I am out of my home. Can not visit dentist till tomorrow. Please advise any emergency management now . please help.
Hello & welcome, Trauma to upper teeth is very common in child Chat Doctor.  If your daughter is not having any kind of pain, nor there is bleeding or swelling then nothing should be done unless you take her to the dentist except for taking care by avoiding touching those teeth.  From your description it seems that those teeth are intruded by trauma & even if today there is no swelling, it may appear after 24 hrs.  If swelling appears then apply ice externally.  Antibiotics can be given as a preventive measure, but that should be under dentists' guidance. Take care.
