How can odontogenic infections propagate through the body?

Odontogenic infections can propagate through the body primarily through the venous system, which is particularly significant given the close anatomical relationships in the head and neck region. Infections arising from dental sources can enter the venous system, potentially leading to serious complications such as cavernous sinus thrombosis or spread of infection to the brain. The venous drainage of the teeth and oral cavity is closely interconnected with the dural venous sinuses, making the risk of intracranial complications a critical concern in the management of odontogenic infections.

While infections can also spread via other pathways, such as the lymphatic system or by direct extension to surrounding tissues, the venous route poses a greater risk of systemic and central nervous system involvement. Understanding these pathways is essential for dental health professionals in terms of diagnosis, treatment planning, and managing potential complications associated with odontogenic infections.
