Children with loose incisors are advised to visit the dentist as soon as possible to determine the cause of the loose tooth and take appropriate treatment to avoid the loose tooth affecting the permanent tooth below or the surrounding teeth. Generally speaking, children under 10 years of age with “loose” incisors, mostly due to the displacement or dislocation of baby teeth or newly replaced permanent teeth, need to determine whether the degree of tooth loosening can be fixed to make the fallen teeth “stand firm” again and continue to function. If the tooth is so loose that the doctor determines that it has no retention value, it should be extracted as soon as possible to prevent the child from inadvertently inhaling the loose tooth into the trachea, which may cause life-threatening injuries; after the extraction of the loose tooth, a gap retainer should be made to facilitate the eruption of the permanent tooth or future denture restoration. In the case of children over 10 years old, most of the incisor roots have already formed, and the loose teeth caused by the fall may be due to the fracture of the roots or crowns. In daily life, the child should pay attention to a light and nutritious diet, avoid eating too hard food, pay attention to oral hygiene, and develop the habit of rinsing and brushing teeth.
