Jason SR Print(0) ID 1181040605 T1 Gingival Abscess (Periodontal Abscess) T2 The Atlas of Emergency Medicine, 5e YR 2021 FD 2021 PB McGraw-Hill PP New York, NY SN 9781260134940 LK accessemergencymedicine.mhmedical.com/content.aspx?aid=1181040605 RD 2024/10/10 AB Gingival abscesses tend to involve the marginal gingiva and result from entrapment of food and plaque debris and subsequent staphylococcal, streptococcal, anaerobic, or mixed bacterial overgrowth. Localized swelling, erythema, tenderness, and fluctuance in the space between the tooth and gingiva ensue. There may be spontaneous purulent drainage from the gingival margin, or an area of abscess pointing. When the gingival abscess involves the deeper supporting periodontal structures, referred to as a periodontal abscess, the patient may present with a fluctuant vestibular abscess or with a draining sinus that opens onto the gingival surface.
