For many dental procedures, patients can choose from one of the following types of anesthesia:
- Local anesthetics: administered by injection and used in general dentistry for procedures like fillings or extractions.
- Nitrous oxide or “laughing gas”: an inhaled anesthesia used in cases where the patient needs more relaxation beyond local anesthesia.
- Conscious sedation combined with local anesthetics: a patient receives medication that creates a drowsy and relaxed feeling, after which a local anesthetic is used.
- General anesthesia: a medication used to place the patient into a deep sleep.
