What should I do if my bracket comes off?

You will need to contact your dental clinic and get it reattached. Of course, try not to swallow the bracket in the first place. If this happens, your bracket will go through your digestive system and come out with defecation; it has no toxic side effects for your body. Most dangerous situation is to have your bracket stuck in your respiratory system; in this case you must immediately see a medical doctor as you may be in need of bronchoscopy.
