Because the dental flosser relies on the high-speed flow of water to flush out the residue on the surface of the teeth and in the crevices, so there are certain requirements for the water pressure, the general water pressure should be in the range of 0.3MPa to 0.6MPa, the best is to be adjusted to adapt to the adaptive requirements of the different groups of people.
The food debris stuffed in the gap between the teeth, in addition to making people uncomfortable and itself with bacteria, the greater harm is that it provides nutrients to dental plaque. If you don't get rid of it in time, plaque can easily calcify and become "tartar" that accumulates at the root of the teeth, compressing and stimulating the periodontal environment and shrinking the periodontium. Therefore, the use of toothpaste or toothpick, dental floss to clean the gap between the teeth, in fact, is to block the plaque of a major source of nutrients.
Necessity of a dental floss rinse:
The uneven surface of the teeth will still be unclean, bacterial growth only a very thin layer of nutrient film can be, the residual harmful effects of the film of dirt also still partially exists, both devastatingly strong and can be drilled into the holes of the pressure of the water flow from the principle of the most ideal way to clean the oral cavity.
According to the U.S. agency study, the pressure of the water column can be rushed into the gingival sulcus rinse to the depth of 50-90%, the pressure of the water column can not only clean to a variety of crevices, holes and convex and concave Saki surface, and the effect can be achieved by the microscopic thorough cleaning rather than just a macro-rough clearance, in addition to the teeth of the dental rinse oral cavity cleaning features, the water flow of gums and the role of the massage.
