Orthodontic Elastics (sometimes called just “Elastics” or “RubberBands”) provide a gentle and continuous force that helps move the upper and lower teeth relative to each other. They attach to the hooks on the brackets of your braces, and are removable. You usually need to wear elastics all (or most of) the time for several weeks or months, and change them at least once daily so they maintain their original elasticity.
Elastics come in a variety of sizes and colors. Your orthodontist knows which size is best for your specific situation. If you are allergic to latex, you can switch to latex-free elastics.
Elastics help to correct overbites, underbites, open bites, or other types of jaw misalignments. In addition, they can move a tooth out of alignment or close a space in the mouth. It is important to wear the elastics exactly the way your Orthodontist suggests. Never double up on the elastics or use a thicker gauge — more force is not better, and may actually damage your teeth and cause a setback in your treatment.
