Parts of Braces

Appliance
Anything your orthodontist attaches to your teeth which moves your teeth or changes the shape of your jaw.

Archwire
The metal wire that acts as a track to guide your teeth along as they move. It is changed periodically throughout treatment as your teeth move to their new positions.

Band
A metal ring that is cemented to your tooth and goes completely around your tooth. 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 their new position.

Elastic Tie
The rubber band that fits around your bracket to hold the archwire in place. They come in a variety of colors.

Hook
A welded or removable arm to which elastics are attached.

Ligature
A thin wire that holds your archwire into your bracket.

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 and 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.
