Some people have delicate facial features, but their teeth are irregular, so they can't even smile. So, what factors affect the orderly arrangement of teeth? It's quite troublesome!
Did you know that to have a set of neat and healthy teeth, attention should be paid to dental correction from when the mother is pregnant. If the expectant mother has poor nutrition during pregnancy, lacking essential minerals such as calcium, phosphorus, iron for fetal growth and development, as well as vitamins B, C, D, etc., it may cause fetal developmental abnormalities or malformations.
There are also some diseases that can damage teeth: the health of the baby is the basis for ensuring the development of the craniofacial bones and teeth. Many acute and chronic diseases affect not only physical health but also the growth and development of the cranium, face, and the whole body.
Common infectious diseases in childhood with high fever, such as measles, chickenpox, scarlet fever, etc., can damage the development of tooth-forming tissues, affecting the future shape of the teeth. Chronic long-term consumptive diseases like indigestion, gastroenteritis, tuberculosis, poliomyelitis, etc., severely disrupt the nutritional status of the body, thereby hindering the growth and development of the upper and lower jawbones, causing malocclusion deformities of the teeth and bones, such as maxillary protrusion, mandibular protrusion, maxillary retrusion, mandibular retrusion, etc.
Another disease that seriously affects bone development is rickets. Due to improved living conditions and higher living standards, severe rickets is now rarely seen, but there are still quite a number of mild cases. This disease occurs due to insufficient sunlight exposure in infants and young children, leading to vitamin D deficiency, which causes an imbalance in calcium and phosphorus intake from food. Calcium cannot be normally deposited in the growing parts of the bones, resulting in deformation.
The deformity of the jawbone is manifested as a narrow maxillary arch (insufficient U-shape width), crowded upper front teeth (the six teeth directly above), protrusion, and open bite (upper and lower teeth cannot make contact).
These are all factors that cause irregular teeth.
