Tongue-tie (ankyloglossia) is a problem with a thin strip of tissue under the tongue. This tissue is called the frenulum. It connects from the underside of the tongue to the floor of the mouth. You can see it if you look under your tongue in a mirror. Some children are born with a frenulum that is too short and thick. This can cause problems with speech and feeding. In other cases, it may not cause a problem.
The frenulum may attach to the tip of the tongue instead of lower down under the tongue. The tongue then can’t move normally. Your child may have trouble sticking his or her tongue out, moving it from side to side, or bending it to touch the upper teeth. The tongue often has a notch at its tip. These problems can cause trouble with feeding as a baby and speaking as your child gets older.
Tongue-tie is different in each child. The condition is divided into classes. They are based on how well the tongue can move. Class I is mild, class II is moderate, class III is severe, and in class IV the tongue can hardly move at all.
What causes tongue-tie?
Doctors aren’t sure exactly what causes the frenulum to form this way. Tongue-tie runs in some families. Your child may have a higher risk for tongue-tie if you or other family members had it.
Symptoms of tongue-tie
Many babies don’t have any symptoms. Others may have problems such as:
Once your baby gets older:
A gap between the bottom 2 front teeth
Trouble making certain sounds, such as “t,” “d,” “z,” “s,” “th,” “n,” and “l.”
In rare cases, a child with tongue-tie may have other problems, like cleft lip or cleft palate. These can cause other symptoms.
In later years, tongue-tie can make it hard for your child to do some activities, such as lick an ice cream cone, play a wind instrument, or kiss.
Tongue-tie may be found when looking for causes of a baby’s breastfeeding problems. A healthcare provider will ask about your child’s medical history and give him or her a physical exam. The healthcare provider will carefully check your child’s tongue and its movements. He or she might advise that your child see a specialist who treats tongue-tie. For example, an ear, nose, and throat doctor.
Treatment for tongue-tie
Your child may not need treatment if he or she has no symptoms or mild symptoms. In some children, most or all symptoms go away over time. Between ages 6 months and 6 years, the frenulum naturally moves backward. This may solve the problem of mild tongue-tie. Or, your child may find ways to work around the problem. Symptoms may be less likely to go away if your child has more serious tongue-tie.
If your child has trouble breastfeeding, your healthcare provider may advise working with a breastfeeding specialist (lactation consultant). If that doesn’t work, your child may need surgery.
If your child is older, he or she may need to see a speech therapist. This specialist will test your child’s speech. The specialist may advise speech therapy. Or he or she may advise surgery.
A simple surgery called a frenotomy (also called a frenulotomy) is a treatment that works well for many children. It may be done with a sharp instrument or a laser. A healthcare provider can often do this procedure in the office. A cut is made in the frenulum, allowing the tongue to move normally. Your child might need to see a speech therapist or other specialist after a frenotomy. This can help them learn how to retrain the muscles of the tongue.
Another option is frenuloplasty. This also involves lengthening the front part of the tongue.
When to call the healthcare provider
Call your child’s healthcare provider or a breastfeeding specialist if your child is having trouble breastfeeding. If you believe your child is having problems making sounds, see your child’s healthcare provider or a speech pathologist.
