Pediatric dentists frequently encounter pericoronitis of the first molar, most of which resolve spontaneously. We describe the case of a 7-year-old girl who was referred to our hospital with intractable swelling in the right buccal region. Case Presentation: Intraoral examination showed an erupting right mandibular first molar and facial examination revealed swelling and an accumulation of pus in the cheek region. Radiographic examination revealed no pathological findings; therefore, it was diagnosed as a cheek abscess, and the region was incised that day. However, the symptoms recurred 3 weeks later, and cone-beam computed tomography detected a bone defect in the right mandibular first molar region, confirming a diagnosis of dentoalveolar abscess caused by pericoronitis of the first molar. The swelling resolved after incision of the abscess, and bone recovery was confirmed by X-ray in the follow-up period. Conclusions: Erupting first molars is at risk of pericoronitis, which may sometimes progress to a dentoalveolar abscess. Dental professionals should be alert to this possibility and should advise pediatric patients and their guardians to maintain good oral hygiene around erupting molars.<\/jats:p>","DOI":"10.3390\/diagnostics15121531","type":"journal-article","created":{"date-parts":[[2025,6,16]],"date-time":"2025-06-16T09:51:22Z","timestamp":1750067482000},"page":"1531","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Dentoalveolar Abscess Caused by Pericoronitis of an Erupting First Molar"],"prefix":"10.3390","volume":"15","author":[{"given":"Kana","family":"Kawashima","sequence":"first","affiliation":[{"name":"Department of Pediatric Dentistry, Graduate School of Biomedical and Health Sciences, Hiroshima University, Hiroshima 734-8553, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masashi","family":"Ogawa","sequence":"additional","affiliation":[{"name":"Department of Pediatric Dentistry, Graduate School of Biomedical and Health Sciences, Hiroshima University, Hiroshima 734-8553, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Meiko","family":"Tachikake","sequence":"additional","affiliation":[{"name":"Department of Pediatric Dentistry, Graduate School of Biomedical and Health Sciences, Hiroshima University, Hiroshima 734-8553, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuto","family":"Shoji","sequence":"additional","affiliation":[{"name":"Department of Pediatric Dentistry, Graduate School of Biomedical and Health Sciences, Hiroshima University, Hiroshima 734-8553, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tatsuya","family":"Akitomo","sequence":"additional","affiliation":[{"name":"Department of Pediatric Dentistry, Graduate School of Biomedical and Health Sciences, Hiroshima University, Hiroshima 734-8553, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ryota","family":"Nomura","sequence":"additional","affiliation":[{"name":"Department of Pediatric Dentistry, Graduate School of Biomedical and Health Sciences, Hiroshima University, Hiroshima 734-8553, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,6,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Sobkowska, \u0141., Sobkowska, J., Dudek, D., Grabarek, B.O., Czajka-Jakubowska, A., and Przysta\u0144ska, A.
