A dental and oral fetish documentary depicting cavity treatment using the latest medical technology and equipment. 20-year-old Kaede has been struggling with bad breath, which is ultimately diagnosed as decay in her wisdom tooth. After much distress over her persistent odor, she decides to undergo extraction. However, Kaede has a rare body type resistant to anesthesia—despite multiple injections, the numbing effect remains insufficient, causing her visible pain and facial grimacing throughout the procedure. The film meticulously documents the entire process, including four rounds of anesthesia administration, until the tooth is finally extracted.
