I have never had mouth sores. When I have a tender spot on my tongue or gums I brushed my teeth with baking soda and its gone. A friend of mine who was getting his chemo at a different hospital was told to use this as it neutralizes the acid in the mouth. Now, I use baking soda instead of tooth paste as I like the way it makes my mouth feel. Hope this helps some of you. Hugs, Sandy

Another thing that may help with mouth sores is Aloe Vera Juice. It is a very healing, soothing juice and it healed my mothers mouth after Chemotherapy treatments of Xeloda. It is worth a try for anyone who is wondering. I agree too that Baking Soda is a good thing to use also.
