Hello, 20 deciduous teeth in 4 groups need to be replaced. Generally, the order of upper teeth replacement is 1-2-4-3-5, mainly to ensure that canine teeth (tiger teeth) have enough space when growing. So if the order is wrong, it may cause malocclusion, which may be canine teeth protruding, or the second tooth may be twisted or twisted.

I suggest you go to the children's stomatology department of a regular stomatological hospital for examination. It is best to intervene or treat as soon as possible, otherwise the later the treatment, the more difficult it will be and the more money it will cost.

I hope I can help you!
