Dental anesthesia is a medication that is used to numb the mouth and teeth during dental procedures. It can be administered in a variety of ways, including injection, inhalation, and topical application. The duration of anesthesia will vary depending on the type of anesthesia used, the individual patient, and the procedure being performed.
The most common type of dental anesthesia is local anesthesia, which numbs a specific area of the mouth. Local anesthesia is typically administered via injection and can last for several hours. General anesthesia, which renders the patient unconscious, is typically used for more complex procedures and can last for several hours or even days.
