When it comes you your baby teeth you want to take care of them right away. Once the teeth begin coming in, start taking care of them right away. Sadly many parents think baby teeth are not important because they are eventually replaced by permanent ones. But these first teeth preserve the spacing for the permanent ones and help baby chew and talk. If they are not cared for properly they can decay, leading to a gum infection called gingivitis, which can affect the spacing of permanent teeth.
