S.G.
I have 4 children. If they are teeth that she will be losing in the next year or two. Don't do anything to them. I'd never crown baby teeth. Small fillings don't even need to be fixed as long as you keep a good watch on them and brush them well every night. Play dentist before bed and use a flash light. If they don't seem to be getting worse, leave them alone. They'll fall out before you know it.
Good luck,
S.
