Appliance Profile What Are Separators & Bands?

Before braces are placed on your teeth, separators (sometimes called spacers) are placed between specific teeth to move them apart slightly and create space. This allows our orthodontists to easily place orthodontic bands (like a ring on a finger) on the teeth the following week.

Bands are rings that surround the whole tooth. They are placed on the large back molar teeth, which act as anchors. Since teeth normally contact each other very tightly, a separator is placed on the front and backsides of these molars to move these teeth apart slightly. This allows for easy placement of the band around the tooth.
