The dental emergency dental trauma are the most common in children and adolescents and the teeth most often affected are the upper incisors.
In case of trauma of a permanent tooth consequences ranging from extortion , or the injury of the supporting tissues of the tooth , to the dislocation , ie the partial displacement of the tooth from its seat , until avulsion in which has the total expulsion of the tooth from its socket . In other cases, the tooth fracture can be more or less serious if it involves only the hard tissues of the tooth ( enamel and dentin ) , or if it also affects the pulp (the " nerve "); in the worst cases the fracture involving the root of the tooth and its recovery is difficult if not impossible. In any case you need to go to the dentist as soon as possible : the more timely intervention is the better the prognosis. If it is concussion may happen that the tooth , although intact, lose its vitality, or goes into necrosis , in which case it must be devitalized ; otherwise they will be made periodic inspections.

In Dislocation the loss of viability is much more likely and, in some cases, the dentist will assess the need to reposition the tooth with the orthodontic appliance.
If the trauma causes avulsion of the tooth is vital keep it in a container with saline solution (if it is not available is fine milk or saliva) and immediately go to the dentist who will perform the REPLANTING tooth, repositioning it in the socket and "blocking" the teeth adjacent to what that week. When storing the tooth expelled must be careful not to touch the root.The success of replanting is closely related to the timeliness of the intervention: it takes a few hours because it is no longer possible to "take" of the tooth in its socket.
The viability of the replanted tooth is almost always compromised.

If you need to retrieve the Fracture of the tooth fragment that must be stored in milk or saliva. If the fragment is intact the dentist will provide to its bonding , otherwise perform the reconstruction composite. If the fracture involves the pulp in most cases be necessary to revitalize the element . Otherwise it will be periodically assessed its viability.

In the trauma of the deciduous teeth the dentist based on the maturity of the corresponding permanent teeth will consider whether to intervene , devitalizzando or by extracting the affected tooth , or wait and check again.
The total avulsion of deciduous generally do not involve major problems, while dislocations intrusive , in which the tooth falls within its cavity , can cause permanent damage to the tooth corresponding . The consequences can be assessed only in eruption .

In all cases you will need to check the patient periodically.
