Diseases reference index «Tongue tie»

Tongue tie is the improper positioning of tongue tissue in the mouth, which restricts the tongue's free movement.


Tongue tie occurs when the tissue on the underside of the front of the tongue is positioned too far forward on the tongue, making it difficult to move the tongue. This tissue is called the lingual frenulum.

If the tissue reaches the tip of the tongue, a V-shaped notch may be seen.

Tongue tie may cause feeding problems, tooth problems, and speech problems.


  • Can't stick the tongue forward
  • Difficulty feeding
  • Excessive attachment of tongue to bottom of the mouth
  • V-shaped notch in tip of tongue

Exams and Tests

A doctor can diagnose this condition during a physical exam. The exam will show that the tongue tissue is attached too far forward.


Surgery is seldom necessary but if it is needed, it involves cutting the abnormally placed tissue. If the child has a mild case of tongue tie, the surgery may be done in the doctor's office. More severe cases are done in a hospital operating room. A surgical reconstruction procedure called a z-plasty closure may be required to prevent scar tissue formation.

Outlook (Prognosis)

Surgery, if performed, is usually successful.

Possible Complications

The complications are rare, but recurrence of tongue tie, tongue swelling, bleeding, infection, and damage to the ducts of the salivary glands may occur.

When to Contact a Medical Professional

If you are concerned that your child may have tongue tie, have your health care provider examine it during a routine well-baby examination.
