In the unlikely event that an anesthetic needle breaks within the patient's tissues, the following steps should be taken:

1. keep the patient's mouth open either by keeping your fingers in the patient's mouth or by using a bite block
2. have the patient close their mouth immediately to avoid having the needle migrate
3. if the broken needle is visible, try to remove it with a hemostat
4. if the broken needle is not visible, have the dentist incise the area to locate the needle for easy removal
