Following pre-operative instructions is important to ensure a smooth procedure and an easy recovery process. Pre-op instructions for dental surgery differ depending on which procedure you are undergoing and the type of sedation or anesthesia you will receive. Some oral surgery procedures are performed using only local anesthetic, while others involve intravenous (IV) sedation. Following these general guidelines is usually a good place to start. Your dentist can provide you with more specific instructions related to your individual procedure.
