An increased gag reflex can be a reason to hate dental appointments. No one likes feeling like they could throw up at any moment! But there is no reason to run away from that needed dental treatment...
The gag reflex is a natural, involuntary bodily response that contracts the muscles in the throat to prevent a person from swallowing food or foreign objects that could cause illness, poisoning, or choking.
In the back of the mouth are structures with very sensitive nerve endings which, when stimulated, activate an area of
the brain that responds with muscle movements and spasms, popularly known as arcades.
