A lifetime of strong oral hygiene begins with good dental habits in childhood. While it is true that baby teeth eventually fall out, they play an important role in allowing your child to chew and speak. If a baby tooth decays and falls out prematurely, it may cause the other teeth to shift out of place and lead to serious misalignment of the adult teeth. Furthermore, gum health can deteriorate at any early age, with infections getting in the bloodstream and potentially affecting the health of other organs.
