It has been four years and ten months since my surgery. My jaw bone was replaced with a portion of my left leg bone. Afterwards I had radiation treatments. Dry mouth is a problem at night and has been since I began radiation treatments. I have tried biotene products, warm salt water, baking soda and water,and Colgates peroxyl. The Peroxly works best if I use it before bedtime and in the morning after getting up. I have found it is most helpful in getting rid of the thick mucous that you get during the night. Now for the amazing experience I had. I am from Arizona and we have a very low humidity climate. This September and early part of October I spend in Northwest Arkansas. I did nothing different than the routine I do in Arizona. Ate the same type of foods etc. In about three weeks I noticed a big change in the feeling in my mouth. It didn't burn nor did my tongue tingle. Even taste became better. The only thing different that I can figure helped me was the high humidity. I was good until I was back in Arizona for about ten days and the ole symptums returned. Anyone else noticed any change with the higher humidity?
