Hi,
Nice photo of the pre-op. This should not pose as a problem for the use of the DELight or any erbium lasers. As any will do the preparation for you well if you are planning to retore with composite resin.
But I am more concerned about the other parameters, such as the depth and opaqueness of the hypoplasia, the translucency of the incisal aspect, the amount of tooth bulk in the area, the gingival asymmetry, and the expectation of the patient, that may pose as a cosmetic challenge.
Good luck and welcome to the exciting world of laser dentistry.
