Tongue tie is when the bottom of the tongue is attached to the floor of the mouth.
This makes it hard to freely move the tip of your tongue.
Causes, incidence, and risk factors
The exact cause of tongue tie is not known. Your genes may play a role. It tends to run in some families.
The tongue is stuck to the bottom of the mouth by a band of tissue called the lingual frenulum.
In a newborn or infant, the symptoms of tongue tie are similar to the symptoms in a child who is having problems with breast feeding. Symptoms may include:
- Acting irritable or fussy, even after feeding
- Difficulty creating or keeping suction on the nipple. The infant may become tired in 1 or 2 minutes, or fall asleep before eating enough.
- Poor weight gain or weight loss
- Problems latching onto the nipple. The infant may just chew on the nipple instead.
The breastfeeding mother may have problems with breast pain, plugged milk ducts, or painful breasts, and may feel frustrated.
Signs and tests
Most experts do not recommend that health care providers examine newborns for tongue tie unless there are breastfeeding problems.
Most health care providers only consider tongue tie when:
- The mother and baby have had problems starting breastfeeding
- The mother has received at least 2 to 3 days of support from a breastfeeding (lactation) specialist
Most breastfeeding problems can be easily managed with a variety of strategies.
If you run into any problems, talk to person who specializes in breastfeeding. This is called a lactation consultant.
Surgery is rarely needed. Tongue tie surgery is called a frenulotomy. It involves cutting the tissue under the tongue. It is usually done in the doctor's office. Infection or bleeding afterwards are possible, but rare.
Surgery for more severe cases is done in a hospital operating room. A surgical reconstruction procedure called a z-plasty closure may be needed to prevent scar tissue from forming.
On rare occasions, tongue tie has been linked to tooth, swallowing, or speech problems.
