No dogs have "locking jaws", that is a myth.
There are no dogs with jaws that actually lock. That is a myth. Some dogs such as Staffordshire & Pit Bull terriers do have extremely strong bites though and can be almost impossible to break, which is where the myth originated.
It is recommended to use cold compresses against your cheeks and jaws for the first 24 hours following surgery. This will minimize the amount of swelling you experience. After 24 hours, it is recommended to use warm compresses to dissipate whatever swelling does occur as quickly as possible. A heating pad would probably be acceptable, so long as you don't set the heat too high.
depending on how broken it is yes but there diet will have to be changed radicaly
Dogs use their teeth and strong jaws to defend themselves.

yes , the main power is in closing the jaws, the same is true of dogs. It is the holding of the animal still, to retain you grip that causes the problem.
An animal's jaws and nose is generally called a "muzzle", especially if it is projecting.
Technically, yes dogs can chew on steel bones. However, this is a very bad idea as it will damage their jaws and teeth badly.
