Cavities on children’s, primary, teeth are just like that in an adult in that they can cause tooth pain when they become large. It is very important to address the cavities with fillings when these cavities are small to prevent tooth pain and ultimately baby tooth root canals. It is also not recommended to “just pull” the tooth. One of the main roles of a baby tooth is to be a place holder for the up and coming adult tooth. If a baby tooth is pulled before it is ready to come out, the teeth around it will shift and close up the space that meant for the adult tooth. This will mean that there will be crowding in the child’s adult teeth that may not have occurred had the tooth been saved.
