A pneumatic dental care device for private use which by means of a combination of air, liquid and powder at high pressure cleans the user's teeth and removes plaque and discoloration. The device consists of a base unit (100) and a hand unit (300) which are connected via a flexible, sheathed tube and wire bundle (200). The base unit contains a microcompressor (120), a liquid container (130) and a powder container (140). Liquid and/or powder are discharged at high pressure through an exchangeable nozzle unit (400) on the hand unit. The nozzle unit consists of one or more flexible (bendable) jet stems (401). The microprocessor, the powder container and the liquid container can be replaced by an exchangeable compressed air tank and/or pressurized liquid and/or powder containers in different configurations. The components of the device can also be integrated into a hand-held unit.
