I received this sample of Biotene dry mouth moisturizing gel from my dentist along with other products in the Biotene line. I was told that dry mouth helps lead to tooth decay among other maladies. Although I am very partial to the oral regimen that I use, I also understand what this particular condition might do to my teeth and gums. Therefore, I have begun to use this product. It does work very well in alleviating my dry mouth symptoms. This gel can be used throughout the day and at night prior to sleep. The only con I have about it is the consistency. It doesn't taste bad, but the feel of that gel in my mouth is not very pleasant. Because it was recommended by my dentist, I will continue to use it. I am hoping as time goes by, I will become immune to the feel of the gel. I can recommend this dry mouth moisturizing gel to consumers because it was recommended to me by professionals that know what work.
