People's requirements for teeth are no longer just "painless" and "occlusion", but "functional and aesthetic". Therefore, more and more people want to use the Spring Festival holiday to whiten their teeth.
To this end, experts reminded that we should have a correct understanding of tooth whitening. Just as there are individual differences in skin color, there are individual differences in the brightness and whiteness of everyone's teeth. That's why dentists have special colorimetric series when choosing colors for patients' dentures, which varies from person to person. We advise you not to blindly pursue "white", but to get out of the misunderstanding that "the whiter the better". Natural and harmonious beauty is the tooth color that suits your skin color.
In fact, brushing teeth is a simple and effective basic method to keep teeth clean and white for a long time. Removing stains and spots deposited on the surface can restore the natural and natural whitening of teeth. The function of friction agent and foaming agent in toothpaste is to remove the dirt on the tooth surface by friction, so as to clean the teeth and refresh the mind. Some toothpastes also add some effective ingredients to slow down the formation of dental calculus and inhibit the adhesion of pigments such as tobacco stains and tea stains on the tooth surface. The correct way to brush your teeth is to vibrate the brush up and down, and repeat each part at least 5-6 times. Choose the right toothbrush, master the correct brushing method and brush your teeth effectively. Usually drink less coffee, colored drinks, smoke less, chew betel nuts, etc. To reduce pigment precipitation. In addition, you can go to the hospital to wash your teeth. Tooth washing means that the doctor will help you brush your teeth thoroughly and clean up the nuances that you usually ignore or are inconvenient to brush.
But for endogenous colored teeth, the above methods are powerless. At present, the commonly used method is drug washing. However, due to the deep dentin, it is not durable and there is a phenomenon of "color rebound". It has little effect on tetracycline teeth and dental fluorosis with heavy color. In addition, you can choose crown restoration, which is simply to coat a bright white coat on the grayish yellow teeth.
In short, the pursuit of tooth whitening under the premise of health is the concept we advocate.
Common sense of dental care
The surface of the crown with normal tooth color is covered with a layer of enamel, which is medically called enamel. The normal thickness is about 2-2.5 mm, and the dentin below is yellow or light yellow. Generally speaking, the higher the degree of calcification, the more transparent the enamel is, and the yellow below it is easier to penetrate and develop color, so the normal and healthy crown is generally yellowish and translucent ivory color. Early childhood deciduous teeth have low calcification and low transparency, showing milky white, which is whiter than the replaced permanent teeth. Even with the same permanent tooth, the color of the tooth gradually turns yellow with the increase of age, so the teeth of young people are whiter than those of the elderly.
The causes of abnormal tooth color are exogenous and endogenous. The former can be due to frequent consumption of food or drugs containing pigments, such as tea, coffee, Chinese medicine and so on. And the pigment is deposited on the tooth surface, or because of frequent smoking, the smoke spots cover up the original tooth color and are dull. Endogenous coloring is influenced by drugs, trace elements or general conditions during tooth development, such as tetracycline teeth and dental fluorosis. If your front teeth are obviously gray and black, you can recall whether you have had bumps or injuries. In addition, the teeth with nerve treatment will also change the color of teeth because of the change of blood supply.
