I have found that my dry mouth issue is coinciding with a change in my voice. It's becoming sort of rough as if I had been screaming or have a cold. I'm pretty sure that it is the PD since I have been on the same meds and doses for at least a year.

I use ACT dry mouth lozenges and biotene tooth paste. I think it is from the meds we take.

i had dry mouth from medications for years, and my teeth rotted. i must have had 40 root canals ! i had root canals on top of root canals. it is serious. there are some over the counter mouth rinses now that helps this problem.....please look them up, or he might loose his teeth ! i also find that if i put pressure on my throat, it would help me swallow. hope this helps, but take dry mouth seriously, please ! lu

Biotene mouth rince and tooth paste. I eat alot of fruits, grappes and watermelon. Always have gum or candy and a bottle of water is the best . My mouth gets so dry somedays i can't speak. My husband is happy those days.,

i still think that a speech therapist would be of immeasurable help.
why not ask PCP for referal, certainly won't hurt
