Item #: SCP-3720

Object Class: Safe

Special Containment Procedures: SCP-3720 is currently being contained in the Standard Containment Block at Area-42B-N. SCP-3720 is to be kept in a hazardous substance locker (currently locker #46) protected by a passcode available only to level 2 research personnel and higher.

Description: SCP-3720 is a biohazardous green liquid in a clear plastic-bottle labelled as Brilhante, a generic mouthwash brand. Currently, no such brand is known to exist apart from SCP-3720. The bottle containing SCP-3720 is labelled as containing 18floz (532.32ml), though only approximately 278ml remain in the bottle. Upon initial containment, only 528ml remained in the bottle. The bottle containing SCP-3720 has shown no anomalous properties.

When a subject uses at least 20ml of SCP-3720 for at least 1min as if it were standard mouthwash, a 12—24 hour period of strong dental hygiene promotion, termed post-use promotion, occurs immediately afterwards. During post-use promotion, subjects will become remedied of most forms of mild-to-moderate dental-health issues. Cavities are healed, tooth decay is reversed, and oral irritations (such as canker sores and blisters) are cleared. Further inspection of subjects’ mouths show whitening, strengthening, and general cleanliness of the teeth to be much stronger than that of standard mouthwashes. The enamel of the subject’s teeth will also be much stronger than it was before the subject used SCP-3720.

When a subject ingests at least 20ml of SCP-3720, it will take approximately 5—10mins for SCP-3720 to be digested into the subject’s body. If the subject used SCP-3720 for at least 1min, post-use promotion will occur as usual, but if not, no anomalous properties will occur for the following 5—10mins while awaiting digestion.

When a subject has successfully digested at least 20ml of SCP-3720, the subject will contract a disorder termed gastrodysplasia ossificans progressiva (GOP) identified as 3720-A. This disorder displays close similarities to fibrodysplasia ossificans progressiva (FOP), with the exception that 3720-A only affects the gastrointestinal system of the subject’s body, and no other organ-systems will be directly affected by it.

When a subject becomes afflicted with 3720-A, the disorder and its symptoms will manifest quicker and more aggressively than FOP. Most subjects will die within 48hrs of having ingested SCP-3720. Only one subject is known to have survived for longer than 48hrs (dying at approximately 55hrs).

Discovery: SCP-3720 first came to Foundation attention when a chemist known as Antonio █████ was detained in ███████, Chile for unlicensed distribution of the item. The purported properties of the item attracted the attention of an embedded agent in the area, who was then successful in obtaining the item from local law-enforcement officials. The chemist was taken into Foundation custody for interrogation. [REDACTED], immediately given class B amnestics and later released. A transcript of this interrogation can be found in Addendum-OsM-I001.
