What is a Space Maintainer?
It is very often a small stainless steel wire and band joined together which is cemented on one of the teeth adjacent to a gap where a permanent tooth should be erupting.
Why is a Space Maintainer needed?
Even though the primary dentition (commonly known as baby teeth) are temporary, it's important to realize how essential they are to the eventual eruption of your child's permanent teeth. Baby teeth play a crucial role in helping kids learn to speak and chew food for nourishment, but they also save space for their adult teeth. This is why, if your child has a badly decayed primary tooth, a stainless steel crown may be the best solution.
How long my child need to wear it?
This all depends on how long it takes for the tooth or teeth to erupt though the gum.
