Frenulum

Say: FREN-yuh-lum

The frenulum is the piece of skin that attaches your tongue to the bottom of your mouth. But if your frenulum is too short, that's called tongue-tied, and it can cause problems with your speech. Doctors sometimes do an operation to free up the tongue by snipping the frenulum. If you need this operation, a doctor will give you a special medicine called anesthesia to keep you comfortable.
