Description

The present invention takes up the field of tooth cleaning technology, and specifically is a tooth cleaning device.

With the progress of society and the improvement of living standards, oral hygiene is becoming more important and tooth brushing becomes a daily routine, but conventional tooth brushing is time consuming and inefficient. Conventional toothbrushes are less than 3 cm in length, require brushing the tooth surface one by one, and brush each part at least 10 times, which requires a considerable amount of time to clean the teeth. When brushing teeth with a conventional toothbrush, it is not possible to brush the teeth thoroughly or cleanly for personal reasons, which can cause tooth decay and periodontal disease over a long period of time. It can lead to damage, and children often have tooth decay if they don't brush their teeth properly. In addition, since conventional tooth brushing must be done by hand, it is difficult for people with disabilities to brush their teeth.
