It's the water. And maybe the meth.

I'm happy to defend Lubbock, but sometimes you just got to take the bad with the good:

LUBBOCK (AP) -- If you're looking for cavity-free pearly whites, search anywhere but Lubbock. A new study in next month's Men's Health magazine says this West Texas city has the worst teeth of the 100 large U.S. cities examined. El Paso (No. 95), San Antonio (89) and Dallas (87) weren't far ahead. The magazine said the best teeth could be found in Madison, Wis.; Nashville, Tenn.; and Raleigh, N.C.

Lubbock lives mainly on well water, which has more salt and flouride than lake water. Too much flouride will stain your teeth (but still protect against cavities). That, and I've met plenty of people from the area who see the British as a shining example of dentistry.
