i can very well understand your agony . it seems the wound comprise of facial hard and soft tissue
one more thing is evident here, your daughter has nerve injury
the filling of freezing is due to numbness
. don't worry nerves take several weeks to heal. as the wound start healing she will feel better.
also see a dentist
to make sure that her maxilla
is intact, as the fractured maxilla can cause pressure on nerves and further damage it.
generally plating is done for around seven to eight weeks.
oral splinting is done to stabilize the teeth and immobilize them. just take care that there should be no further infection.
be positive and be optimistic . i am sure with time, it will heal, and she will be fine.
