For things in your head that are designed to eat stuff, eating stuff seems to be kind of a big deal for teeth.

Ingesting electronics tends to be a bad idea. They don't taste good (except for Android phones) and they can cause issues, uh, later on. Or so I hear. From a friend. These pills, on the other hand, are specifically designed to be eaten, and they operate from inside your body, transmitting medical data straight to your phone.
