Parts of Braces

  • Appliance:
    Anything your orthodontist attaches to your teeth that moves your teeth or changes the shape of your jaw.
  • Archwire:
    The metal wire that acts as a track to guide your teeth as they move. It is changed periodically throughout treatment as your teeth move to new positions.
  • Band:
    A metal ring that is cemented to your tooth, going completely around it. Bands provide a way to attach brackets to your teeth.
  • Bond:
    The seal created by orthodontic cement that holds your appliances in place.
  • Bracket:
    A metal or ceramic part cemented (“bonded”) to your tooth that holds your archwire in place.
  • Coil Spring:
    A spring that fits between your brackets and over your archwire to open space between your teeth.
  • Elastic (Rubber Band):
    A small rubber band that is hooked between different points on your appliance to provide pressure to move your teeth to a new position.
  • Elastic Tie:
    The tiny rubber band that fits around your bracket to hold the archwire in place. They come in a variety of colors.
  • Headgear:
    Headgear uses an external wire apparatus known as a facebow to gently guide the growth of your face and jaw by moving your teeth into proper position. The force is applied to the facebow by a spring-loaded neck strap or head strap. The straps have a safety release that disconnects if the facebow is pulled or snagged.
  • Headgear Tube:
    A round, hollow attachment on your back bands. The inner bow of your headgear fits into it.
  • Hook:
    A welded or removable arm to which elastics are attached.
  • Ligature:
    A thin wire that holds your archwire into your bracket.
  • Lip Bumper:
    A lip bumper is an archwire attached to a molded piece of plastic. The lip bumper holds back the molars on your lower jaw to provide more space for your other teeth.
  • Mouthguard:
    A device that protects your mouth from injury when you participate in sports or rigorous activities.
  • Palatal Expander:
    A device that makes your upper jaw wider.
  • Retainer:
    An appliance that is worn after your braces are removed, the retainer attaches to your upper and/or lower teeth to hold them in place. Some retainers are removable, while others are bonded to the tongue-side of several teeth.
  • Separator or Spacer:
    A small rubber ring that creates space between your teeth before the bands are attached.
  • Tie Wire:
    A fine wire that is twisted around your bracket to hold the archwire in place.
  • Wax:
    Wax is used to stop your braces from irritating your lips.
