Calculus, commonly known as "teeth rust", which is more firmly attached to the tooth surface calcium deposits, brush your teeth do not brush, plaque plaque mineralization is the result of the oral cavity by bacterial plaque is the main body very dense and very thin transparent film, most likely attached to the neck teeth, gum edge, and pit and fissure tooth surface rough place, plaque staining agent required to see the show.
Fast formation of plaque, tooth brush to clean off a few hours, the teeth soon form a thin layer of membrane, bacteria breed quickly in the above development, plaque formation, the calcium in saliva can be gradually precipitation on the inside, a long time, become hard like a stone plaque, very firmly attached to the teeth, plaque calcium is mainly in the saliva, the plaque is often so close to opening the site particularly the salivary glands, such as the maxillary first molar buccal and lingual plaque under a lot of front teeth.
Plaque surface is always covered with a layer of plaque, tartar under the microscope to observe the rough surface is porous, so the accumulation of plaque and calculus to dental equipment provide favorable breeding conditions, a large number of plaque bacteria to multiply and produce toxins, and bacteria break down food residues, but also harmful substances, pathogens, toxins and harmful substances, destruction of the gums (known as "tooth") organization, resulting in gingivitis, gingival swelling, easy bleeding when brushing your teeth, bite bread or severe fruit can also cause bleeding in the food left on the bloodstain. Continue to develop gingivitis, periodontal tissue invasion and deep, may develop periodontitis, then in addition to red, swollen gums, but also appeared periodontal pocket, and the overflow pus, alveolar bone loss, loose teeth and displacement, affecting chewing function and digestion of food.
Pay attention to oral hygiene, sooner or later develop good brushing habits and the correct method of brushing, and regularly to the hospital, scaling, prevent plaque and tartar formation, prevention and treatment of gingivitis.
