Description

Technical Field

[0001] The present invention relates to the technical field of whitening devices, and in particular to a teeth whitening device. Background Art

[0002] In our daily diet, we inevitably eat colored foods. Except for light-colored foods such as tofu and eggs, most other colorful and colorful foods are the cause of yellow teeth. There are many kinds of bacteria on the surface of teeth, and they secrete many sticky substances on the surface of teeth. The intake of tobacco (smoking or chewing tobacco), tea, coffee, cola, red wine, and colored foods, etc., will leave pigments on our teeth. These pigments are adsorbed on these sticky substances, gradually turning the surface of the teeth yellow or black. Over time, these substances will gradually penetrate from the surface of the teeth into the inside of the teeth, forming internal stains, which will slowly discolor the inside of the teeth. Such teeth are called exogenously stained teeth.

[0003] The traditional method of teeth whitening is teeth cleaning in a dental clinic, which mainly uses large ultrasonic cleaning equipment to remove plaque, tartar, and pigments on the surface of the teeth. It is irritating to the teeth, especially patients with periodontal disease may experience some sensitive symptoms. There are also other disadvantages, such as the time spent on the way to the dental clinic and the time spent on queuing for appointments, the tense atmosphere in the dental clinic, the equipment with a strong metallic feel and the sharp sound. In addition, many people are worried about hygiene issues. Although the clinic will perform regular disinfection and use disposable tools, there is still a risk of cross infection. Most of the simple tools currently used are manual polishing tools, such as replacing the molar head with a polishing pad for manual polishing, which has poor results, is not convenient to use, and has a weak experience.

[0004] Therefore, it is necessary to design a new whitening device that can automatically polish teeth with good whitening effect and strong user experience. Summary of the invention
