INTRODUCTION: Chronic regurgitation of gastric acids in patients with 
gastroesophageal reflux disease may cause dental erosion, which can lead in 
combination with attrition or bruxism to extensive loss of coronal tooth tissue.
CASE PRESENTATION: This clinical report describes treatment of severe tooth wear 
of a gastroesophageal reflux disease patient who is 54-year-old Turkish male 
patient. After his medical treatment, severe tooth wear, bruxism and decreased 
vertical dimensions were determined. The vertical dimension was re-established 
and maxillary and mandibular anterior and posterior teeth were prepared for 
metal-ceramic restorations. Metal-ceramic fixed partial dentures were fabricated 
as full mouth restorations for both maxillary and mandibular arches because of 
splinting all teeth. And then maxillary stabilization splint was fabricated for 
his bruxism history.
CONCLUSION: Significant loss of coronal tooth structure must taken into 
consideration. Gastroesophageal reflux disease by itself or in combination with 
attrition, abrasion or bruxism may be responsible for the loss. An extensive 
diagnostic evaluation is essential for the medical and dental effects of the 
problem.
