hello and welcome,
if the pain is on the site of tooth extraction,it may be due to postoperative osteitis called dry socket
.it is basically a focal osteomyelitis
in which the blood clot has disintegrated or been lost,with the production of a foul odour and severe pain
of the throbbing type,but no suppuration.
the pain starts by 2nd or 3rd post-operative day and lasts for 7-10 days and is extremely painful.anaerobic micro-organisms also play a significant role in the development of this condition.
sometimes the dry socket may be associated with low-grade fever
and ipsilateral lymphadenopathy
the exposed bone is necrotic,and sequestration of fragments is common.
tte aim of treatment is to keep the extracted socket clean and protect the exposed bone.
the socket is irrigated with mild warm antiseptic and then filled with obtundant dressing using zinc-oxide eugenol and iodoform gauze.the dressing is changed everyday.
probably the most important single factor in prevention of extraction complication is gentleness in handling living tissues.
