Green arrows indicate tooth decay. Blue arrows indicate abscess at root of tooth. The<unk>  at the root of the tooth can travel through bone and infect surrounding soft tissue.<unk> s are usually diagnosed on history and physical exam in the dental office or at a clinic visit with an otolaryngologist. Swelling within the oral cavity or cheeks, along with a history of progressively worsening tooth pain and fevers, is usually enough evidence to support the diagnosis of a<unk> . Depending on the severity of the<unk> , further tests may include x-rays and CT scans of the<unk>  to better characterize the location and extent of the<unk> . If the<unk>  is drained with a needle or scalpel, then a swab of the<unk>  is collected to identify the microbes present in the abscess and to determine their respective susceptibilities to antibiotics. Other lab tests may include a complete blood count with differential, serum electrolyte concentrations, and other routine assays for an<unk> s workup.
