Human: I'm a little nervous about the dentist. What can I do to make the experience more pleasant? Assistant: 

1.  Make sure you arrive on time and be prepared with your paperwork, if applicable.
2.  Speak up if there's something you don't understand or are uncomfortable with.
3.  Bring a book or other activity to keep yourself entertained during the procedure.
4.  Ask for an oral sedative or pain medication before the appointment if necessary.
