The spray Brian mentioned is part of the Biotene line -- if you haven't already tried it (or the mouthwash, gel, or toothpaste), I'd definitely recommend it. I've been getting some help from Salagen over the years, but the Biotene products I've used in the past year or so have made a real difference over and above that. I noticed that the plaque wasn't building up so fast on my teeth (so I've been able to stretch out my hygienist visits a bit). Also, I sing regularly in a choir and have been doing 1 1/2 to 2 hours of singing at a time without a water bottle.
