A couple of tricks we use in my office for gaggers and impressions
#1 I full agree with the prior advice of head down a bit, and telling the patient to wiggle their toes
#2 I will actually lightly tap with my fingers on the patients forehead - works as a distraction technique
#3 I start talking about random things, completely unrelated to dentistry and what I'm doing at that moment in time (again it's all about the distraction options)
#4 Most people will seat the tray back to front, try seating it front to back, as that more closely mimics the sensation of how food enters our mouths and works it's way back towards the esophagus
#5 Really get your timing and water temperature down for when mixing the alginate, loading the tray, and getting it seated so it will set as quickly as possible and you can get the quality impression you need - it really is worth doing so trial and error with taking an impression of a typodont arch to get your working time and water temp combo figured out
#6 Be thankful that someday in the likely not too distant future we'll be taking digital scans for just about all impressions and we won't have to deal with gaggers and actual intraoral use of impression material!!!
