Dental fluorosis is caused by excessive amounts of high concentration fluoride exposure during tooth development. It often appears as faint white streaks on enamel in most mild cases and in the most severe cases will appear as a brown mottled spots on the teeth. Usually it is a combination of fluoride sources which lead to the over exposure. Children between the ages of 1 – 4 are at critical age of exposure. A child is no longer at risk after the age of 8 because all of the teeth have been developed already.
Since fluorosis is permanent and will not go away over time there are some ways to reduce its appearance. Most cases of fluorosis are mild and cannot be seen easily, but for more severe cases there are options such as bonding resin on fronts of teeth affected or veneers. Unfortunately, teeth whitening will often make the stains and white streaks have an almost chalky appearance which will still stand out from the regular tooth colour. The best way to find a solution which will work best for your specific case is to meet with a dental professional.
