The Hidden Dental Damage of Acid Reflux
Acid reflux is usually thought of as a stomach or esophagus problem. But repeated exposure to stomach acid can also wear down tooth enamel.
Unlike cavities, which develop when oral bacteria produce acids, reflux related erosion happens when stomach contents directly contact the teeth. Over time, this acid can dissolve minerals from enamel, the hard outer layer that protects each tooth.
The changes may be gradual and painless at first. As enamel wears away, teeth can look smoother or thinner, become more sensitive, and lose the natural contours of their chewing surfaces. Tooth edges may also appear more translucent.
If erosion progresses, the softer dentin beneath the enamel can become exposed. This may increase sensitivity and leave teeth more vulnerable to further wear or structural damage.
For some people, changes in their smile may be noticed before they recognize reflux symptoms. Because lost enamel does not grow back, early evaluation can help identify the cause and discuss ways to protect the teeth.
If you notice new tooth sensitivity or changes in tooth shape, schedule a dental evaluation. A dentist can assess the wear and discuss next steps with your medical provider if reflux may be contributing.
