Most people think acid reflux is a problem of the stomach or esophagus. What often goes unnoticed is its effect on the teeth.
Each reflux episode can expose the mouth to stomach acid with a pH low enough to gradually dissolve minerals from tooth enamel. Unlike cavities, which are caused by bacterial acids, dental erosion from reflux is a direct chemical attack on the tooth surface.
The damage typically occurs slowly over years. Teeth may become thinner, smoother, more transparent, and increasingly sensitive as enamel is lost. In advanced cases, the underlying dentin becomes exposed, accelerating wear and altering the natural shape of the teeth.
For some patients, the first visible sign of chronic acid reflux may appear not in the chest—but in the smile.
