Tea may easily contain 5 to 10 times as much fluoride as fluoridated water.

2. TOTAL intake is what determines fluoride toxicity. This has been established since the 1930s when fluoride was discovered to be the source of "mottled enamel" - dental fluorosis.

In 1991, total intake among adults in fluoridated areas in the US was estimated to be up to 6.6 mg/day. (US PHS, 1991)

"The daily intake of most adults is about equally divided among food, drinking water, beverages, and mouthrinses." (U.S. Dept. Health & Human Services, Report on fluoride benefits and risks. MMWR Recomm Rep. 1991 Jun 14;40(RR-7):1-8. PMID: 2051975.)
