The first milk(Deciduous) tooth comes at the age of 6 months, and the first permanent tooth  at the age of 6 years. Mothers should encourage their children to brush twice a day from early age. We have 20 milk teeth and 32 permanent teeth. Both milk and permanent teeth erupt according to a time table, which can have minor individual variations. If for some reason, milk tooth needs to be extracted earlier than schedule, then, Mothers' should visit Dental Surgeon for placement of Space Maintainer. 

The name is self explanatory, it maintains space of permanent teeth, till they erupt in the oral cavity. In, absence of space maintainer permanent teeth can have insufficient space, leading to crowding. It is a simple attachment on teeth, allowing brushing by Kids.
