Bleaching has been suggested by several authors in order to treat the unaesthetic aspect of dental fluorosis. Many results are, however, unsatisfactory. A different method, based on the structural characteristics of the fluorotic tooth and the organic and exogenous nature of fluorotic enamel stains, includes three principal stages: 1--enamel etching with 12% HCl in order to eliminate the posteruptive calcified layer that covers the fluorotic enamel surface and to denude the microcavities containing the organic elements; 2--application of pure manufactured sodium hypochlorite to remove these organic stains; and 3--filling the chemically opened microcavities with a light-cured dental adhesive to provide the tooth with a smooth and even surface and to prevent restaining. To improve the aesthetic aspect of intensely discolored teeth, it is possible to use a variety of tints available in several composite resin kits. Teeth with a rough enamel surface react more positively than ones with a smooth surface. The enamel adhesives provide better results than the amelo-dentinal ones.
几位作者提出了漂白法来治疗氟斑牙的不美观问题。然而，许多结果并不令人满意。一种基于氟斑牙的结构特征以及氟斑牙釉质染色的有机和外源性本质的不同方法，包括三个主要阶段：1. 用12%的盐酸蚀刻牙釉质，以去除覆盖氟斑牙釉质表面的萌出后钙化层，并暴露含有有机成分的微腔；2. 应用纯的人造次氯酸钠来去除这些有机污渍；3. 用光固化牙科粘合剂填充化学打开的微腔，以使牙齿表面光滑均匀，并防止再次染色。为改善严重变色牙齿的美观，可使用几种复合树脂套件中提供的各种色调。牙釉质表面粗糙的牙齿比表面光滑的牙齿反应更积极。牙釉质粘合剂比釉质 - 牙本质粘合剂效果更好。
