Classification and external resources

Dental subluxation is a traumatic injury in which the tooth has increased mobility (i.e., is loosened) but has not been displaced from its original site in the jawbone.


This is quite a common condition and one of the most common traumatic dental disorders.[1] It is most commonly seen in school children. However, the exact prevalence is difficult to be assessed because dental subluxations are often asymptomatic or only mildly symptomatic, and even overlooked by caregivers when treating more serious dental traumas in adjacent teeth.


Dental subluxation is not an urgent condition, and is unlikely to result in significant morbidity if not seen within 24 hours by a dentist.[2] However, a follow-up period of at least one year is recommended [3] because of the increased incidence of the necrosis of the tooth pulp , which occurs in 25% of the cases [4], in this case, the tooth may appear dark in color compared to it's lateral teeth due to the rupture in the micro blood vessels, and bleeding in the internal tissues following the trauma.[5]

It is usually conservatively treated by good oral hygiene with 0.12% chlorhexidine gluconate mouthwash, a soft and cold diet, and avoidance of smoking for several days.[2] When the injured teeth are painful, especially during function, a temporary splinting of the injured teeth may relieve the pain and enhance eating ability.[6]
