Oasis was first introduced by the pharma giant GSK. Read the ingredients. Glycerin and water. They were not doing well in the marketplace with it, and sold it off for pennies on the dollar that they had invested in it, and went out and bought the Biotene Brand. Every one has preferences. If you really like Oasis, you can buy USP glycerine at the drug store for just a few dollars and make up your own for pennies a gallon. I did it when I was still in treatment at the recommendation of one of my dentists at MDACC. I've never seen the Oromoist product anywhere so I can't comment on that.
