Fillings on primary (baby) teeth

What’s the purpose of placing a filling on a tooth that will eventually grow out?

Kids usually lose all their baby teeth by age 12. However, fillings are sometimes required before the tooth falls out on its own, notably in the case of a fracture or an infection. In addition to being detrimental to your child’s oral health, a damaged tooth can also affect self-esteem.


In the case of a cavity, the dentist will use a specialized metal instrument to remove the decay and prevent it from developing any further. Fillings are a simple and economical solution to palliate a condition that can eventually cause pain and be significantly costlier to correct if left untreated.

In the absence of a filling, the cavity will continue to grow and extraction may be the only option. In such cases, a space maintainer will be needed to ensure that the upcoming permanent tooth will have the room needed to properly grow out. Without a space maintainer, the surrounding teeth will begin to migrate and breach the space required by the new tooth, causing it to become misaligned and/or painful.
