Me. I'm with Marie13 on this one. My dentist knows about my gag reflex and tries very hard not to gag me.
Have you ever had to get an impression made for something? I did about 10 years ago. Small jaw so they had to use a child-sized tray. Then they fill it with the squishy medium and you sit in the dentist’s chair holding the thing, trying desperately not to gag. I actually threw up. Thing had to be redone. I managed not to throw up on the second time around.
Yuck.
