Mineral trioxide aggregate (MTA) has been used in regenerative procedures but observations have indicated that with its use there is dark staining of the tooth structure. This case report describes the treatment of tooth discoloration caused by white mineral trioxide aggregate (WMTA). Revascularization was performed with the use of WMTA in the upper left central incisor. Grayish discoloration appeared 9 months later, the tooth necessitating internal bleaching of the tooth. A significant improvement was observed in the crown after internal bleaching. The choice of material should not rely solely on biological and functional aspects, but aesthetic considerations should also be taken into account. The patient needs to be advised of risks, benefits, and alternatives to internal bleaching, eg, a veneer or a crown. Coronal discoloration is a significant distraction and embarrassment for many people in achieving an aesthetic smile; thus, it must be corrected at the earliest possible stage of discoloration.
