Biotene products used to treat dry mouth are effective on a temporary basis, according to The American Academy of Oral Medicine. The AAOM states there are no thorough studies that prove any one over-the-counter product is better than another for treating dry mouth.
As of 2015, Biotene was the most recommended artificial saliva for dry mouth therapy on the U.S. News & World Report's Top Recommended Health Products list, with 78 percent of pharmacists recommending the product. U.S. News collaborates with Pharmacy Times on its Top Recommended Health Products, which uses surveys to ask pharmacists their opinions about specific products in various categories, according to U.S. News & World Report's website.
Biotene moisturizing products include oral rinses, mouth sprays and gels, according to the company. Biotene also makes toothpastes, but these products aren't specifically intended to add moisture to the mouth.
