People always ignore the problem of food residue between teeth. Residual food will damage your teeth. If you only care about whitening, you should also pay attention to removing the residue between the gaps, so that your teeth will look whiter. In addition, no matter how white your teeth are, your gums look unhealthy if they are red and swollen, so it is best to clean them once every two days.

Second, eat sugar-free xylitol chewing gum properly

Xylitol is a natural sweetener, which can prevent dental plaque, while ordinary sugar is easy to cause dental plaque. Xylitol can also balance the acid-base balance in the mouth and promote saliva secretion. Saliva is a natural cleanser in our mouth, which can clean all gaps. But there are two sides to everything: saliva can clean food residues and bring bacteria. Therefore, it is necessary to brush your teeth twice a day and take a sugar-free xylitol chewing gum after meals in order to whiten your teeth.

Third, cold light can be used to whiten teeth.

Cold-light tooth whitening technology is to transmit high-intensity blue light with the wavelength of 480—520nanaometer through12,000 optical fibers with a total length of more than one mile, and then through two optical lenses which have been coated for more than 30 times, all harmful ultraviolet rays and infrared rays are excluded and irradiated on the special whitening agent applied to teeth, so that the whitening agent can penetrate through the dentinal tubules of teeth and be deposited on the surface and deep layer of teeth for many years in the shortest time.
