mouth opening

Lips parting wide

The act of parting the lips, whether to speak, eat, breathe, or express emotion.

In medical and dental contexts, mouth opening refers specifically to the range of jaw motion—how wide a patient can open their mouth: Limited mouth opening can indicate TMJ disorder.

The phrase also describes the physical aperture itself: The mouth opening was too small for the endoscope.
