Tongue-tie in children is one of the lesser-known birth defects that can limit the normal movement of the tongue and the child's pronunciation.

Tongue-tie is a mild congenital defect caused by a short, thick, or tightly fused frenulum that impedes normal tongue movement. In most cases of mild tongue-tie, the tip of the tongue will gradually separate on its own. In others, frenulum surgery may be indicated, which is a quick, minor procedure and the child can breastfeed and eat immediately afterwards.

Tongue-tie or short frenulum is a congenital defect of the baby's tongue. This is a mild defect and can be treated by cutting the baby's frenulum.
