- ―Juan's only line
When Juan is being scanned to cross the marigold bridge and he is accepted by the Departures Agent, he kindly gives her a complement after she found out that his photo is placed on the dentist's ofrenda.
Role in the film
Juan briefly appears during the scene where Miguel Rivera and Dante arrive at the Land of the Dead's departure area where the Departures Agent scans him to know if his photo is on his ofrenda before passing. Being scanned successfully due to his photo placed on the dentist's ofrenda, Juan is accepted and allowed to cross the bridge before sunrise to which Juan thanks her for allowing him to cross. Juan then leaves, followed by Héctor Rivera disguised as Frida Kahlo passing through. He is not seen again afterwards.
- Juan Ortodoncia is one of John Ratzenberger's least recognizable roles, due to him saying only one line. Therefore, he has the shortest line of all the roles Ratzenberger has played, with only one word of dialogue, making it one of Ratzenberger's smallest role in a Pixar film to date.
- His last name means "orthodontics" in Spanish.
