Fractured tooth: it varies depending on the degree of fracture and twinge to that area. In cases of severe fractures, emergent medical care is adviced.

When teeth and their supporting structures are
subjected to impact trauma, the resultant injury
manifests either as a separation or a crushing injury or
a combination of both (1) (Fig. 1).
Separation injuries are exemplified by displacement
of teeth during which there is cleavage of tissues such as
the periodontial ligament (PDL). This occurs during
avulsions and extrusive luxations. Damage to cells in
the involved tissues is minimal, so rapid healing is
favored following appropriate treatment.
Crushing injuries cause more damage due to the
destruction of both tissue cells and intercellular
components. This type of injury is exemplified by
displacement of teeth against adjacent alveolar bone,
the worst of which is intrusive luxation.
During a crushing traumatic event, the cells and
associated tissues are damaged and must be removed (by
macrophages and osteoclasts) in order to initiate repair.
Thus the healing process cannot be expected to proceed
as quickly as that observed for separation injuries.
Understanding the difference between separation an
