The main ingredients in Biotene products depend on the specific product, such as toothpaste or oral rinse. The active ingredient in Biotene toothpaste products is sodium fluoride. Some of the ingredients used in Biotene oral rinse are purified water, xylitol, sodium benzoate and glycerin, as noted by Biotene.
The two Biotene toothpaste products available are Biotene Fresh Mint and Gentile Mint toothpaste. Both toothpastes contain sodium fluoride as the active ingredient, and some inactive ingredients found in both are water, sorbitol, hydrated silica, glycerin, xanthan gum and sodium hydroxide.
Another product is Biotene PBF oral rinse, which can help with plaque buildup, states Biotene. Some ingredients in this product are aloe vera gel, purified water, xylitol, lactoferin and dextranase. Additionally, there is a Biotene mouth spray and gel product that contain many of the same ingredients already cited.
Biotene oral products are intended for the condition called dry mouth, or xerostomia, in which there is a lack of saliva in the mouth. When the mouth does not have sufficient saliva, it can lead to symptoms such as bad breath, problems chewing and dental problems, states Mayo Clinic.
