What is the direct answer?
Braces elastics may be ligatures that hold an archwire or interarch bands that guide the bite; the type depends on the orthodontic goal.
What does this question mean?
Small ligatures hold the archwire inside a bracket; interarch elastics connect upper and lower hooks to influence the bite. They may be clear, coloured, latex, or latex-free, and their dimensions are selected by the orthodontist.
What can you do next?
Replace ligatures or interarch bands only as instructed and keep them away from heat and contamination. If an elastic breaks, use the prescribed replacement rather than improvising a different size.
When should you seek dental care?
Contact the orthodontic team for a loose bracket, broken hook, persistent cheek injury, or a reaction after wearing a material.
What should you ask the dentist?
Ask what each elastic does, where it attaches, how often it changes, and whether a latex-free option is needed.
