Better than regular mouthwash
Flavor Name: Fresh Mint, Size: 16 Fl Oz (Pack of 1)
Works better than regular mouthwash. It's not miraculous but it helps dryness.

I use it two times a day. I have very sensitive teeth and gums. It works very well. It is not too strong. Does not burn.

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.
