Loss of tooth structure associated with chronic regurgitation and vomiting

In summary, a teenaged patient had generalized loss of tooth structure. As the patient previously had a normal dental history and as his family history was negative, many causative factors were quickly ruled out. Finally, after obtaining full cooperation of the patient and reviewing the complete medical records, it was concluded that the loss of tooth structure resulted from demineralization by acidic gastric contents, due to chronic regurgitation and vomiting.
