My daughter is 6 going on 7years old. Her bottom central incisors are both loose however she developed a sore that had a green center and when she herself was messing with it a green little ball popped out. It almost looked like a seed. It wasnt a pus color, it was green been before its cooked green and had a little pus in it. Just not sure what type of sore it was or if I need to have the dentist check it out.
