YES! You have to get their cavities filled. If you don't they will just continue to decay which will be painful and yes that can make them fall out before they are ready and this is very bad. The baby teeth hold space for permanent teeth to come in if they fall out too early it can cause other baby teeth so shift into that open space and then the permanent teeth can't come in. Also if the baby teeth have decay and it isn't taken care of that decay can set in the gums and into the permanent teeth that haven't come in yet. Then once they do they are already bad and will have to be worked on anyways. I was a dental assistant before i became a SAHM so I know this all to be true. And most dentist will due payment plans with you so I know it will cost a lot but you have to get them fixed!
