A therapeutic micro-current delivery device includes a first electrode in electrical contact with a user at a first user location, a second electrode in electrical contact with the user at a second user location, a power source operable to provide a first voltage potential at the first electrode and a second voltage potential at the second electrode, and a micro-current control circuit in electrical communication with the first electrode, second electrode and power source. Electrical contact of the first electrode at the first user location and electrical contact of the second electrode at the second user location completes an electrical circuit. The micro-current control circuit generates a micro-current Iramped through a user between the first location and the second location that increases from a start current Istart to an end current Iend over a rise time trise. Oral care devices and micro-current control methods are also disclosed.
