Introduction: In individuals with gastroesophageal reflux disease, chronic gastric acid regurgitation can induce dental erosion, which, when combined with attrition or bruxism, can result in a significant destruction of coronal tooth structure. Case presentation: this case report, a male patient, 54, with gastroesophageal reflux disease is treated for significant tooth wear. After receiving medical care, it was discovered that he had severe tooth wear, bruxism, and diminished vertical dimensions. The maxillary and mandibular front and posterior teeth were prepped for metal-ceramic fillings once the vertical dimension had been restored. Although all teeth were splinted, full mouth restorations for both the maxillary and mandibular arches were created using metal-ceramic fixed partial dentures. For his experience of bruxism, a maxillary stabilising splint was then created. Conclusion: Coronal tooth structure degradation that is significant must be taken into account. The loss could be brought on by gastroesophageal reflux illness alone or in conjunction with attrition, abrasion, or bruxism. The medical and dental repercussions of the issue require a thorough diagnostic assessment.
