Today, Sunday, my 6 year old had one of his top teeth knocked out. His brother and him were playing and they came up at the same time. Anyway, this tiith was already loose, but it appears that there was no root on the tooth. When I look in his mouth I see a little white piece. Could this been the permanent tooth or still part of the baby tooth. Is it an emergency to get him in somewhere today or just make an appt. with the pediatric dentist this week?
