, Suzhou Dongwu Hospital Dental Department: Some people have misaligned teeth, and the causes are numerous, mainly including genetic factors and environmental factors, hence the need for orthodontics. Among these, the environmental factors further include prenatal and postnatal factors.
1. Prenatal factors refer to various influences on the fetus during its growth and development in the mother's uterus. These could be due to nutritional or metabolic disorders in either the mother or the fetus, the mother contracting rubella or viral infections, the fetus suffering from trauma during the mother’s pregnancy, or injuries sustained during childbirth.
2. Postnatal factors refer to influences that occur after birth during the growth and development process. These include multiple aspects:
(1) Diseases: Certain acute infectious diseases or chronic wasting diseases may affect the development of teeth and jawbones. Hormonal imbalances or malnutrition, especially vitamin deficiencies, may also impact the development of teeth and jawbones.
(2) Abnormal breathing and swallowing functions can affect the development of teeth and jawbones.
(3) Bad habits such as thumb sucking, biting the upper or lower lip, tongue protrusion or tongue thrusting habits.
(4) Issues arising during the milk tooth stage or the mixed dentition stage, at an oral treatment center. Problems such as premature loss of milk teeth, delayed shedding of milk teeth, premature loss of permanent teeth, and disorderly eruption sequence of permanent teeth can all lead to misaligned teeth.
