If a bracket or wire breaks during treatment, it's important to contact your orthodontist as soon as possible. They'll be able to advise you on the best course of action, which may involve scheduling an emergency appointment to have the broken appliance repaired.
In the meantime, you can use orthodontic wax to cover any protruding wires or brackets to prevent them from causing irritation or injury to your mouth. Avoid eating hard or sticky foods that could further damage your braces, and practice good oral hygiene to keep your teeth and gums healthy.
