I have only tried another version of this, but the biotene version is water based and not oil like I tried. I put a smudge of this on my finger and suck it off. I assume that's the right way, the tube is a bit small though. But it does last a pretty long time. Basically its glycerin in a form of a gel, and its tastes sweet, does it work? Yeah, more or less. I place it on the roof of my mouth and dip from there, but when done, i still need a drink. But its helpful if your mouth is dry and you keep having to drink a ton of water to get to sleep. So I get a bit of this. I'm hoping to find a way to make it myself though.

Good, super useful - worth the money

Works well. I use it with a mouth guard that helps with grinding my teeth and this product seems to protect my gums.

Biotene WORKS

Dry mouth happens at night because of my cpap. My dentist recommended Biotene and it was a great relief for my dry mouth problem. Highly recommended!

A Gel that's convenient and effective

After using the Biotene gel for several nights, I am happy that I bought it. The product is convenient to use and effective. My dry mouth was leaving my tongue parched at night. This gel solved my problem. I highly recommend it.

It’s ok in a pinch!

This works good in a pinch; however, I don’t see that it provides a significant timeframe of moisture. It wears of quick.
