Hey, they work, period!! As a result of Radiation treatments on my throat, I lost some saliva activity. DRY MOUTH! One of these discs last me for about four hours at night. Thanks.
Excellent for overnight relief from dry mouth. Found one on each side of mouth does the trick. Coming back for more. Purchased one pack so will be purchasing more.
i can't believe i never knew about these! I like to use them while i'm at work and they work for keeping my mind off my usually dry mouth and on my projects instead! Seems to keep my breath fresher to somehow
