My LO had a fall and her front tooth got pushed back slightly into her gums.. Anyone has similar experience and can advice if the her dental growth will be affected. ?

This should help you: http://www.deardoctor.com/articles/guide-to-dental-injuries/page3.php The article basically says your child will need treatment within 6 hours for a painful injury that involves the tooth being moved from its position. So please get in touch with a dentist soon as you can.
