Hi!! If ur child is Unable to close mouth, their could be many reasons of it, one short upper lips or probably she might be a mouth breather. If so I need to see a Pediatric dentist and rule out to avoid further future problems of the anterior teeth.

Namaskaram, Your kid is at a age where some of her temporary teeth are replaced with the permanent ones . This is called the Mixed dentition period. In this age she will have some teeth which are slightly structurally and functionally different from her temporary teeth . You can consult an orthodontist who can run a clinical examination and suggest you with a couple of x rays as how her permanent teeth are placed and the need for treatment for the best smile .
