Orthodontic spacers are used in orthodontics before braces are applied on teeth, and are put on the molars at the second orthodontic appointment. Spacers are circular rubber bands about a centimeter in diameter placed between top and bottom molars; there may be 1-12 spacers applied. In some cases, an orthodontist may use a metal spacer, which is a small piece of metal that rings around the tooth. The spacers stay between the teeth for about two weeks and move the teeth apart slowly until they are far enough apart that the dentists can fit a tooth brace in between them. Spacers are worn until the orthodontist removes them or if they are removed accidentally, often by the patient who may chew gums and sticky foods which stick to the spacer and pull it out on some occasion. Sometimes, a dentist may use a spacer that is similar to a metal spacer (see above), but is removable and in some cases it may have a key/string to use to adjust the tightnest. These types of spacers are very similar to a retainer because of their ability to be removed. They are taken out before braces are put on. Everyone reacts differently to having spacers between their teeth. If the patient has relatively no space between their molars (or none at all), the spacer may hurt from the irritated nerves in the gum of the mouth. In some cases the spacer digs into the gums and they begin to bleed and swell, for which orthodontists often hand out special anesthetics which numb the pain. Spacers are usually not painful, although pain relievers can alleviate the pain if needed. When spacers are first applied, there is little to no pain at all; but the gum around the tooth often hurts after the first night's sleep.

Application The application process of spacers usually involves stringing floss through the rubber band and placing the spacer between the teeth. There is some pressure throughout the process and some soreness afterwards, but overall the spacer application process is harmless.
