Some dentists prescribe and administer medications to help patients relax during the appointment. Talk to your dentist about your concerns and ask him or her about the possibility of using dental sedation. Sedation dentistry involves the use of medications to allow you to relax and feel sleepy during a dental visit or procedure. However, sedation is not pain medication, so you may still require local anesthesia, depending upon the treatment. There are a variety of sedation dentistry methods.
