Yes, I did bring my son to the ER for a tooth that was knocked out.

Do you know that if trauma is caused to the teeth that it could also affect their jaw, maybe even injure it??
Originally posted by KaginDDo you know that if you hit your head hard enough that you can get a concussion??

I'm assuming you do not have children based on your smug remark.
Blunt Force Trauma to the Brain
The brain can be damaged by trauma in two ways. When the head is struck by a hard object the cerebral cortex (gray matter) can become bruised. If the force of the blow is sufficient to cause a whiplash like circumstance then the injury can occur to the nerve cells (axonal injury) deep in the white matter of the brain. Injury of this type involves a variety of forces including the acceleration of the object and the acceleration force imparted to the brain by the object. Injury results from the direct contact between the object and the head and the greatest injury to the head occurs from the initial direct impact with the blunt object. The area of contact may be large (a baseball bat, 2x4) or small (hammer head, a paper weight) but the velocity of the impact will largely determine the extent and type of damage caused by the resulting blow.
The cranium, the complex structure of bones that encloses and protects the brain, is composed of three layers; the outer table (hard outer layer of bone), the inner table (inner layer of hard bone), and the diploe or spongy bone layer between the two.
When the blunt object comes into contact with the bones of the human skull several reactions are possible. A piece of bone may break loose from the skull and be forced into the cranium with concentric fractures forming around the break area. This bone fragment or plug as it is called often takes on the approximate shape of the object itself. Another reaction is where the object causes an inward bending of the skull resulting in crushing of the outer table and diploe with fractures radiating outwards. In this case the inner table is left untouched by the blow. A blow can also cause a situation where there is both inward and outward bending of the skull structures. In this case, the inner table as well as the outer table and diploe are all shattered. Radiating fractures spread outward from the impact site.
