Thanks, David. You'd mentioned Cypress before and I believe I looked into it. Must not have been an option for some reason or I certainly would have switched. Anywho I'll ask my dental office again next time I'm there. Believe I pay them 11 bucks for Prevident, but you don't need to be a CPA to do your math on the other product.
