Tongue-tie is when the tongue cannot move normally because it is attached to the floor of the mouth. This causes problems eating and speaking. Tongue-tie is present at birth.
A tissue called the frenulum helps the mouth to develop before and shortly after birth. The frenulum is attached to the underside of the tongue. After birth, the frenulum should start to shrink and loosen its hold on the tongue.
In some babies, the frenulum does not shrink as it should. The cause is not known. Genetics may play a role.
This problem is more common in boys. It may also be more common in children who have other family members who have had it.
Symptoms vary from child to child. Some will not have symptoms. Those who do may have problems with latching onto the nipple during breastfeeding.
