Methods, apparatuses, systems, and computer-readable media for communicating via an electronic device for use in a mouth environment of an animal and resistant to damage from bodily fluids and pressure. The device can be anchored to a tooth or a teeth of the mandible, or implanted in (or attached to an implant in) the maxilla or mandible. The device includes: a power device, which can power the apparatus, a memory storage device, which can store and recall data; a communications subsystem, which communicates with one or more remote devices; an output device, which creates stimulus directly or indirectly observable in the mouth environment; an input device, which can create signals according to activity in the mouth environment and can send them to the memory storage device and/or processor; and a processor coupled to the memory storage device, the communication subsystem, the output device and the input device.
