SCP-323 "sheds" teeth on a regular basis, assumedly during silences between chants while unobserved. All teeth shed by SCP-323 should be removed from the containment room promptly at the beginning of the next round of chant. Teeth should be sealed in epoxy before removal and sent to Laboratory NCan-05 for further study.
SCP-323 is capable of manipulating metallic objects, especially iron. Metal items that catch SCP-323's attention are invariably launched into the chest of the nearest handler with impressive force. SCP-323 does not attack with the intent to kill, instead deliberately avoiding piercing or any vital organs, excepting the heart.
Those wounded by SCP-323 are overcome with the urge to push shed teeth into the wound. Upon doing this, the affected's body undergoes rapid mutation, always involving a violent rupture of the cranium and typically including explosive hair growth, the bursting of the spine out from the tail bone, tooth growth, the bursting of the finger bone from the fingertips, ultimately the rupture of the skin and death from loss of blood. During this process the affected becomes violent and will attempt to place SCP-323 upon their exposed brain stem and escape. Affected personnel must not be allowed to do this, and in the event of injury the room is to be flooded with cyanide gas immediately.
Regardless of incident, all Class D personnel in contact with teeth must ingest 75mg of silver oxide immediately upon leaving the containment room.
