Stomach acid from reflux can cause tooth enamel erosion

Prof. Dr. Naime Bilinç Bulucu, Head of the Department of Restorative Dentistry at Biruni University, has warned that stomach acid reaching the oral cavity due to gastroesophageal reflux can cause erosion of tooth enamel over time.

Bulucu noted that repeated acid exposure can lead to the softening of the enamel surface and eventually result in irreversible loss of hard dental tissue. Symptoms of this erosion include thinning of the teeth, flattening of surfaces, pitting, and increased sensitivity to hot, cold, or sweet substances as the underlying dentin becomes exposed.

While enamel is one of the hardest structures in the body, it is not entirely resistant to acid. Bulucu emphasized that lost enamel tissue does not regenerate naturally. She also cautioned that while tooth erosion is a significant concern, it should not be used as a sole diagnostic tool for reflux, as other factors such as acidic beverages, dietary habits, and dry mouth also contribute to enamel loss.
