What characterizes a tooth abscess?

A tooth abscess is specifically characterized by the presence of a pus-filled sac at the root of the tooth, which is the result of a bacterial infection. This infection typically occurs when bacteria invade the pulp of the tooth, often due to tooth decay, injury, or dental procedures that expose the pulp to bacteria. The accumulation of pus indicates the body’s immune response to the infection, and this is what leads to the formation of the abscess.

In contrast, while gaps in teeth, swollen tonsils, and discolored enamel may be associated with various dental or health issues, they do not define a tooth abscess. Gaps in teeth can arise from tooth loss or spacing issues, swollen tonsils are linked to infections in the throat, and discolored enamel may signify enamel erosion or staining, none of which pertain to the specific condition of an abscess. Therefore, the defining feature of a tooth abscess is indeed the pus-filled sac at the tooth root.
