Description of the disease (onset time, main symptoms, hospital, etc.): I am from Linfen, Shanxi Province, my daughter is 8 years old, two incisors and four teeth in the middle of the bottom have been replaced, the sixth tooth has also grown out, the other teeth have not been replaced, a bit of “ground envelope”, may I ask if it can be treated now? Or should I wait until all the permanent teeth have been replaced before treating them? Hello: The geodontia is a difficult malformation to treat, because 2/3 of patients are caused by growth factors, which is difficult to treat, and 1/3 are caused by non-growth factors, which need to be corrected early. It is difficult to distinguish between them in current medicine, but the orthodontist can still make a general distinction based on his experience. I hope you can find a more experienced orthodontist to evaluate them so that you do not miss the most suitable time for orthodontic treatment.
