Dental calculus is the oral cavity is not clean plaque and soft scale, in saliva and gingival fluid under the action of mineral salts deposited.
1. Studies have shown that the oral cavity clean ten hours after the formation of plaque, if not clean, bacteria will gradually mature and gathered, under the action of saliva can form dental calculus.
2. Calculus can be deposited in any part of the gums, mainly divided into supragingival calculus and subgingival calculus, in addition to the existence of its own compression of the gums, its rough surface for the bacterial adhesion to create the conditions for the agglomeration of the loose structure within the calculus, which can be adsorbed by a large number of bacterial metabolism clogging, resulting in inflammation of the gums and alveolar bone resorption.
Therefore, standardized good brushing and regular cleaning of the oral cavity is the key to preventing the formation of dental calculus, it is recommended to use the correct way of brushing and go to the regular hospital for gingival cleaning once every 6 to 12 months.
