People who never clean their teeth lose their teeth fast, and after a closer look, they understand the reason! A dentist took macro photos of naturally falling teeth and sent them to WeChat, causing a lot of onlookers! Under the lens dental calculus can be seen clearly, and even some dental calculus densely covered in the root area. Many dentists have left a message: show these photos to patients, you do not have to explain what is calculus, you know why their teeth will fall out so early. Why do dentists say this? What is the principle? Read on …… The enemy retreats and I advance: calculus spreads downward step by step A tooth, from top to bottom, is divided into three parts: the crown, the neck, and the root. The crown is exposed and is what we can see; the neck, under the gums, cannot be seen; and the root, in the alveolar bone. If a person does not brush their teeth thoroughly, and never clean their teeth, the crown of the tooth is very easy to grow calculus, calculus will accumulate more and more, to the neck of the tooth to continue to progress, which is often referred to as “subgingival calculus”. Over time, from the crown of the tooth gradually spread downward, calculus every progress of some, alveolar bone will shrink some, the tooth will be some loose, over time, the tooth will gradually loose, calculus will slowly spread to the root area. In the end, the tooth will fall out naturally. Regular scaling: effective removal of dental calculus When dental calculus deposits are very thick and tightly attached, brushing can not be brushed off; at the same time, such as a long time without getting rid of, it may cause gingivitis, periodontitis, bleeding gums, bad breath, and ultimately lead to tooth loosening, and even fall off and other phenomena. At this point, it is necessary to remove dental calculus by way of dental cleaning, while dental cleaning can also reduce gingivitis, periodontitis inflammation, found that small imperceptible dental disease, such as more hidden caries, early detection and early treatment. A few small habits away from dental calculus 1, adhere to the brush, at least 2 times a day, 3 minutes each time; 2, every six months for an oral health check; 3, choose a soft-bristled toothbrush, choose the right toothpaste; 4, eat less fine food, such as: cookies, cakes, etc.; (fine food viscous, sugar, high, easy to be deposited on the tooth surface, not only prone to the formation of calculus, but also cause dental caries.)
