Straighten teeth: Spacers or separators are rubber bands or metal appliances the orthodontist places between the molars in order to separate them...often the teeth are too close together and need to be separated so that metal bands can next be placed around the molars where the rest of the braces will anchor and be attached. The separators can be painful but the teeth soon move a little bit and the pain resolves.
