Beauty is only skin deep. And the beauty of shiny white teeth is even less deep. Because a new study shows that fluoride forms a thinner protective shield than experts thought it did. The results appear in the surface science journal Langmuir. American consumers spend more than fifty billion dollars a year fighting cavities. When we realized that fluoride could help, we put it in our drinking water, our toothpaste and our mouthwash. But how does fluoride work its magic? Many figured that fluoride chemically reacts with the main mineral in enamel to form a thick, decayresistant veneer. But the latest research kicks that idea in the teeth. Scientists in Germany used x-ray photoelectron spectroscopy to get a detailed image of the surface of a treated tooth. And they found that the protective covering is actually only 6 centimeters thick. That's about a fifteen-thousandth as thick as a sheet of paper. And a layer that skimpy would likely be worn away by ordinary chewing.

Printed "welshes", the speaker says "protective"

Explanation: Listen for "thinner protective shield". Printed shows "welshes". They start with different letters and the spoken word is longer.

Printed "beret", the speaker says "decayresistant"

Explanation: You will hear "thick decayresistant veneer". The page has "beret", but you hear a much longer word after "thick".

Printed "mismatch", the speaker says "research"

Explanation: On the recording the words are "the latest research kicks". On the page it says "mismatch". Both words end the same two letters, so listen to the start.

Printed "ponderously", the speaker says "actually"

Explanation: Listen again to "is actually only". The page reads "ponderously", but the spoken word ends the same two letters, so focus on the beginning.

Printed "competences", the speaker says "centimeters"

Explanation: In the audio you hear "6 centimeters thick". You see "competences" on the page. The first letter matches, so wait for the whole word because endings differ.

"Langmuir" matches the audio

Explanation: "the surface science journal Langmuir" looks like an odd name. It matches the audio exactly, so do not click it.

"enamel" matches the audio

Explanation: "the main mineral in enamel" may catch your eye. It is spoken exactly as printed, so do not click it.
