 4% to 11% of newborns. Many mild cases go unnoticed.

Tongue tie affects babies and young children, but it can also be seen in older children and adults who were not treated earlier. It occurs slightly more often in boys than in girls.

Symptoms

Common symptoms

• Difficulty lifting the tongue to the upper teeth or roof of the mouth
• Trouble moving the tongue side to side
• A notched or heart-shaped tongue when sticking it out
• Problems with breastfeeding in babies, such as poor latch, slipping off the breast, or prolonged feeding

Symptoms in children

• Speech difficulties, especially with sounds like 't', 'd', 'n', 'l', 's', and 'z'
• Difficulty licking an ice cream cone or cleaning food off the teeth
• Problems with swallowing certain foods
• Frustration during mealtimes or avoidance of certain foods

Symptoms in older adults

• Chronic jaw pain or clicking in the jaw
• Tension headaches related to tight mouth muscles
• Difficulty with kissing or licking lips
• Dental issues like gum recession or cavities on lower front teeth due to poor cleaning

Causes

Main causes

• Tongue tie is caused by a short, tight band of tissue (frenulum) that connects the tongue to the floor of the mouth. This happens during fetal development, and the exact reason is not fully understood.

Risk factors

• Tongue tie can run in families (genetic link).
• Some studies suggest a higher chance in babies born to mothers who used certain fertility treatments, but more research is needed.

When to see a doctor

See a doctor urgently if:

• If your baby is not feeding well, has poor weight gain, or you see signs of dehydration (fewer wet diapers, dry lips, sunken soft spot on head).
• If you notice pain, swelling, or discharge after a tongue tie procedure.

Book a routine appointment if:

• If your child has ongoing speech difficulties that worry you.
• If breastfeeding is painful for you as a mother despite trying support techniques.
• If you or your child have dental problems or jaw pain that might be related to tongue mobility.

Diagnosis

A healthcare provider can diagnose tongue tie by looking at and feeling under the tongue during a physical exam. They will check how far the tongue can move and the appearance of the frenulum.

Tests that may be done

• A physical examination of the mouth and tongue
• Assessment of feeding (in babies) to see if tongue movement is affecting latch

What to expect at your appointment

The diagnosis is usually quick and painless. For babies, the doctor or a lactation consultant may watch a feeding session. The provider will explain what they find and discuss whether treatment might help. No special scans or blood tests are needed.

Treatment

Treatment for tongue tie depends on whether it is causing problems. If there are no issues, no treatment is needed. When symptoms affect feeding, speech, or oral hygiene, options are available.

Self-care at home

• For breastfeeding issues, work with a lactation consultant to try different positions and latch techniques.
• Perform gentle tongue stretches as advised by a specialist (if approved by your healthcare provider).
• Maintain good oral hygiene – brush teeth carefully and clean under the tongue if possible.

Medical treatments

A common treatment is a frenulotomy – a quick procedure where the doctor snips the tight frenulum to free the tongue. This is often done in a doctor's office with local numbing (or without in very young babies) and usually takes seconds. Healing is rapid. In more complex cases, a procedure called frenuloplasty (surgical release with stitches) may be recommended.

When is surgery considered?

Surgery (frenuloplasty) might be considered if the tongue tie is very thick or if a simple snip was not successful. It is also used in older children or adults when the frenulum is too tight for a simple cut. The decision is always made with your healthcare provider after discussing the risks and benefits.

Living with this condition

Most people with tongue tie live normally without any special adjustments. However, if you or your child has symptoms, small changes can help. Babies may need extra support with feeding positions. Older children and adults might benefit from speech therapy or dental care tailored to their tongue mobility.

Lifestyle tips

• Practice tongue exercises if recommended by a speech therapist or dentist.
• Be patient with feeding – sometimes small breaks during breastfeeding help.
• Encourage good oral hygiene – a tongue with limited movement can miss cleaning food particles, so extra attention is needed.

Diet and exercise

No special diet is needed, but if your child has difficulty eating certain foods (like round, slippery foods), you can cut them into smaller, safer pieces. For adults, if jaw pain occurs, gentle jaw stretches may help. Staying hydrated and eating a balanced diet supports overall oral health.

Mental health and emotional wellbeing

Living with an untreated tongue tie that causes feeding problems or speech issues can be stressful for both the child and the family. Parents may feel anxious or frustrated. It is important to talk about these feelings with a healthcare provider or a support group. If you feel overwhelmed, consider speaking with a mental health professional. For immediate crisis support, reach out to your local emergency number or a crisis helpline.

Prevention

Tongue tie cannot be prevented – it is a variation of normal development that happens before birth. There is nothing a parent can do to cause or prevent it.

Complications

If left untreated

• Persistent difficulty with breastfeeding, leading to poor weight gain in babies or early weaning.
• Speech problems that may need extra therapy.
• Dental problems such as tooth decay or gum disease from poor cleaning under the tongue.
• Jaw pain or headaches from compensating tongue movements.
• Social or emotional difficulties if speech or eating habits cause embarrassment.

Long-term outlook

The outlook for tongue tie is very good. Many children and adults have no problems at all. When treatment is needed, it is usually simple and effective, with quick healing and significant improvement in symptoms. Even without treatment, many people adapt well. With proper support and care, most individuals with tongue tie thrive.
