Elastics, AKA rubber bands, are small rubber bands that stretch from upper braces to lower braces. They are generally the simplest way to change the bite – relationship of the upper and lower teeth. The orthodontist will prescribe each patient with specific directions on how and when to wear the rubber bands. There are many ways to wear rubber bands, so be sure take time to understand how you will wear yours. Do not look at how your friends wears theirs. Usually they are later into treatment and not every patient needs rubber bands. Generally speaking, they are to be worn full time. That means only taking them out to eat, brush, and when you need to wear a mouth guard. The better they are warn, the faster they will work.
