My 19 month old baby has two rotten teeth that what it seems. They are brown she stopped drinking milk at 13 months so all we could give her is juice, gatorade and water. If the put fake teeth will it help

My son was that age and had the same problem. The children's dentist put chrome crowns on the teeth so my son's speech would develop normally, so he could chew his foods well, and to save the space for the permanent teeth. So, yes, get those teeth fixed!
