Dietary restrictions should be adhered to on the day of the surgery and the night before. Patients with diabetes and hypertension will be regularly monitored to guarantee their health for surgery. The length of time a patient remains at the surgery center will depend upon the type of surgery. A wisdom tooth extraction is a minimal procedure and should have the patient out within a few hours. Jaw surgery, on the other hand, could keep a person at the hospital for a few days. A surgeon will inform the patient ahead of time, so they can prepare.
