A young lady presented with heavy brown stain on her Upper Canine, which is very obvious when she talk or smile. Therefore, she asked for solution to remove it or cover it, in order to make the smile more pleasant.
The brown stain is known as dental fluorosis. In most cases of dental fluorosis, it is presented with white patches scattered around the enamel surface of teeth. Dental fluorosis characterized by hypomineralization of enamel caused by ingestion of excessive fluoride during enamel formation. It appears as a range of visual changes in enamel causing degrees of intrinsic tooth discolouration.
In her case, we proposed to start with conservative treatment by performing micro-abrasion to remove about 0.2mm of the affected enamel layer, follow by whitening the teeth with 35% Carbamide Peroxide. If this conservative treatment not give a satisfy result, then cover the teeth with Veneer may seems necessary.
The result of the treatment is very encouraging. Although still have mild degree of discolouration, the young lady is satisfied with it.
