Anesthesia is a medication that is used to prevent pain during a medical procedure. In dentistry, anesthesia is used to numb the area around the tooth that is being worked on. This allows the dentist to perform the procedure without causing the patient any pain.
There are several different types of anesthesia that can be used in dentistry. The most common type is local anesthesia, which numbs only the area around the tooth. Other types of anesthesia include regional anesthesia, which numbs a larger area of the body, and general anesthesia, which puts the patient to sleep. The type of anesthesia that is used will depend on the type of procedure that is being performed.
