A newborn who is having trouble nursing may have a common condition known as ‘tongue-tie’ or ankyloglossia. This condition is caused when a frenum – a small piece of tissue – connects the bottom of the tongue to the bottom of the mouth and restricts normal movement such as nursing or speaking.
We typically have three frenums in our mouth. You might be able to feel the frenum that connects the top of your inner lip to the top of your mouth, or the frenum that connects the bottom of your lower lip to the bottom of your mouth. The third frenum connects the underside of your tongue to the bottom of your mouth, and is often the problem with children who cannot nurse.
