17 Gastro Gaffes: When Ignoring GERD Gets Gravely Gutsy

9. Dental Erosion

The backflow of stomach acid into the mouth can silently erode dental enamel over time. This acid wears down the protective coating on teeth, leading to increased sensitivity, discoloration, and higher risk of cavities. GERD patients may not always notice the reflux reaching their mouth, especially during nighttime episodes. Dentists often detect GERD-related erosion during routine exams, particularly on the back surfaces of teeth. Using fluoride toothpaste, rinsing with water after reflux episodes, and addressing GERD directly can protect oral health and prevent long-term dental complications.

10. Chronic Cough

One of the more overlooked complications of GERD is a persistent, dry cough. In many cases, this cough is not caused by lung or airway disease, but by acid irritation of the esophagus or larynx. This is known as “extra-esophageal reflux.” The cough tends to worsen at night or after eating and may be accompanied by throat clearing or hoarseness. Because it’s often misdiagnosed as asthma or a respiratory infection, GERD-related cough should be considered in patients with no obvious lung findings. Treatment of reflux typically resolves the cough over time.
