When children are missing teeth, they first cannot chew food well, which increases the burden on the gastrointestinal tract and can lead to digestive problems and other gastrointestinal diseases. In terms of the oral cavity specifically, missing front teeth can significantly impact both aesthetics and development. If back teeth are missing, the vertical distance of the lower third of the face on the side of the gap shortens, causing facial asymmetry. Additionally, prolonged tooth replacement time can result in the jawbone losing physiological functional stimulation due to the lack of normal occlusal relationships, leading to jawbone resorption and causing jaw deformities. Another important point is that neighboring teeth on either side of the gap tilt towards the missing tooth area, affecting orthodontics and hindering the eruption of permanent teeth, resulting in dental and jaw deformities. Therefore, when children are missing teeth, it is timely to get them fitted for dentures, as this is very important for their future growth and development. Since a child's dental arches and face have not yet fully developed, with the development of the jawbone and the eruption of permanent teeth, regular hospital check-ups should be scheduled to decide whether to remove or replace dentures.
