Abstract: A toothbrush for providing germicidal UV-C radiation to a users mouth. The tooth brush has a main body portion arranged along a longitudinally aligned axis. The main body portion includes a power source, a controller board, a power switch mechanism; and is interoperability attached to a longitudinally aligned neck/head portion. The longitudinally aligned neck/head portion has a replaceable/detachable brush head and a medial neck portion. The neck/head portion further includes a neck cavity for operably receiving a germicidal UV-C lamp. The germicidal UV-C lamp is arranged along a longitudinally aligned axis to provide ultraviolet radiation in 360° radiating illumination about the longitudinally aligned axis. The germicidal UV-C lamp provides ultraviolet radiation between the range of about just less than 100 nm to about just greater than 280 nm. The replaceable/detachable brush head includes a transparent base and a plurality of vertically aligned bristles.
