A dental abscess is a localized collection of pus associated with a tooth. The most common type of dental abscess is a periapical abscess, and the second most common is a periodontal abscess. In a periapical abscess, usually the origin is a bacterial infection that has accumulated in the soft, often dead, pulp of the tooth.
Generally, the abscess can be eradicated through surgical drainage alone; however this is sometimes inadequate. Therefore, systemic antibiotic treatment may be required, but only if there is evidence of spreading infection. [9] As the bacteria involved are known, antibiotic therapy selection can be specific, based on published susceptibilities. [9]
It is a type of dental abscess. A periodontal abscess occurs alongside a tooth, and is different from the more common [2] periapical abscess, which represents the spread of infection from a dead tooth (i.e. which has undergone pulpal necrosis). To reflect this, sometimes the term "lateral (periodontal) abscess" is used.
After stabilizing the patient's airway, extracting the infected tooth will typically promote adequate drainage and the infection will resolve shortly thereafter. If the infection involves multiple primary spaces or any of the secondary spaces previously mentioned, then incision and drainage with culture-guided antibiotics may be indicated.
Tooth #5, the upper right second premolar, after extraction. The two single-headed arrows point to the CEJ, which is the line separating the crown (in this case, heavily decayed) and the roots. The double headed arrow (bottom right) shows the extent of the abscess that surrounds the apex of the palatal root.
Periapical periodontitis may develop into a periapical abscess, where a collection of pus forms at the end of the root, the consequence of spread of infection from the tooth pulp (odontogenic infection), or into a periapical cyst, where an epithelial lined, fluid-filled structure forms.
It is understood about 30-40% of cases of the rare infection infective endocarditis are caused by bacteria in the mouth. High-risk patients dying after not getting antibiotics at dentist ...
A periodontal abscess can occur as the result of tooth fracture, food packing into a periodontal pocket (with poorly shaped fillings), calculus build-up, and lowered immune responses (such as in diabetes). Periodontal abscess can also occur after periodontal scaling, which causes the gums to tighten around the teeth and trap debris in the pocket.
