The BDA spokesperson said that tea was also a good source of fluoride which can help to protect the teeth.
Fluoride salts can carry fuel in chemically-stable forms that can be passively cooled without pumps driven by emergency power generation.

The report says scientific evidence suggests "almost every proven method to prevent decay includes delivery of fluoride to teeth surfaces".

Dentist Bill Dorfman, the Los Angeles-based founder of tooth-whitening company Discus Dental, scoffs at the many fluoride-free brands on the market.
Portland city leaders say they were spurred toward fluoride when a citizens' group noted rising tooth decay among low-income and minority children.
Many U.S. cities began adding fluoride to water in the 1950s after evidence showed it strengthened teeth, but Portland always held out.
Brewer Larry Crouse and a business partner posed in boxer briefs with the words "No Fluoride in My Beer" across their bare backs.
Could there be a fluoride variety superior to my old standby?
The greenhouse gases surveyed include not only carbon dioxide but also methane (CH4), nitrous oxide (N2O), ozone (O3), and fluoride-containing gases that contribute to climate change.

The level of concentration in water had a "negligible effect" on people's uptake of the fluoride ion - responsible for increased risk of fractures, they said.
The oxide (which comes from an ore called coltan) is converted to a fluoride using hydrofluoric acid, and the fluoride is then reduced with liquid sodium.
The MRC researchers said increased fracture rates could not be blamed on concentrations of fluoride at levels found in water supplies, even when additional fluoride was added.
That's achieved by brushing twice a day with fluoride toothpaste.
Elevated fluoride contents in wells tapping the Argentinan part of the aquifer probably originate from the sandy deposits of the Solar Formation intercalated in the Cretaceous Serra Geral basalts.
Furthermore a correlation of hydrochemical parameters, such as fluoride concentrations and total dissolved solid contents, with main tectonic structures within the basins was carried out for the whole aquifer system.
There was no difference in the chance of hip fractures for those people looked at in the study regardless of how long they had been exposed to higher fluoride levels.
For instance, the idea that the Navy's sonar systems are harming whales is about as well based in fact as the 1960s fear that fluoride in our water was poisonous.
Quantities of sewage are poured into it daily, 95% of which is untreated, and it is also a depository for industrial effluents, chemicals from farm runoffs and arsenic and fluoride contamination.
The fight-fluoride campaign attracted a big organic-food vendor.
Made of a material known as polyvinylidene fluoride (PVDF), this belt produces an electric charge whenever low-speed airflow passes over it and causes it to vibrate -- a result of that vaunted piezoelectric effect.

To dig up the raw material, process it, convert from oxide to fluoride to metal to iodide, to mix it with mercury, make their own light bulbs, all of this within each of the different 192 sets of national boundaries.
Yes I have seen the advocacy for Liquid Fluoride Thorium reactors and there are some apparent tantalizing advantages over current Uranium reactor designs like ability to burn plutonium as a starter fuel, less production of transuranics, higher fuel burn efficiencies, etc.
