[|Human|] I heave and retch when the dentist puts a cast in my mouth to take an imprint. It is worse if he tries to align the cast and touches my palate in the process. I still have some work to be done on my teeth and I dread my next visit to the dentist. Any help will be much appreciated.
[|AI|]  Thanks for your query, I have gone through your query. It is a common problem in most of the patients when they take impression for the upper arch. It can be avoided by applying topical anesthetic over the palate and take the impression. You have to divert your mind by counting from 1 to 10 during impression making, or you should keep looking at your toe during impression making. These methods will divert your mind and procedure can be completed without troubling you. I hope my answer will help you take care.
