Definitions

  • the present invention relates, in general, to a oral irrigator having a low-temperature plasma generating device and, more particularly, to an oral irrigator, which realizes a function of sterilizing washing water, which is externally sprayed to clean teeth, using low-temperature plasma.
  • tooth diseases, gum diseases and the like occur when cleaning of teeth is neglected after the intake of food. Accordingly, cleaning teeth within a predetermined period after eating food teeth is one of the most important and basic factors in maintaining healthy teeth and gums. In order to clean teeth and to maintain clean teeth, toothbrushes, toothpicks, dental floss and the like are used.
  • Such a toothbrush may be easily used to remove foreign materials that are attached to the outer surfaces of teeth, but is disadvantage in that it cannot completely remove foreign materials that are tightly caught between the teeth, and in that all the surfaces of the teeth cannot be uniformly brushed.
  • Such a toothpick may remove foreign material caught between teeth, but is disadvantage in that it is impossible to clean the overall surfaces of teeth, and in that it may cause gum diseases by deforming a set of teeth or damaging gums.
  • the dental floss is known to dentist as the best method of cleaning teeth but the manipulation thereof is considered by unskilled users to be complicated, and thus only a very small number of users use it.
