A 33 year old male patient came to the outpatient Department complaining of the bad appearance of his upper left central incisor tooth. He had no history of trauma in that area but the tooth was discolored gradually (Figure 1A). Furthermore, the tooth was asymptomatic. There was no pain and discomfort during mastication. The patient had gastric irritation for the last 5 years and still using omeprazole irregularly. The clinical examination indicates that the left central incisor tooth was yellowish in color and the dentine was found to be exposed (Figure 1B). There was gross tooth tissue loss at the labial surface that includes the incisal edge of the tooth.
