Tooth Abscess: Types, Causes, Complications

9. Why Are Abscesses So Serious?

Abscesses should be treated right away by a dentist because they can lead to life-threatening complications. The bacteria can spread via the bloodstream into the bones, causing osteomyelitis, which may require oral or intravenous antibiotics. Typically, the bone affected is the one closest to the infection, but the infection can travel. The abscess can also cause cavernous sinus thrombosis, a blood clot in the sinuses, near the brain. Ludwig's angina is another possible complication. In this case, the abscess develops on the floor of the mouth and may swell until it blocks breathing.
