Dry mouth is a medical condition that affects up to 1 in 4 adults. It usually occurs when your body does not produce enough saliva. If you suffer from dry mouth, you may be experiencing some of these problems: Constant dry mouth feeling. Waking up in the night, feeling that you need a drink. Bad breath. Difficulties when speaking or swallowing. Biotène Moisturising Mouthwash helps relieve dry mouth symptoms. Dry mouth is most common in people taking multiple medications. It can also be triggered by some types of radiotherapy as well as conditions including Sjogren's syndrome and diabetes. Biotène Moisturising Mouthwash contains a mouth-moisturising system to soothe and moisturise oral tissue. Whilst some mouthwashes may be too harsh, Biotène Moisturising Mouthwash gently refreshes and provides moisturisation for people with a dry mouth. Use approximately one tablespoon (15ml) and rinse for 30 seconds before spitting out. Biotène Moisturising Mouthwash can be used up to five times a day unless instructed otherwise by a healthcare professional.
