Acid Reflux & Dry Mouth: What's the Connection?

Yes, acid reflux can cause dry mouth.

Acid reflux occurs when stomach acid flows back into the esophagus. This can cause a burning sensation, pain, and a sour taste in the mouth. It can also cause inflammation and damage to the esophageal tissue. This damage can lead to dryness of the mouth and throat.

In addition, acid reflux can also cause dehydration, which can further contribute to dry mouth.
