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.
He stood there with his mouth gaped open, utterly shocked by what he had just heard.
Very wide. Approximately 69m.
hippos can open there about 3 feet or more depending on the size
I was wondering how wide can a Wolf open its mouth lol .And I tried to search it on the Internet but couldn't find it anywhere. I would really like if I could get some help . Thanks.
