What rinse is advised after acid reflux or vomiting?

• A. Baking soda and water rinse
• B. Vinegar rinse
• C. Alcohol rinse
• D. Saltwater rinse

Answer: (A)

After vomiting or acid reflux, the mouth is exposed to highly acidic gastric juice. The aim is to neutralize that acid to protect tooth enamel and the mucosal lining. A baking soda and water rinse provides a mild base (sodium bicarbonate) that reacts with the acid to raise the pH quickly, reducing irritation and the potential for enamel erosion. This simple, safe rinse helps restore a more neutral environment in the mouth.

Other rinses don’t fit this goal. Vinegar is acidic, which would add more acid rather than neutralize it. Alcohol-based rinses can dry out and irritate the mouth, making discomfort worse. Saltwater isn’t neutralizing and can be irritating or less effective at changing the pH quickly. So, the baking soda and water rinse is the best choice for neutralizing acid after reflux or vomiting.
