A 7-year-old child who has replaced two teeth and stopped losing them can be observed for 3 to 6 months, and if the condition does not improve, he or she can go to the stomatology department of a regular hospital for an oral examination. Children usually change their teeth between the ages of 6 and 12, and there will be individual differences. First of all, you can take your child to the dentist for a checkup, and if necessary, you can take a panoramic film of the mouth. These full mouth films allow you to see how the teeth are being replaced throughout the mouth, to see exactly where the lower permanent teeth are in relation to the milk teeth, and whether or not the replacement is imminent. Need to pay attention to during the replacement of teeth: just erupted permanent teeth if there is a slight malposition, misalignment, is a normal phenomenon, the teeth will also be adjusted by themselves; if the milk teeth are prematurely removed, we must do gap retainer to prevent misalignment of teeth; six-year-old teeth in the eruption of the fossa is recommended to do the fossa closed to prevent dental caries. Seven-year-old children replaced two teeth do not fall out, there is generally no problem, you can observe a period of time, the symptoms did not improve, timely medical care.
