An ozone generator voltage verification light assembly generates a visual or audible indicator, such as a neon light, to verify that an ozone generator is generating the proper voltage to generate ozone, and/or ozone generator voltage verification light assembly testing assembly operatively connects to an ozone generator, and visually indicates if an irregularity in voltage occurs. The ozone generator includes a power source for supplying electrical current, and a transformer that generates high voltage. The ozone generator also includes single or multiple ceramic plates disposed in a spaced-apart, parallel relationship, and coated with stainless steel mesh. Voltage generated by the transformer contacts the ceramic plates by means of an electrode. Accordingly, ozone is generated by discharging electricity through electrodes that contact in both sides of ceramic plate.

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.
