Separators or “spacers”, as they are more commonly referred to, are used in orthodontics on a daily basis and while simple, they are at the same time an important part of treating patients. Separators work in the following way: they are first stretched thin with a separator plier and flossed below the contact point. When the separator is in place, it tries to return to its normal shape, and in doing so pushes the teeth on either side apart. Typically, separators are placed interproximally around teeth that will be banded, and are left in place for about a week. Some separators include a radiopaque material that is visible on radiographs in case they become displaced too far subgingivally. Sticky, chewy foods should be avoided while separators are in place as they can pull the separators out.
