Why are deciduous teeth lost early?

Deciduous teeth are a child’s first set of teeth. Most children begin to have their deciduous teeth replaced when they are five or six years old, followed by permanent teeth. The normal replacement of deciduous teeth and permanent teeth is a prerequisite for normal tooth replacement, but many children lose their deciduous teeth, which causes the inherited permanent teeth to fail to erupt normally, thus affecting the neat arrangement of teeth. What exactly is the cause of premature loss of deciduous teeth? The editor will introduce the reasons in detail below.

Causes of premature loss of deciduous teeth

1. Severe caries that cannot be retained and must be removed: Severe caries only leaves residual roots; caries causes chronic apical inflammation, a lot of alveolar bone absorption around the root, a large lesion and no hard bone plate separating the permanent tooth germ below it, so it cannot be retained through treatment; inflammation affects the development of the permanent tooth germ

2. Or inflammation causes premature absorption of the roots of deciduous teeth.

3. Ectopic eruption of permanent teeth: commonly seen in the maxillary first permanent molars. Because the first permanent molar tilts forward and erupts, it presses on the root of the second deciduous molar, causing the root to be absorbed and cause it to loosen and fall off.

4. Teeth fall out or are extracted due to trauma: Children are mostly active and lively, and are prone to bruises and falls. The roots of deciduous front teeth are shorter and are easily displaced or dislocated when impacted by external forces, often accompanied by alveolar bone fractures. Because the crowns of deciduous incisors are shorter, they are difficult to retain and difficult to ligate and fix. In addition, the roots of deciduous incisors are short and have poor retention. If they are displaced, they are usually extracted.

5. Congenital tooth loss: such as "ectodermal dysplasia syndrome" is a hereditary disease.

Countermeasures for premature loss of deciduous teeth

Once a child loses his or her deciduous teeth prematurely, parents should take the child to a pediatric dental specialist clinic for examination and take X-rays to determine the development of the permanent tooth germs. The roots of premature permanent teeth are not developed, which may cause them to loosen or even fall out when biting hard objects. The enamel on the surface of prematurely erupted permanent teeth is immature and poorly calcified, making them susceptible to caries. Therefore, a space maintainer is needed to maintain the space between missing teeth, or an inhibitor is needed to prevent the permanent teeth from erupting prematurely.

The above are the causes and countermeasures of premature loss of deciduous teeth. Premature loss of deciduous teeth will reduce chewing efficiency and affect the physical development of the child. Therefore, parents should pay special attention to the changes in their children's teeth. Because children are lively and active, they should be careful to avoid dangerous objects from knocking their teeth. Once premature loss of deciduous teeth occurs, go to a professional pediatric dentist as soon as possible.
