Tiny rubber bands known as alastic ligatures (see diagram), are often used to hold the archwire into the bracket or brace. If an alastic ligature is lost, contact the orthodontist, who can advise you whether the patient should be seen.
The same holds true for wire ligatures.
What if the Lip Gets Caught on a Brace?Call your orthodontist immediately.
Apply ice to the affected area until you have the opportunity to be seen by your orthodontist or family dentist.
