Very common SE. I used Biotene, water, lots...and mints. Good luck.
Biotene mouth wash, and paste. I use the paste at night.
Xylitol gum and mints and epic mouth spray help too.
You also, in addition to oral care, need to lots of water......
I find it helps me, otherwise I would be waking up all the time to sip water.
ACT dry mouth mouth wash I thought was the best
I used that biotene also. I brush my teeth a lot. I went and bought a couple of baby bottles. During the night I could drink water without sitting up .
I use biotene mouth wash. They also have a toothpaste. You can find it at drug store usually.
