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.

Best dry mouth no taste long lasting travel
I’ve used the rinse , spray lozenges and gum, along with regular chewing gum - gargled with salt water and consumed more liquids than any human should to
no avail with dry mouth. Found this - tube is small enough to travel w and it truly is flavorless and lasts rather long
