Six years prior, the patient accidentally swallowed a denture during a meal and immediately visited a nearby doctor. However, because spontaneous excretion was expected, regular imaging testing was used to monitor it. After 4 years, although the denture was still in the small bowel, as there were no symptoms, the regular follow-up was terminated. Because the patient's anxiety increased, he visited our hospital 2 years later. Surgery was performed, as it was determined that there was no possibility of spontaneous excretion. The denture was palpated in the jejunum. The small intestine was incised, and the denture was removed. As far as we know, there are no guidelines prescribing a clear follow-up period for accidental denture ingestion. In addition, there are no guidelines specifying surgical indications in asymptomatic cases. Nonetheless, there have been reports of gastrointestinal perforations with dentures, and we consider that earlier preventive surgical intervention is better.
