Hi Doctor - Sometimes I get bleeding gums but have been using Corsodyl mouthwash which helps. I take Sinemet which can apparently cause brown saliva. My teeth regularly look unsightly because it gets quite thick. Is there anything else that I can do. Even tissues have difficulty moving it if I don't remember to use them constantly. It is difficult when I am out in company and I am a person who smiles a lot. (I am 66, 9st and have Parkinson's - hence the Sinemet).
