Someone mentioned fluoride, so I thought I'd add this. I'm not using saliva encouragement as a replacement for fluoride gel. I'm still using Omni Gel Dental Treatment 0.4% stannous fluoride once a day. During my last dental visit, the hygienist told me to consider Enamelon products, which in include oral gel and toothpaste. She said both contain stannous fluoride and both can remineralize. I ordered the toothpaste, but I'm sticking with my current gel until I can find out more.
