I couldn't use the waterpik early on because my mouth was so sore. The mouth now four months since radiation is better but the thick mucous still persists. I use a soft toothbrush to get it off the tongue and the roof of my mouth. I have to so this many time during the day. If I talk alot the mucouc turns to a thick foamy mess. Being that I have also lost my swallowing function I have to have a place to spit. At night I dry out pretty much so I use a vaporizer and "breath rite" strips on my nose to allow better breathing thru my nostrils instead of my mouth.
