They are right. 1 MOhm water will jack the minerals off your teeth. OP would be lucky to not have cavities forming right this second.

i do have cavities on back of my lower jaws; however, it's not due to RO water. should RO water is causing this, the damage distribution should be uniform -> my other teeth should be equally damaged. i still have other teeth intact, no holes, despite using ro water for 8 years or so. i think there's the cause of my holes. i had wisdom teeth very late in age. my brushing pattern wasn't sufficient. moreover, i was addicted to oatmeal power drink and didn't brush after. those sugary flakes seem to linger on my back jaws. yudkin book, "pure, white and deadly" discusses this. children who drink sugary vs eating candies. same sugar; however, those eating candies get more cavities simply because candies stick between teeth ... think twinkies on interesting part of the book is about the slave in sugar plantations. they did eat raw sugar; however, the slaves didn't get the same disastrous level of disease as the masters, who eat refined sugar.

  Cavity damage isn't uniform though. It depends on location of exposure and the way the mouth salivates. It makes sense that the cavities are toward the back of the tongue. Anyhow, I would be careful. Just get a potassium chloride rock and throw it in the water. No biggie.

How could that be the case? Tap water is nowhere close to mineral saturation. It should make an astronomically small difference. If anything, it could be less corrosive due to the higher resistance. I do see a possibility for it to be slightly more corrosive in pipes under specific circumstances, due to the lack of anything forming a passivating layer on the long run. But for teeth I have a hard time believing this.

  Are you kidding me?! Tap water has to go through dirty city pipes. Of course it's saturated with minerals. Not only that but Fluorine or Chlorine or whatever halogen they choose to kill the bacteria and protozoans with.

    What I meant with saturation is the state when no more minerals can be absorbed.

      Dissolution is based on concentration of existing solute. This isn't a binary effect of complete saturation like you suggest. Pure water has enough diffusion pressure to cause significantly more dissolution of a tooth's mineral lining than hard water. Diffusion pressure of pure distilled water is 1236 atm. See DPD: https://en.m.wikipedia.org/wiki/Suction_pressure https://en.m.wikipedia.org/wiki/Suction_pressure Quote on quote: "If some solute is dissolved in water its diffusion pressure decreases. The difference between diffusion pressure of pure water and solution is called diffusion pressure deficit (DPD)."
