Biotene Dry Mouth Oral Rinse 237ml is a clinically formulated mouthwash that delivers immediate relief from dry mouth symptoms for up to four hours. The gentle, alcohol-free formula soothes and lubricates oral tissues, freshens breath, and helps maintain a healthy oral pH similar to natural saliva. As the number one dentist-recommended dry mouth brand globally, Biotene is trusted by adults experiencing dry mouth from medications, mouth breathing, CPAP use, chemotherapy, radiation, or conditions such as Sjogren's syndrome.
Why It's Safe & Effective
Unlike standard mouthwashes that contain alcohol and can worsen dryness, Biotene uses a moisturizing system built around humectants and lubricants. The formula coats the oral tissues to retain water, soothes irritation, and is free of sodium lauryl sulfate (SLS). The American Dental Association has reviewed the product under its Seal of Acceptance program, recognising its safety and efficacy for temporarily relieving dry mouth symptoms when used as directed.
Safety Information
Biotene Dry Mouth Oral Rinse is alcohol-free, sugar-free, and SLS-free. It is intended for topical use only and should not be swallowed. Keep out of reach of children under 12 unless directed by a healthcare professional. If symptoms of dry mouth persist beyond two weeks of regular use, consult your dentist or doctor, as dry mouth can be a sign of an underlying condition. Discontinue use if irritation occurs. Do not use if you are allergic to any of the listed ingredients.
The 237ml bottle contains a carefully balanced ingredient system:
• Glycerin and Sorbitol - humectants that attract and hold moisture against oral tissues
• Xylitol - a sugar-free sweetener that also helps protect against cavity-forming bacteria
• Poloxamer 407 - a lubricant that coats the mouth for extended comfort
• Sodium and Disodium Phosphate - buffers that maintain a balanced, saliva-like pH
• Propylene Glycol - a humectant that retains moisture (alcohol-free formulation)
• Hydroxyethyl Cellulose - thickener for a smooth, soothing rinse feel
Adults and children over 12 years should use approximately 15ml (about one tablespoon) of Biotene Oral Rinse. Swish thoroughly for 30 seconds and then spit out. Do not rinse with water afterwards as this can reduce effectiveness. Use up to 5 times daily, or as directed by your dentist or healthcare professional. For best results, use after brushing or whenever symptoms occur, including before bed to support uninterrupted sleep.
