I get dry mouth all the time. I have not tried Biotene but my physical therapist told me about it. I take Ditropan for my bladder and that causes dry mouth. Like others, I keep water by me all the time and drink a lot of it. Sometimes flavored water helps to quench my thirst and dry mouth, especially lemon water.

This may sound odd but I had a mouth sore right by a tooth not too long ago. I tried everything I could think of to get rid of it. Someone recommended that I try rinsing my mouth with coconut oil. I didn't have any coconut oil and was feeling desperate so I used olive oil and rinsed my mouth with it. Not only did the sore ease up but so did the dry mouth. I didn't have problems with it for the rest of the day and night. I haven't tried it again and actually forgot about it until just now so I don't know if it was a coincidence or if it really does work long tern.
