We describe the case of a 1-year 3-month-old female with a foreign body in the oral cavity. She was referred to our hospital with chief complaints of suspected supernumerary teeth and blisters, and the initial examination revealed blister-like swelling and a white swelling on the hard palate. Intraoral photographs were obtained and examined from multiple angles, revealing findings that resembled a character. Careful re-examination showed that a three-dimensional sticker was attached to the hard palate, which could be removed in one piece. It is important for dental professionals to conduct intraoral examinations of pediatric patients with the understanding that unexpected findings may be present, and think about a foreign body in palatal lesions. In addition, this report highlights a new risk for caregivers supervising infants, as seemingly harmless stickers can remain in the mouth for extended periods.<\/jats:p>","DOI":"10.3390\/diagnostics16030493","type":"journal-article","created":{"date-parts":[[2026,2,5]],"date-time":"2026-02-05T16:30:47Z","timestamp":1770309047000},"page":"493","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Palatal Mucosal Inflammation Caused by an Unusual Foreign Body in an Infant"],"prefix":"10.3390","volume":"16","author":[{"given":"Shunya","family":"Ikeda","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"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9387-7746","authenticated-orcid":false,"given":"Yuko","family":"Iwamoto","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":"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":"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":[[2026,2,5]]},"reference":[{"key":"ref_1","first-page":"639","article-title":"A case of a Drinking-strew-like Foreign Body lmpacted around a Teeth","volume":"45","author":"Mizutani","year":"2007","journal-title":"Jpn.
