prevention of dental caries
"I am an RN in the over 65 population, and used Prevident 5000 Plus for 3 months.  I had to discontinue it due to sensitivity, noted to be a higher risk in my age group.  The sensitivity wasn't immediate, but gradual, with increasing tongue and throat soreness and GI upset over time, until it reached a level that could not be ignored.  In the 36 hours since discontinuing it, the discomfort has reduced considerably, so it seems to be the culprit.  Unfortunately, I wasn't able to tolerate this long enough to judge its effectiveness for prevention."
