Disposable needles for dental local anaesthesia do not break easily. Still, needle breakage does occur, and is mainly caused by unexpected movements of the patient or pre-use bending of the needle by the dentist. If a dental needle breaks while administering local anaesthesia, the dentist should prevent panic. If the patient opens his mouth wide the needle might still be visible. If so, the needle is removed. If the needle is no longer visible, the site where the needle has penetrated the mucosa should be marked with a permanent marker. The dentist will contact a maxillofacial surgeon for immediate consultation. The maxillofacial surgeon will try to retrieve the broken dental needle under general anaesthesia.
