With the improvement of living conditions, people pay more and more attention to oral health and oral beauty.

Oral cleaning is currently the most dominant way to maintain oral health, and includes toothbrushes, flossing, and tooth-rinsing devices. Besides oral health, people begin to pay more attention to oral beauty at the same time, and oral beauty is also more and more important. At present, the oral cavity is mainly orthodontics, whitening patches, tooth washing, cold light whitening and the like. With the increasing demands of people for oral health and oral beauty, various oral cleaning and oral beauty tools have been developed.
