Not a dentist, so take this for what its worth, but if its not painful, I don't
think much will need to be done. My 3 year old has a chipped front tooth from a year ago. After the initial crying, hasn't been a concern. Its a baby tooth anyway. If its too painful for her to eat, then obviously get it looked at and taken care of. If pain is severe enough, then maybe ER, but if she's OK when not bothering it, could maybe give it overnight.
