If the patient has been appointed on a particular time and if he/she is waiting since long beyond that time, you are definitely answerable to him/her. You can try explaining the patient politely that you took a little long on a particular patient because of some unavoidable circumstances and may be apologize for the inconvenience caused to the patient. And even after repeatedly explaining the patient he/she doesnt budge, then you must start being stern and put across your point strongly. Even then if the patient doesnt listen, then i think you must ask her to see some other dentist.
