Cinnamon gum is a good dessert to get accustomed to. The chewing causes more saliva to be generated in the mouth and throat. Saliva helps to neutralize the acid of the stomach. Chewing gum also helps people to chew more, and this will help to flush away any acid in your esophagus. If you prefer fruit-flavored gum, you can chew that. Mint flavored gum causes the esophageal sphincter to relax, adding to the problem.
