This very common question. Many parents of children with cavities is concerned that their child teeth are soft, thus increasing the risk of the cavity. Many parents accuse falsely "soft" teeth poor dental health of their children. Before we answer this question, it must talk about different tissues whose teeth are built.
Teeth are composed of four fundamental tissues: enamel, dentin, cementum and pasta. Enamel, dentin and pulp are the three tissues commonly associated with caries in children.
Enamel is a highly mineralized and white fabric a composition similar to the os, but much more difficult. Enamel is the hardest substance in the human body. Enamel is the protective outer layer of the Crown of the tooth that is initially attacked by acid sugarbugs production, or cavity-causing bacteria. The acids produced by these bacteria dissolve the enamel over time, so that the tissue below is achieved.
Dentin is softer yellowish tissue of the tooth beneath enamel and shape both the Crown and the root of each tooth. This layer of fabric is less mineralized than enamel, contains more protein and more water than enamel, making it more likely to disintegrate. Once the cavity to obtain this layer of tissue that they are moving more rapidly towards the dental pulp, or "nerve" of the tooth. More cavities is progressing in the dentin, becomes more painful tooth.
Dentin in tooth form a Chamber containing nerves, blood vessels and teeth building cells. The fabric in the House is called the root or dental pulp. Once a cavity reaches the pulp, pulp can become inflamed and will possibly be infected unless the treatment is provided.
The root surface is covered with cementum. This is the mildest of three mineralized tissues that make up our teeth. Usually, it is not visible among the children or young adults. However, as we age, cementum can be exposed by the retreat of the gums. It is a very sensitive fabric and react painfully to the physical or chemical stimulation such as brushing or hot or cold food. Most older adults have root surfaces exposed and exposed cementum.
Thus, in the vast majority of children with cavities are soft teeth. However, there are several genetic abnormalities and anomalies caused by disease, malnutrition or infection that may increase the risk for the affected teeth develop cavities. Any change of development affecting the roughness of the surface of the enamel or enamel thickness and dentine can accumulate the risk of cavity increase by making the job easier for bacteria to the surface or enter the tooth. FortunatelyThese conditions are very rare. Parents can question if their child has dental disease hereditary or acquired a dental anomaly if the color or shape of their children is different from what they expect. If you think that your child is affected by one of these rare conditions, ask your dentist to examine your child.
As we explained in previous columns, bacteria and our diet are much more important in the process of disintegration.
What is the bottom line? There are very few people actually having soft teeth. " Do not forget that the teeth and bones are formed of the same minerals - calcium and phosphate. If your child has "soft teeth", they probably also need to "soft" bones Soft bones are sensitive to deformation or fracture. Your family physician will be familiar if your child has abnormal bones. Your dentist will be able to determine if your child has abnormal enamel or dentin.
