Any good replacement for Biotene?

I'm so bummed about this but it makes sense. I bought a new tube a month or so ago and I noticed the foaming action right away. I didn't care for it. I also noticed it stung my mouth a tad more. I can't use regular toothpaste because the mint or something burns my whole mouth. My plan will be to use my daughters Toms children's strawberry toothpaste. It doesn't sting. But it won't do anything for my dry mouth- I don't think.
