Dental caries commonly known as "cavities" or "decay", the real cause is not yet clear. Dental caries is under the influence of a variety of factors; hard tissue demineralization of inorganic, organic matter decomposition, resulting in tooth tissue defect of a disease. Characterized since the beginning of tooth decay is the decay part of the color and hardness change, and subsequent tooth tissue defects in the formation of cavities substantive, deep lesions continue to develop, can cause dental pulp disease, periapical disease, jaw inflammation and other complications, or even a lesion affecting the oral health of the body.
Whether deciduous or permanent teeth can dental caries, lesions are generally carried out slowly, first occurrence of enamel caries, crown decayed parts of the color becomes dark streak, the tooth surface is not smooth, easy to have tartar buildup. Not feel pain in patients with early tooth decay, cavities develop when the dentin encountered cold, hot, sour, salty, sweet foods occur when the pain (usually pain). If the cavity deep, and bore through to the pulp or near pulp, the nature dental instruments of the stimulus can cause excruciating pain. Often embedded within the cavity of food, unpleasant odor issue of corruption. As the cavity continues to expand, the crown will be a block to collapse, leaving only residual root.
Dental caries since the beginning of the visible enamel was chalky or light brown, rough surface. Further development of the hard tissue of teeth are Pulpitis treated visible sizes, the edge is not the whole hole-shaped defects, mostly black, most of the last visible residues or crown damage.
