Some people let abscessed teeth get so bad that they end up in the hospital and their condition can be life threatening. A report published in the Journal of the American Dental Association (Sept. 2010) reviewed hospital admission data from 2007 and concluded the average cost of care per patient was $13,590. The average stay in the hospital was about 3 days. The total hospital charges in 2007, for dental abscess admissions, were $105.8 million (23,001 hospital days). The average cost of examining and removing an abscessed tooth in a dental office is $232, as an outpatient procedure.
