Here are some general guidelines you can follow:
Have a good meal before the wisdom tooth surgery.  As your jaw will be numb for around 3 hours after the wisdom tooth surgery, you will find eating and drinking difficult.
Brush and clean your teeth well.  This will reduce the chance of your wound getting infected after the surgery.
Arrange for someone to take you home after the wisdom tooth surgery.  As the procedure involves anesthesia, you may feel disoriented after the procedure. It will be much safer to have someone bring you home.​​
