What do blue rubber bands do on braces?
Blue braces rubber bands are elastic ligatures that hold the orthodontic archwire in the bracket slot, and their color is a cosmetic choice.
How do blue ligatures keep the archwire engaged?
The ligature surrounds the bracket wings and keeps the archwire engaged so orthodontic forces can guide tooth movement. Elastics may fade or stain with foods and drinks.
How can you look after blue brace rubber bands?
Brush around each bracket, clean under the wire with an interdental brush, and ask the orthodontic team to replace a loose or broken ligature.
When should a blue brace band or wire be checked?
Contact the orthodontic team for a wire or ligature that cuts the cheek, a bracket that detached, or pain that is severe or does not settle.
What should you ask about bands between appointments?
Ask whether the bands are ligatures or interarch elastics, what cleaning tools fit, and what to do if one comes off between appointments.
