Is it true that the whiter the teeth, the healthier they are?

Some people not only pursue tooth whitening, but also pursue bright white, bright white as a star. In fact, the natural color of healthy teeth is not so white. The strongest teeth are natural and healthy yellow teeth. Because our teeth are covered with a layer of enamel, the enamel is mainly composed of 95% to 97% calcium-containing phosphoapatite crystals, which are transparent or translucent. The higher the degree of calcification, the more transparent the enamel is. Dentin is pale yellow, which will appear when enamel calcification is completed, so healthy teeth look pale yellow. On the contrary, when the degree of enamel calcification is low and the transparency is low, abnormal white or milky white will appear. Therefore, experts say that the color of teeth suitable for your skin color is natural and harmonious, so not everyone needs to do tooth whitening.

There are several ways to whiten teeth. One is tooth washing and cleaning, which mainly removes tartar and stains attached to the tooth surface and between teeth, exposing the primary colors of teeth and playing a clean and bright role. Tooth washing is a healthy living habit. Washing teeth in a regular hospital will not damage enamel, but also remove tartar and protect periodontal tissue clean and healthy.

Generally, there are two methods for tooth cleaning: one is ordinary ultrasonic tooth cleaning. It uses ultrasonic vibration to break dental plaque, tartar and pigment on the surface of teeth, and at the same time washes away the debris with atomized water, which will not cause harm to teeth; The other is to sandblast the teeth of people with more pigment on the tooth surface and people who smoke frequently, and thoroughly clean the teeth with high-pressure sandblasting.

The second is chemical bleaching, such as cold light whitening. Apply a special whitening agent to the surface of teeth, and then irradiate with high-intensity blue light to achieve the purpose of whitening teeth. The third is the patch, which puts a layer of white porcelain on the surface of teeth, which directly brings whitening effect to teeth. It should be noted that tooth whitening is not once and for all. In our life, we eat many colorful foods, such as coffee, soy sauce, tea and so on. Will slowly re-stain the teeth.
