The story of a boy with 27 teeth.

28-32 permanent teeth, including 0-4 wisdom teeth.

There are 28 cases with normal occlusion function, which means one is missing. Your question is not very clear. Tell me what you want to ask.

If the child has just changed his teeth, it is best to take him to the hospital for examination to see if he can help the teeth germinate by artificial germination.
