5 words for you, you get used to it. For alot of folks(myself included) the 1st time you see certain procedures(most commonly oral surgery procedures) folks will get squeamish. I almost passed out when I saw my first biopsy when I was observing an oral surgeon during my sophmore year of college. After you've seen things though a few times, you get used to it. If your worried about vomit, it really is quite a rare event in dentistry. For most folks, the greatest chance of vomitting while at the office is while an impression is being taken on someone with a sensitive gag reflex. If the vomit issue really concerns you, you might want to rethink the orthodontic thoughts, since in general, an orthodontist will take the greatest number of impressions, thus increasing the chance of the vomit event. It is still quite rare though, my wife, an orthodontist, has roughly 1 vomitting episode in her office every 8 to 10 months(and they average about 5 to 8 patients a day that they are taking impressions on)
