Abstract	This study investigated the fluoride content in infusions of black, green, oolong, and white tea, commonly consumed in India. Fluoride concentrations were determined using a fluoride ion-selective electrode method. The fluoride intake levels for both teens and adults are calculated and found well below the lower threshold for increased risk of dental fluorosis. Specifically, the highest observed chronic daily intake for teens (approximately 0.0115 mg/kg/day) is roughly 5 to 6 times lower than the WHO guideline's lower limit for dental fluorosis risk. Similarly, the highest observed chronic daily intake for adults (approximately 0.005 mg/kg/day) is roughly 10 to 14 times lower than this limit. Therefore, based on the chronic daily intake values the fluoride exposure for both teens and adults appears to be well within the permissible limits set by the WHO to prevent adverse health effects such as dental fluorosis.
