"Quick and Easy Ways to Whiten Yellow Teeth?"

Yellow teeth can generally be whitened through ultrasonic teeth cleaning or improved through cold light teeth whitening. Teeth yellowing may be caused by neglecting oral hygiene or regularly consuming foods with deep colors. One can improve this condition by undergoing ultrasonic or cold light teeth whitening at a reputable hospital. The principle of ultrasonic teeth cleaning involves the use of ultrasonic vibrations and water spray from the cleaning instrument to remove tartar and stains on the teeth, effectively preventing the occurrence of gingivitis and periodontitis, and achieving the effect of cleaning teeth. Cold light teeth whitening, on the other hand, utilizes a combination of hydrogen peroxide and silicon dioxide to remove surface and deep stains from the teeth through oxidation-reduction methods, thereby achieving the goal of teeth whitening.

After teeth cleaning, it is important to maintain good oral hygiene and care. This includes establishing a good habit of brushing teeth morning and night, as well as adjusting one's diet to avoid hard or sticky foods, and instead opting for easily digestible and chewable foods.
