Hi Susan............Have your Mom try Biotene Mouthwash to rish her mouth with. I used this ALL the time to rid my mouth of the thick ropey saliva that would coat my mouth and throat. Not only did I find it soothing, it was good at cleaning my oral cavity. Biotene can be found at your local drugstore, if you can't find it, ask the pharmacist about ordering some. I purchased mine at Walgreen drug, but I don't know if you have Walgreens in your area. Oh, another thing I used was a water pic. I also found this very soothing in my oral cavity and it was good at getting the crud out. Good luck! Sincerely, Donna
