Stomach Acid and Tooth Erosion in Reflux

The Mechanism of Acid Erosion

  • When stomach contents reflux into the mouth, hydrochloric acid from the stomach comes into direct contact with the teeth.
  • Stomach acid has an extremely low pH (typically between 1.5 and 3.5), making it far more acidic than the acids found in normal dietary foods and beverages.
  • Because tooth enamel begins to demineralize at a pH below approximately 5.5, repeated exposure to this highly concentrated gastric acid will rapidly dissolve and erode the protective enamel layer.

Key Contributing Factors

  • Frequency of Reflux: Chronic exposure—such as in chronic GERD or frequent vomiting—leaves insufficient time for saliva to neutralize the acid and remineralize the teeth.
  • Salivary Function: Adequate saliva is crucial because it contains minerals and buffering agents that help neutralize acids; reduced saliva flow significantly accelerates enamel destruction.
  • Mechanical Abrasion: Brushing teeth immediately after a reflux episode can worsen the damage, as the acid temporarily softens the enamel, making it easily abraded by toothbrush bristles.

Clinical Recommendations

  • Neutralize, Do Not Brush Immediately: Instead of brushing right away after reflux, rinse the mouth thoroughly with plain water or a solution of baking soda and water to help neutralize the remaining acid.
  • Address the Root Cause: Effective management must focus on reducing the underlying causes of gastric reflux to protect both the esophageal lining and the dental structures from ongoing chemical damage.
