Gastroesophageal reflux disease (GERD) is a gastrointestinal disorder in which 
stomach acids are chronically regurgitated into the esophagus and oral cavity. 
Continual exposure of the teeth to these acids can cause severe tooth wear. 
Dentists are often the first healthcare professionals to diagnose dental erosion 
in patients with GERD. This article presents a case report of a 27-year-old male 
smoker with tooth wear and dentin sensitivity caused by GERD associated with 
bruxism. After diagnosis, a multidisciplinary treatment plan was established. 
The initial treatment approach consisted of medical follow-up with counseling on 
dietary and smoking habits, as well as management of the gastric disorders with 
medication. GERD management and the dental treatment performed for the eroded 
dentition are described, including diagnosis, treatment planning, and 
restorative therapy.
