The day aims to focus on the prevention and control of fluorosis.
Fluorosis is caused by long-term excessive intake of fluoride, mainly through contaminated drinking water.
High fluoride exposure can affect the teeth, bones and joints.
The Bureau of Indian Standards (BIS) safe fluoride limit in drinking water is 1–1.5 milligrams per litre (mg/L).
The National Programme for Prevention and Control of Fluorosis (NPPCF) works on surveillance, prevention, early diagnosis and management of fluorosis.
