Orthodontic elastic separators (also known as tooth separators or space maintainers)
Purpose: They are small rubber or elastic rings placed between tight teeth (usually molars) a few days before placing orthodontic bands or braces to gently push the teeth slightly apart.
Material: Made from medical-grade elastic polyurethane or rubber.
Shape: Molded in a continuous "S" or chain-like strip so individual rings can be stretched and inserted into the interdental space.
