Local anesthesia plays a vital role in ensuring that dental treatments are not only effective but also comfortable and well-tolerated by patients, thereby promoting better oral health and overall well-being. Allowing dental hygienists to administer local anesthesia will expand dental access and increase patient comfort.
In this article, we will break down the different types of local anesthesia that is administered in dentistry. We also list the exact states that allow dental hygienists to administer local anesthesia.

Local Anesthesia in Dentistry
Before breaking down the states that allow dental hygienists to administer local anesthesia, it’s important to understand the different techniques used. Certain states have placed restrictions on dental hygienists and how they can administer local anesthesia.
The choice between block anesthesia and infiltration anesthesia depends on factors such as the dental procedure, the location of the tooth, and the patient’s individual needs and preferences. Dentists and dental hygienists carefully consider these factors to provide effective and comfortable anesthesia during dental treatments.
Infiltrate Technique
Area of Anesthesia: Involves injecting the anesthetic solution directly into the tissues around the targeted tooth. This provides localized anesthesia to a specific tooth and its surrounding tissues.
Nerves Targeted: Targets smaller nerve branches and is typically used for more isolated procedures involving one or a few teeth.
Site of Administration: Administered directly at the site of the dental work, near the tooth or teeth requiring anesthesia.
Type of Dental Procedures: Commonly used for restorative procedures involving one or a few teeth, such as fillings or simple extractions.
Onset and Duration: Generally has a slightly slower onset compared to block anesthesia but is often sufficient for shorter procedures.
Patient Experience: Typically results in localized numbness, affecting only the area around the targeted tooth.
Block Technique
Area of Anesthesia: Involves the injection of anesthetic solution near a nerve trunk or a major nerve bundle. This results in anesthesia of a larger region served by that nerve. For example, a mandibular nerve block can be used to anesthetize an entire half of the mandible.
Nerves Targeted: Targets larger nerve trunks or bundles, affecting a broader area. Common examples include the inferior alveolar nerve block for mandibular procedures and the maxillary nerve block for maxillary procedures.
Site of Administration: Administered at a distance from the site of dental work, typically near a major nerve trunk.
Type of Dental Procedures: Often used for extensive procedures involving multiple teeth or a quadrant of the mouth, such as extractions or surgical interventions.
Onset and Duration: May have a faster onset due to proximity to major nerve trunks. Duration can be longer compared to infiltration anesthesia.
Patient Experience: May result in a larger area of the mouth being numb, affecting speech, eating, and facial sensation on one side.

States that Do Not Allow Dental Hygienists to Administer Local Anesthesia
There is only one state in the United States that does not allow dental hygienists to administer any type of local anesthesia. Delaware does not allow dental hygienists to administer local anesthesia to their patients because the local jurisdiction dictates the scope of practice of dental hygienists and other dental professionals.
Although this is a significant barrier for dental hygienists to expand their reach of patient care, they can still utilize topical anesthesia to help support their patients during treatments. With the help of their supervising dentists administering local anesthesia, dental hygienists can provide the best care to their patients.
States that Allow Dental Hygienists to Administer Local Anesthesia
Dental hygienists have extensive knowledge of head and neck anatomy including the nerves, muscles, and other components that make up the human body.
Expanding the scope of practice beyond the current states that allow dental hygienists to administer local anesthesia to include all areas can improve patient care and expand dental access to underserved areas.
