Claim:
1. A handheld irrigator, consisting of: an enema-shaped body consisting of a pear-shaped bulb with elastic walls with a tapered tip attached to the bulb; the pear-shaped bulb being configured to be partially filled with a liquid; a tubular element placed inside the body; the tubular element having a first end being sealingly fixed to an internal surface of the tip at a narrowest part of the tip; a second end of the tubular element being installed with a gap between the second end and a bulb bottom, the tubular element having an orifice in a portion of the tubular element located in the tapered tip; a cross-sectional area of the orifice being 0.05 to 0.6 times a cross-sectional area of a lumen of the tubular element; the irrigator producing a gas-liquid flow while squeezing the bulb with a hand; the gas-liquid flow being a jet with a force sufficient to remove unwanted objects between teeth; the jet force being determined by a ratio between the cross-sectional area of the orifice and the cross-sectional area of the lumen of the tubular element.
