My child’s decayed baby tooth will fall out anyway so why should I get it filled?
Some baby teeth will be in your child’s mouth until age 12 and the decayed tooth that needs to be fixed may be one of those.
Decayed, broken or teeth that are infected can hurt your child’s oral and overall health and it may also affect the way your child feels about him or herself now and in the future.
To do a filling, the dentist removes the decay and “fills” the hole with metal, plastic or other material. A filling can be a cheap and easy way to fix a problem that could be painful and cost more later because it stops decay from spreading deeper into the tooth.
If a filling is not done and decay spreads, the tooth may need to be pulled out. If this happens, your child may need a space maintainer to hold space for the permanent tooth.
When a baby (or primary) tooth is missing, the teeth on each side may move into the space. They can block the permanent tooth from coming in. To hold the space, your dentist may put a plastic or metal space maintainer on the teeth on each side of the space, to keep the teeth from moving in. (CDA)
