Nowadays, when it comes to issues related to children's malocclusion, parents are very anxious and worried about affecting their children's appearance in the future. Many parents are prone to panic when encountering some "abnormal" phenomena in their children's dental development process. Actually, parents don't need to worry excessively. Today, we will talk about some "abnormal" dental malocclusion phenomena that may occur during several stages of children's dental development, focusing on their age growth and growth. The teeth that sprout from the fetus at birth are called "birth teeth", and the teeth that grow during the neonatal period are called "new teeth". The two are collectively referred to as early eruption of deciduous teeth, which is more common in the mandibular incisors. Most of these are normal teeth, and a few are supernumerary teeth. Most of the early sprouted baby teeth have no roots or underdeveloped roots, with obvious looseness. Principle of handling: If the baby teeth that emerge in early infancy are extremely loose and there is a risk of loss or aspiration, it is recommended to remove them. If the baby teeth are not significantly loose, repeated friction between the lingual frenulum and lingual abdomen with the lower front teeth during feeding can cause traumatic ulcers. If the ulcer recurs and is difficult to cure, affecting feeding, parents should take the baby to the hospital for treatment and remove the early onset baby teeth. What needs to be identified is that there may be millet sized hemispherical keratins on the alveolar mucosa of newborns, which are white or gray white in color and called upper skin beads, with quantities ranging from one to dozens. This condition does not require treatment and the baby can detach on its own within a few weeks after birth. In the early stages, a child's baby teeth may develop a condition of "overgrowth". According to the pathogenesis, "Dibaotian" can be divided into three types: odontogenic, functional, and osteogenic. Orthodontic malocclusion is caused by misalignment of teeth. Functional malocclusion refers to the condition where the upper and lower jaws are normal, but functional anterior displacement of the lower jaw leads to anterior malocclusion. Osteogenic retrognathia is caused by underdeveloped maxilla or overdeveloped mandible, or both. Treatment principle: Early detection and treatment. Some odontogenic "overbite" will automatically adjust to a normal relationship after the upper and lower incisors are replaced. There are also some cases of 'earth wrapped sky' caused by bad habits that can be observed and do not require early intervention. If parents can urge their children to change bad habits, their child's "overbearing" problem can be returned to a normal bite relationship on its own. Another situation is that children under the age of 3 who cannot cooperate with oral examination and treatment can also be observed first. The eruption of the mandibular anterior teeth in children occurs earlier than that of the maxillary anterior teeth, and the mandibular permanent anterior teeth erupt from the lingual side of the mandibular anterior teeth. As the mandibular permanent anterior teeth erupt, the root of the mandibular anterior teeth will gradually be absorbed, leading to loosening and detachment. At this stage, parents often feel anxious and eager to take their children for medical treatment because they are worried that their children will have "double row teeth". In fact, most permanent incisors that erupt on the lingual side can be adjusted on their own, and deciduous teeth fall out on their own without the need for urgent treatment. If the above situation occurs, parents need not panic and can regularly observe their child's dental development. Prevention of "double row teeth": 1. Choose to eat foods that require chewing and have chewiness to promote the development of the chewing system. 2. Develop the habit of brushing teeth and flossing at least twice a day to prevent dental caries from causing crowding in the dental arch. 3. Parents should develop the habit of regularly checking their children's oral hygiene. If they find that their child's lower permanent incisors have already popped out but the lower mammary incisors are still not loose, they should take their child to the dental department for treatment in a timely manner. With the eruption of the upper permanent incisors in children, a "fan-shaped" gap will appear between the two central incisors, affecting their appearance. At this time, parents are often eager to take their children for medical treatment. The main reason for the "fan-shaped" gap in children at this stage is the compression of the root of the maxillary permanent incisor during eruption, which causes the crown of the permanent incisor to shift to both sides, resulting in a "fan-shaped" gap. This situation does not need to be addressed, as the "fan-shaped" gap will gradually disappear after the child's maxillary permanent incisors have erupted into place. However, parents should pay attention to observing whether their children have supernumerary teeth, impacted teeth, frenulum, or gaps that cannot be closed due to poor oral habits. If there is no change and the gap is still increasing during the observation period, parents should take their children for medical treatment in a timely manner. With the eruption of mandibular permanent incisors in children with mixed dentition, the four incisors may appear crowded and uneven. However, at this time, the child is in the period of breast and permanent tooth replacement, and the teeth are often temporarily crowded. At this point, as long as the existing arch curvature between the mesial surfaces of the first permanent molars on both sides is equal to or greater than the total width of the crowns of all subsequent permanent teeth, their crowding and misalignment can be adjusted to their normal position during the process of tooth replacement. However, there are some special circumstances that require attention. In daily life, parents should learn more about oral hygiene knowledge, help their children develop good brushing habits from the moment their first tooth sprouts, and control the intake of sugar in their diet while ensuring their child's normal nutrition intake. In addition, it is important to encourage children to eat more chewy foods to train and enhance their oral chewing function, promote jawbone growth and development, and align their teeth. If a child's teeth develop abnormally, parents should promptly take the child to the hospital for treatment. (New Society)
