ABSTRACT"Dental fluorosis," a specific disturbance in tooth formation and an esthetic condition, is defined as a chronic, fluorideinduced condition, in which enamel development is disrupted and the enamel is hypomineralized. Fluorosis can be prevented by having an adequate knowledge of the fluoride sources, knowing how to manage this issue and therefore, avoid overexposure. Controlling the fluoride intake is the best preventive measure for dental fluorosis, however when this is already installed and causing esthetic problems to the patient, many treatment techniques are recommended. This article describes an esthetic rehabilitation of a case of severe fluorosis using a new system for placing direct composite veneer, the Uveneer System (Ultradent) which simulates predictable shape and symmetry of natural teeth. In cases of severe dental fluorosis, the tooth enamel usually becomes porous and tooth whitening methods are not recommended. Therefore, minimally invasive technique of direct composite veneering using facial templates is the treatment of choice as it is easy to use, enhance clinical productivity, saves time, requires minimal preparation and is cost effective.

Introduction: Predicting the size of unerupted teeth during the mixed dentition period is a critical factor in
