The oral care device includes a fluid pump 46, a liquid source 50, and a gas source 12, the pump being in operative communication with the liquid source and the gas source, In a selected sequence, the oral care device further generates a series of gas jet fluid pulses and / or jet-type fluid flows using a liquid slug that is directed toward the nozzle and directed from the nozzle to the teeth. A control assembly for selecting a pulse flow or slug flow directed to the nozzle assembly 80 and directed from the assembly to the teeth with a specific set time and sequence, the pulses being 0.001-0. A pulse width in the range of 5 seconds, a pulse height in the range of 0.1 to 10 Newton, a rise / fall time in the range of 0.5 to 250 ms, and a range of 2 Hz to 20 Hz. With a repetition rate and a gas / liquid mixture ratio of gas volume to liquid volume in the range of 40 to 95%, and the fluid slug in the jet stream is 0.05 to 0.5 ml per hole. Having a volume in the range, a diameter in the range of 0.1 to 2 mm, and a repetition rate in the range of 2 Hz to 20 Hz.口腔ケア機器は、流体ポンプ４６と、液体の供給源５０と、気体の供給源１２と、を有し、該ポンプは、該液体の供給源及び該気体の供給源に動作可能に連通し、選択されたシーケンスで、ノズルに向けられ該ノズルから歯へと向けられる、液体のスラグを用いた一連の気体噴射流体パルス及び／又はジェット型の流体の流れを生成し、該口腔ケア機器は更に、ノズルアセンブリ８０に向けられ該アセンブリから歯へと向けられる、特定の設定時間及びシーケンスを持つパルス流又はスラグ流を選択するための制御アセンブリを有し、該パルスは、０．００１乃至０．５秒の範囲内のパルス幅と、０．１乃至１０ニュートンの範囲内のパルス高さと、０．５乃至２５０ｍｓの範囲内の立ち上がり／立ち下がり時間と、２Ｈｚ乃至２０Ｈｚの範囲内の反復率と、４０乃至９５％の範囲内の気体容積対液体容積の気体／液体混合比と、を持ち、該ジェット流にける流体スラグは、穴毎に０．０５乃至０．５ｍｌの範囲内の体積と、０．１乃至２ｍｍの範囲内の直径と、２Ｈｚ乃至２０Ｈｚの範囲内の反復率と、を持つ。
