(HealthDay News) -- A child's smile is always adorable, but braces may be needed to straighten that smile and resolve problems with the pearly whites.

The Nemours Foundation says braces can help treat:

  • Crooked or twisted teeth.
  • Teeth that overlap each other.
  • Teeth that are crowded into a mouth that appears too small.
  • Cases where the upper and lower jaw aren't the same size, causing an overbite or underbite.
