Inside mouth describes images depicting the inside of a character's mouth from a perspective that implies the viewer is on the tongue of a character, either looking out past the teeth, or down into the character's throat. Often times, these images include a character inside of the mouth. This tag is heavily associated with Vore.
While similar, mouth shot implies a character showing off their mouth to the viewer with the character's face or body partially or fully visible.
