Biotène: What It Is and How It Helps with Dry Mouth

When your mouth feels like cotton wool all day, even drinking water doesn’t help—you’re not just thirsty. You’re dealing with Biotène, a line of oral care products designed to relieve dry mouth by mimicking natural saliva. Also known as a saliva substitute, Biotène doesn’t just moisten your mouth—it helps protect your teeth, soothe irritation, and restore comfort when your body isn’t making enough saliva on its own.

Dry mouth, or xerostomia, a condition where saliva production drops significantly, often due to medications, aging, or autoimmune diseases, affects millions. It’s not just annoying—it raises your risk for cavities, gum disease, and trouble swallowing or speaking. Biotène products, including sprays, gels, mouthwash, and toothpaste, are formulated with enzymes found in natural saliva like lactoperoxidase and glucose oxidase. These help break down bacteria and maintain a healthy oral environment without alcohol or harsh chemicals that can make dryness worse.

People on medications for depression, high blood pressure, or allergies often turn to Biotène because standard hydration doesn’t cut it. It’s also common among cancer patients after radiation therapy or those with Sjögren’s syndrome. Unlike plain water, Biotène sticks around longer, giving you hours of relief instead of a quick rinse. And while it’s not a cure, it’s one of the few over-the-counter options backed by clinical testing and recommended by dentists.

You’ll find Biotène in pharmacies next to toothpaste and mouthwash, but it’s not just another rinse. It’s part of a broader approach to managing oral dryness—something that connects to other topics in this collection, like how certain drugs cause nausea, how aging affects medication tolerance, or how supplements and treatments interact with your body’s natural systems. Whether you’re dealing with dry mouth from a prescription, chemotherapy, or just getting older, the posts here give you real, practical ways to manage it—without guesswork.
