Mouth rinse that has no alcohol and works like no other I have experienced.
Flavor Name: Mint, Size: 33.8 Fl Oz (Pack of 1)
Biotene Oral Rinse mouthwash was the answer for a pre-rinse mouth wash, even before bed to leave my mouth sweet and moist. Instead of having to drink something or taste something - - - so I won't eat something before bed. It's been a miracle answer for pre-bed and dry mouth during a sleep period and wakening dryer than I want to be. I used to use Biotene "dry mouth spray", now I don't have to because the Oral mouthwash is my go to! enough said!!

Great for chemo
Flavor Name: Mint, Size: 33.8 Fl Oz (Pack of 1)
I ended up ordering this due to hearing mouth sores occurring during chemo. Using it twice a day to keep from getting the sours and it’s working great.

Works better than expected.
Size: 1 count (Pack of 1)
I really wish this was, like, a gel for running or something because the flavor is really tasty. Not too sweet, but flavorful enough to make sure you use it. It's a nice orange flavor that doesn't taste medicinal. I applied to the front and back of my teeth only and it lasted half the night. Quickly applied more and it lasted the rest of the night. I'm probably applying way too little but I genuinely just tried it so I'm not used to it yet.

Picture is deceiving .
Size: 1 Count (Pack of 2)
Picture of XYigel is deceiving as it shows two boxes. As it turns out you only get one box with two tubes in box. Picture should be changed to show one box
