Description

a dental washing machine

technical field

The invention belongs to the field of toothwashing machines, in particular to a toothwashing machine.

Background technique

Plaque is the culprit of periodontal disease, and it will continue to re-form on the tooth surface after being removed. Inadequate plaque removal, coupled with the gradual deposition of mineral salts in saliva, will form tartar over time. The presence of calculus makes the plaque in close contact with the tissue surface, causing an inflammatory response in the periodontal tissue. In addition, the porous structure of tartar can easily absorb a large amount of bacterial toxins, and calculus can also hinder tooth brushing. If it is not cleaned for a long time, it may cause gingivitis, periodontitis, bleeding gums, bad breath, and eventually cause teeth to loosen and even fall off. Therefore, the cleaning of teeth is very important.

Teeth cleaning is a good means of dental health care, and it is also the primary measure to treat periodontal disease. Regular tooth cleaning can not only completely remove plaque and calculus on teeth, but also keep periodontal tissue healthy and prevent periodontal disease. Moreover, it is easy to find small and imperceptible dental diseases when cleaning teeth, such as relatively hidden dental caries, so as to achieve the purpose of early detection and early treatment.

Toothbrush is a tool for cleaning teeth commonly used by modern people. The purpose of cleaning teeth is achieved by moving teeth with a toothbrush. However, there are often users who are too tired to brush their teeth manually, and they are often perfunctory when brushing their teeth, resulting in the growth of bacteria. Therefore it is very important to find a tool that can replace the toothbrush for cleaning teeth.
