Management of Dental Trauma in the ED - DENTAL ANESTHESIA


Several medications are available to help create more relaxed, comfortable dental visits.

Some drugs control pain, some help you relax, and others put you into a deep sleep during dental treatment.

Local anesthesia is a type of anesthetic used to prevent pain in a specific area of your mouth during treatment by blocking the nerves that sense or transmit pain, which numbs mouth tissues.

Your dentist may apply a topical anesthetic to numb an area in preparation for administering an injectable local anesthetic.

Topical anesthetics also may be used to soothe painful mouth sores.

Injectable anesthetics may be used in such procedures as filling cavities, preparing teeth for crowns or treating gum disease.
