Meet my Dentist

This is Dr. Sammons, probably the nicest and best dentist anywhere. I have had two fillings replaced last month. Had part of a tooth break off Sunday. I had an appointment today and after looking at what needed to be done he said I needed to come back again Monday, that it would take about 1 1/2 hours to fix it. Is he serious? He wants me to sit in that chair for that long while he works on me. I have a terrible gag reflex so every minute he is working on me is extremely hard on me and on him also.
