With oral sedation a pill is prescribed for you which you will take two hours before your appointment to relax you. In addition to the pill, nitrous oxide, or laughing gas, will be administered along with a local anesthetic (shots). You will still feel the shots, or injections, to numb the areas. With this technique you are more relaxed, however, you are still awake. If you are mildly anxious, this is a good choice. If you choose this method you will need a driver to and from your appointment.
