Dental fluorosis is one of the most common colour disorders which results in discoloured teeth, with white or brown spots. The aspect may be different depending on the severity of the fluorosis and the degree of the damage of the enamel and dentine. This article describes different approaches to treat a dental fluorosis. It is suggested that mild-to-moderate fluorosis be treated by microabrasion and bleaching, while severe fluorosis, with loss of some surface enamel, is managed by veneering and crowning.
