How long does it take for a child to change his front teeth?

Incisors are the earliest teeth to be replaced. They are replaced at the age of six or seven. Generally speaking, deciduous teeth fall out. Within three months of permanent teeth eruption, auxiliary stimulation can be carried out for permanent teeth that do not erupt, such as gnawing hard food to stimulate tooth eruption. If permanent teeth do not erupt for more than one year within the time of tooth replacement, X-ray examination of teeth is required. If deciduous teeth show premature loss or deciduous teeth decay to form periapical periodontitis, resulting in deviation from normal eruption route when permanent teeth erupt, intervention must be carried out to be able to erupt normally.
