According to wikipedia,
"Tooth decay is an infectious disease, the key feature of which is an increase within dental plaque of bacteria such as Streptococcus mutans and Lactobacillus. These produce organic acids when carbohydrates, especially sugar, are eaten."
So low/no carb = low/no tooth decay. At least according to conventional wisdom.
Our western dental techniques have been honed over the last 150+ years, with dentists pulling teeth and capping them with the latest greatest compounds they have at their disposal. I, however, question an industry that is dependent on our ill-being, that is, the dental industry THRIVES on tooth decay.
"If brushing, flossing, massive fluoridation campaigns, and dental surgery were effective in preventing tooth decay, it would not get worse over time. It would stay the same, or get better. This is what I refer to as an unscientifically sound practice. If we are to examine the effects of our dental care as a society, the statistics clearly show it is a failure, as tooth decay becomes worse and worse over time."

In addition, according to the same source, "We have tooth decay today because our food supply is so poor that many foods are lacking in the fat-soluble vitamins A, D, E, and K."
I would like to add that to absorb these fat soluble vitamins, we should probably eat some fat along with our veggies/lean meat vitamin sources.
I did a quick search on MDA and couldn't find this benefit addressed. I'm sure the readership would be enthused to hear about it, as well as some science based proofs. Weston A. Price was sure on the right track.
To re-mineralize our enamel, the minerals should be exposed to the teeth directly, as swallowing calcium does not actually help rebuild our teeth. However, a tooth's direct exposure to minerals, such as calcium or fluoride. allows the enamel to absorb them.
Primally, this is likely an evolutionary advantage to cavemen, whos teeth were sorely taxed by daily life, yet likely knawed on a lot of bones/marrow.
Ideas? I'm listening for your take, Mark, I'm neither scientist, nor dentist, nor nutrition expert by any means.
