Dental fluorosis . is a change in the appearance of the tooth's enamel caused by overexposure to fluoride. In most cases, fluorosis is so mild that no treatment is needed. There are many dental treatments available. See a dentist for evaluation and treatment if needed.
Depends on severity. Mild to moderate fluorosis can often be improved using a combination of remineralization/ polishing techniques possibly supplemented with whitening. More involved cases may need veneering, etc. .
