Calculus is attached to the teeth on the lump foreign bodies, such as the rusty water in the kettle, also commonly known as tooth rust. Human oral bacteria in a wide variety and complex, often tooth surface by the attachment of bacteria and sediments of the formation of plaque, the sticky great, the general cleanliness measures, such as mouthwash, can not be washed to remove , Such as dental plaque in the long-term retention level, will gradually shedding of necrotic tissue cells, WBC, in the mucus of saliva, such as proteins attached to its off-white or yellow on the formation of the debris, with the saliva and serum calcium Salt deposited with them gradually, prompted debris calcification harden into calculus. Therefore, the calculus is from minerals (calcium, magnesium phosphate, calcium carbonate, etc.) and organic matter (protein, fat, loss of epithelial cells, WBC, microbiology, food residues). Calculus at the surface of teeth and neck, gingival margin to captain on the subgingival calculus, gingival margin for the following subgingival calculus. Subgingival calculus on the Changcheng yellow or off-white, but also because of smoking or food coloring pigment into the dark. Calculus easily deposited in the salivary duct openings relative tooth surface, as anterior Shemian (inside) and on the cheek teeth (lateral). In addition, the calculus is also deposited on the loss of functional chewing surface of teeth, such as the wrong habit of chewing teeth and unilateral non-functional side of the teeth and maxillofacial.

As calculus is the best plaque at the site, the calculus has a more easy absorption of bacteria toxin. These bacteria and toxins and stimulate the long-term calculus of local, can gum inflammation, in the gingival tissue edema and congestion, gingival margin erosion, bleeding gums is easy. Patients in eating, or even speak, sucking at the bleeding gums, and severe cases, get up early morning after Manzui covered with Blood-streaked phlegm. So when the timely removal of calculus, gingivitis, will gradually turn for the better or cured, such as patients did not receive timely treatment, will continue to develop gingivitis, periodontal tissue caused by excess pus, bad breath does not apply there, the destruction of the alveolar bone absorption, shrinking gums, root Exposure of teeth loose, for the development of periodontitis. So the existence of calculus is very harmful. So how to prevent the formation of this calculus » We have said before calculus is due to the formation of plaque attached to the tooth surface beginning, so to prevent the formation of calculus, should be:

① remove dental plaque surface, the easiest and most effective way is to carefully brush their teeth. Information shows that high-quality brush teeth surface can be removed more than 90 percent of the plaque and debris.

② adjustment should pay attention to diet structure, less consumption of soft and sticky food, especially children eat less high-sugar foods, eating more appropriate and more fibrous food, to increase the teeth of the self-cleaning, reducing plaque formation.

③ treatment dentition missing teeth crowded, dislocation and eliminate the bad habit of chewing unilateral, so that all the teeth are chewing its function.

④ should be every six months to a year to the hospital for dental check 1
