Fluorosis
Fluorosis: An abnormal condition (as mottled enamel of human teeth) caused by fluorine or its compounds.

Fluorosis is caused by an increased intake of fluoride.

Mild forms of fluorosis appear as chalk-like, lacy markings on the tooth’s enamel.

In the moderate form of dental fluorosis, a white opacity can be seen on more than 50% of the tooth.

Severe fluorosis results in brown, pitted, brittle enamel.

Dental fluorosis occurs during tooth development.

Permanent teeth are more susceptible to fluorosis than primary teeth.

Most critical ages of susceptibility are 0 to 6 years, especially between the ages of 15 and 30 months.

After 7 or 8 years of age, dental fluorosis cannot occur because the permanent teeth are fully developed, although not erupted.

 
 
Fluorosis ranges in severity from mild to severe.
