Isn't dry mouth frustrating? As most patients using amitryptiline can share, dry mouth can be a very VERY uncomfortable side effect of common IC treatments. But dry mouth can also have an unexpected consequence. The dreaded cavity. When we have a chronically dry mouth, we've lost the protection of saliva to help prevent cavities. Thus, it's important to take some extra steps to protect and comfort your mouth. Luckily, the Biotene line of products can help. I've used all of these myself and found them to be very helpful. The mouth gel worked perfectly to soothe the inside of my lips. The toothpaste helped prevent cavities and the gum was a very easy way to fight dry mouth every day. I believe that these are worth trying if you, too, are struggling with dry mouth! - Jill O.
