Incisors are incisors. A six-year-old child with a tooth behind his incisors may have an erupting permanent incisor, which should be extracted to ensure the normal eruption of permanent incisors, or it may be an extra tooth, which should be extracted as early as possible to avoid affecting the eruption and arrangement of other teeth.
1. Permanent incisors: permanent incisors usually start to erupt at the age of 6~8 years old. If the permanent incisors have already erupted and the milk incisors have not yet been lost, the corresponding milk incisors need to be extracted, so as to ensure the normal eruption of permanent incisors and the establishment of a normal occlusion with the opposite jaw teeth.
2. Extra tooth: It is an abnormal number of teeth, which may come from the splitting of too many tooth buds or embryos, and its existence may affect the position of the neighboring teeth, or even prevent their normal eruption, and may also lead to crowding of the teeth, so it should be extracted as soon as possible.
It is recommended to go to a regular medical institution to receive professional treatment.
