Betty.......Have your husband try a water pic for cleaning his oral cavity. I used the water pic quite frequently toward the end of radiation and I found it both soothing and helpful in removing the "crud" from the back of my mouth and in the crevices. Also, have you tried the Biotene products yet? Biotene has both a mouthwash and a toothpaste that are worth trying out. You can find these products at the local pharmacy, and if they don't carry Biotene products ask the pharmacist to order them for you. Target just started carrying Biotene products too. Hope this helps! Sincerely Donna
