Abstract: A periodontal pocket cleaning device is provided which has a very excellent effect for the prevention of periodontal diseases, which is least liable to cause injury to the periodontal pocket, which can be used at any place without limiting the place of its use, which is able to obtain a stabilized atomized jet without being influenced by the height position of the handy probe, and which is available at a low cost. The periodontal cleaning device includes a handy probe provided with an air-jet ejection mechanism, an air pump for producing compressed air, and an air-feeding tube for feeding the compressed air from the air pump to the handy probe. The handy probe is provided with a liquid storage tank for storing liquid agent such as water or liquid chemicals therein. The jet-out pressure of the compressed air to be ejected from the nozzle of the handy probe is set in a range of from 0.05 to 0.08 kg/cm.sup.2. The jet-out quanity of the compressed air is set in a range of from 2 to 30 l/min.
