Predatory dental quadruped, one hundred multi-continental sightings post-1886. Precise details unknown: eyewitnesses invariably succumb to its effects—primarily, the rapid overproduction of teeth, inhibiting their ability to verbalize intelligibly. Recording devices are instantaneously compromised via the manifestation of dentin in critical components. Artistic representation varies wildly, yet focuses exclusively on various amalgamations of teeth and the associated gingiva.

SCP-4910 seems to be capable of differentiating between those unaware of its properties—typically civilians—whom it uses for sustenance; and those who specifically seek to either capture or harm it—such as personnel of both mundane and occult organisations—whom it targets for the purposes of esophageal replication.

While similar in most respects to standard victims, those targeted for replication act as a vector for SCP-4910's anomalous properties.

Previous 58 capture attempts unsuccessful, involving serious dental violence, internal bleeding, loss of life. Thirteen MTF-ε agents missing in action. Seven had [DATA EXPUNGED] plaque; since euthanised. Transformative autocannibalisation claimed five.
