I just had an initial consultation at a TMJ specialist clinic at the University of Minnesota. During my evaluation, the specialist told me that 40-50 mm is how wide the average person (and "normal" jaw) can open. I, like other people with hypermobile joints, can open my mouth comfortably, without strain, to a solid 55 mm.
They open it very wide.
A mouth prop is a safety device used by dentists to keep the mouth wide open when they perform a procedure. It is also sometimes known as a bit block.
You can't. You can only open your mouth as wide as your jaw will let you.
Open the mouth wide.
Birds
roughly 65 degrees
Wide open. A gaping hole is a wide open hole. A gaping mouth is one which is hanging open, usually from astonishment.
Just as I opened my eyes, the shark's mouth gaped open right in front of me. The gate suddenly swung as wide as a mouth gaped open.
Very wide. Approximately 69m.
hippos can open there about 3 feet or more depending on the size
