As for the dentist, he is relatively blunt when it comes down to talking to a child about their health, is completely professional, and has two to three assistants with him during an operation.

==Chronology==
===Shinyaku Toaru Majutsu no Index===
====Ichihanaran Festival Arc====
The establishment was first shown when Fremea Seivelun was getting surgery for her tooth after continuously drinking too much hot chocolate every night before going to bed despite Hamazura Shiage and Takitsubo Rikou's warnings.
Kinuhata Saiai later accompanied a powerless Kuroyoru Umidori into the establishment after Shiage noticed that she somehow stopped chewing with her back teeth. Due to Shiage sticking gum into the ports of her cybernetic arm, she was rendered powerless as she could not create nitrogen spears. As such, Umidori was at the mercy of Saiai, who forced her into the clinic.
