Orthodontic Spacer - Purpose

Purpose

Spacers are usually used to put spaces in between teeth before braces are established. It can be agitating or painful, but patients are often warned not to pick at them or they will fall out. They are usually rubber, but sometimes they can be metal. They can be used when a patient's teeth are too close together. Although they are sometimes very painful, they are usually only in place for one to two weeks. Spacers can also cause toothache and gum pain because of the pressure against the patient's teeth. The gaps that the spacers create are necessary to apply certain appliances or braces. There are two common types of expanders used after the spaces have been made. One, very primitive, model is a metal bar that has a key used to tighten. Secondly, and more contemporary, there is an expander that is two 'L' shaped metal rods, attached at the molars. Brackets fit against the edges. It is secured with a spring in the middle that applies pressure.
