Background

In daily diet, people inevitably eat colored foods. Except light foods such as bean curd and eggs, most colorful gourmets are all the cause of yellow teeth. There are a variety of bacteria present on the tooth surface that secrete a number of viscous substances on the tooth surface. Tobacco (smoking or chewing tobacco), tea, coffee, cola, red wine, and colored foods, etc., all leave color on our teeth. These pigments adsorb on these viscous substances, gradually turning the tooth surface yellow or black. Over time, these substances can also gradually penetrate into the teeth from the surface of the teeth to form internal stains, so that the interior of the teeth slowly discolors, and the teeth are changed into exogenously stained teeth.

The traditional method for tooth whitening is tooth cleaning in a dental clinic, which mainly utilizes large-scale ultrasonic tooth cleaning equipment to remove dental plaque, tartar and pigment on the surface of teeth, has certain irritation to the teeth, and particularly can cause sensitive symptoms for patients with periodontal diseases, and has other defects, such as time spent on going to the dental clinic and booking queuing, nervous atmosphere in the dental clinic, equipment with too strong metal feeling and sharp sound, and sanitary problems worried by many people.
