1. A dental treatment apparatus that energizes a dental treatment site with a high-frequency current, the dental treatment apparatus comprising:
a holder configured to hold an electrode placed at the dental treatment site;
a power supply configured to energize the electrode with the high-frequency current; and
controller circuitry configured to:
cause, during energization operation, the power supply to provide a stop period where energization of the electrode with the high-frequency current is stopped between a single energization period and a next single energization period, and
cause the power supply to provide a plurality of continuous energization periods in the single energization period and to interpose a pause period where the energization of the electrode with the high-frequency current is paused between two adjacent continuous energization periods,
wherein the pause period is shorter than the continuous energization period, and the stop period is more than twice the continuous energization period.
