I decided to try this gel after finishing an expensive brand recommended by my Dentist. The other gel was in a tiny bottle for double the price. I like that this one is cost effective, and I also enjoy the taste, which is minty overall. As far as helping with dryness, I'm on the fence about both products. My mouth is SUPER dry though, due to medications, so there may not be any effective treatment out there for my Tundra mouth issues. The downside to this one, is that it's very thick and can come out in a blob, which is wasteful. I wish it came in a pump so it would dispense only what's needed. Overall, I recommend trying it for dry mouth, and I'll continue to buy it unless I find something that provides more relief.

This was recommended by my dentist who gave me my first tube. I use xylomelts for dry mouth which works but because they are hard they make my gums sore.
