An apparatus for performing dental hygiene includes a mechanism to sterilize a head portion based on an ozone generator integrated with a base of the apparatus. The ozone generator includes a corona discharge tube, a micro air pump to circulate air through the corona discharge tube, and a bubble diffuser to diffuse ozone in a fluid. The ozone diffused fluid is transferred to a space around the head portion to sterilize the head portion. The space around the head portion is created by a cap like device connected to the head portion in watertight manner. An ultrasonic mechanism is coupled to the cap like device as an additional sterilizing mechanism, and generates ultrasonic waves through the fluid held around the head portion for sterilizing the head portion.
