Do we need to review some biology quickly? It doesn't matter that the food may just 'touch' your teeth, your body absorbs everything you intake. The primary purpose of the small intestine is to absorb materials that were ingested and subsequently distribute those materials to the rest of the body.
Mosts MSDs show that organs such as the liver and kidney's are always affected by digestion of hazardous substances; and quite a bit of the time you have the PNS (peripheral nervous system) and CNS (central nervous system) becoming damaged.
But, wait, if the hazardous substance only came in contact with your teeth, then why would the spinal cord become damaged.
For instance methanol (MeOH) has a tendency for the eyes to become target organs, yet if you drink MeOH or have it come in contact with your skin over a porlonged amount of time, it will effect your eyes. You don't have to use it as an eye wash.
I am not 100% sure on this part though, but I believe the P- ion will bind with calcium due to it's electronegativity. I know for a fact that F- is the most electronegative element and will readily chelate calcium out of your body, hence why HF acid is probably the most dangerous acid. So, P- may do a simalar job of chelating the calcium.
I have also seen video of a tooth in a beaker of soda become dissolved over a short time (30 minutes I think). The pH of most soda is something like 2 or so which is about what your stomach is. However, luckily, we have buffers in our saliva that help save our teeth.
