Inappropriate deciduous teeth
The replacement time of deciduous teeth and second deciduous molars is late, and premature extraction may lead to the displacement of other teeth and affect the normal eruption of permanent teeth. Primary teeth with slight dental caries only need to be treated and filled in time, and at the same time, children should be educated to maintain oral hygiene and brush their teeth and rinse their mouths frequently.
A deciduous tooth that must be pulled out
The deciduous teeth are severely decayed and swollen, which has seriously affected children's chewing and health, and should be removed in time. The deciduous teeth and supernumerary teeth that form "double teeth" in the maxillary anterior teeth area should also be removed as soon as possible.
The tooth replacement period has passed and the deciduous teeth have not yet fallen off.
At this time, X-rays should be taken to check whether there are permanent tooth germs. If there is a permanent tooth embryo, the deciduous teeth should be pulled out until the permanent teeth erupt.
