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.
