Characteristics of dental caries

summary

I am breast-feeding, tooth decay, pain! Fill, through treatment, teeth are good, the following on my experience to share with you, the characteristics of tooth decay.

Characteristics of dental caries

First, the prone sites of dental caries are closely related to whether food is easy to be retained. Some sites on the surface of teeth are not easy to be cleaned, and bacteria and food debris are easy to be retained. There are more plaque accumulation, which is easy to lead to the occurrence of dental caries. These sites are the prone sites of dental caries, including pit, fissure, adjacent surface and tooth neck.

Second: the pit and fissure of teeth is a defect left in the process of tooth development and mineralization, and it is also the primary site of dental caries. The adjacent surface of teeth is second only to the pit and fissure, which is generally caused by food impaction due to the wear of adjacent contact surface or the atrophy of interdental papilla.

Third: the neck of tooth is the junction of enamel and dentin, which is conducive to the retention of food and bacteria. It is also a weak link of tooth tissue, especially when the enamel is not in contact with cementum and the dentin is directly exposed, it is more prone to caries.

matters needing attention

Special reminder: vegetables are rich in dietary fiber, through the mechanical friction on the tooth surface, clean the tooth surface. Chewing stimulates salivary gland secretion to reduce food adhesion and plaque formation. So dietary fiber is called "anti caries nutrient". In addition, yellow green vegetables are rich in calcium, which is essential for enamel and dentin calcification. Vegetables also contain many other nutrients, such as minerals and vitamins, which play an important role in anti caries.
