A plain film examination needs to be completed to clarify the location of the denture if it is swallowed in the stomach. If they are in the esophagus or in the stomach cavity, emergency gastroscopy should generally be considered for emergency foreign body removal. The size of the denture and whether it can pass through the esophagus need to be clarified before removal to prevent scratching of the esophageal and gastric mucosa, which can easily lead to gastrointestinal hemorrhage. If the denture is relatively large, the possibility of esophageal scratching is higher and surgical treatment is needed to give foreign body removal. If the denture has already entered the small intestine, there is no way to remove it by gastroscopy in this case, and it needs to be further removed by active surgical laparoscopic or surgical open surgery treatment. Dentures in the gastrointestinal tract can easily lead to damage to the gastrointestinal mucosa, causing delayed bleeding or perforation.
