If you know, you know: dry mouth is not just an inconvenience, it’s downright uncomfortable. I’ve tried several brands over the years, but Biotène is the one that consistently keeps my mouth feeling fresh without that overpowering artificial mint or gritty texture. This formula is gentle but effective, no burning, no foamy overload, and no funky aftertaste. It’s also a huge win that it’s sulfate-free and doesn’t irritate my gums like some drugstore pastes do. The mint is subtle but refreshing, and my mouth actually feels hydrated afterward (which is wild to say about a toothpaste, but here we are). If you deal with dry mouth from medication, menopause, or just bad luck, this one’s worth every penny. ✨ Pro tip: Keep a travel size in your bag if you’re heading out for the day. Nothing ruins a coffee date like feeling like your tongue is made of sandpaper. 10/10 recommend.

Dry Mouth

Size: 4.3 Ounce (Pack of 1)

I have been diagnosed with Dry Mouth, what a problem this is! My dentist recommended toothpaste for dry mouth; I selected Biotene Fluoride toothpaste for daily use. I definitely use it at night before going to bed to help keep my mouth less dry. I also use Biotene mouth wash and other products that I'll rate another time. I love this toothpaste; I believe it's helpful for my diagnosis.

Biotène Fluoride Toothpaste for Dry Mouth Symptoms

Size: 4.3 Ounce (Pack of 1)

I have been using this toothpaste on and off for a few years ever since I got a dry mouth. It is very good and leaves your mouth feeling fresh. Unfortunately it doesn't get rid of your dry mouth.

Chemical free is important

Size: 4.3 Ounce (Pack of 1)

I don’t like doing fluoride, but I do know that some fluoride is important so this is the cleanest fluoride toothpaste I could find and I use it in conjunction with a non-fluoride toothpaste I have I love the flavor. I love the fact that it doesn’t have a lot of the bad chemicals in it.

It Doesn’t Burn

Size: 4.3 Ounce (Pack of 1)

Toothpaste burns my mouth. Idk why. Started during menopause along with the many other things that changed about myself. I do like it. It doesn’t burn. But, it doesn’t give me that clean feeling.
