Background
With the rapid development of economy and the continuous progress of society in China, the awareness and attention degree of people on oral health care is continuously increased, and the oral cleaning product is also in a rapid development stage and is relatively fast to improve. For example, in the process of orthodontic treatment, due to the blockage of orthodontic appliances such as brackets, arch wires and the like, the adjacent surfaces of teeth and the vicinity of the brackets are difficult to clean, so that food residues are embedded and plaque is accumulated, and caries is caused. Furthermore, for periodontal patients, oral hygiene and hygiene are important, and the retention of bacterial plaque directly affects the periodontal condition: on the other hand, china is already in the early stages of aging society. If the old people have misaligned teeth, have not placed tooth sockets, or suffer from periodontal disease, degenerative disease causing gingival atrophy and exposing tooth roots, obvious gaps are formed among teeth. It not only can be embedded with food, but also the brush head or dental floss of the common toothbrush can not fully enter the teeth gap for cleaning, so that the adjacent teeth of the crowd have high caries and are repeatedly discomforted and abraded for a long time. The cleaning effect of the tooth space is worthy of being confirmed for the larger tooth space, the tooth root exposer caused by gingival atrophy, or the orthodontic appliance, the fixed restoration, the implanted tooth, the lacuna retainer and the periodontal splint in the mouth.
The interdental brush provided on the market at present has various selections of I, V, J and L according to the appearance shape; the toothbrush can be divided into SSS, SS, S, M, L and LL according to the types of the toothbrush heads so as to be suitable for cleaning the tooth spaces with different sizes.
The interdental brush has several advantages: 1. the interdental brush can remove food residues like toothpicks, and the brush head of the interdental brush is soft and hardly causes mechanical damage to gums. 2.
