Frequently Asked Questions

What causes dry mouth (xerostomia)?

Dry mouth occurs when saliva production is inadequate for comfortable oral function. The most common causes are: medications (over 400 medications list dry mouth as a side effect — particularly antihistamines, antidepressants, antihypertensives, and anticholinergics), radiation therapy to the head and neck (damages salivary glands), Sjögren's syndrome (autoimmune destruction of salivary glands), ageing, dehydration, and mouth breathing during sleep.

How is Biotène Spray different from just drinking water?

Water temporarily relieves dry mouth by providing moisture but evaporates quickly and does not provide the lubricating film that saliva does. Biotène's formulation contains a moisturising polymer system that adheres to the oral mucosa, forming a lasting lubricating film — similar to the mucin glycoproteins in natural saliva. This provides sustained relief between uses rather than the immediate but short-lived relief from water sipping.

How often can I use Biotène Spray?

Use as often as needed for comfort — the formula is safe for unrestricted use throughout the day and night. Many people spray several times an hour during the day and keep it by the bed for night-time relief. It is sugar-free and alcohol-free, so there is no harm from frequent use.

Does Biotène help prevent tooth decay in dry mouth?

Biotène Spray helps relieve the discomfort of dry mouth but is not a substitute for fluoride treatment in caries prevention. Dry mouth significantly increases cavity risk because saliva's antimicrobial and remineralising functions are impaired. Use Biotène Spray alongside fluoride toothpaste, fluoride mouthwash (Biotène also makes one), and regular dental check-ups for comprehensive dry mouth dental care.

Is Biotène suitable for people on cancer treatment?

Yes — Biotène is specifically recommended for people experiencing dry mouth from chemotherapy and head/neck radiation therapy. The alcohol-free, gentle formula is appropriate for sensitive, mucositis-affected oral tissues. Consult your oncology team about a comprehensive oral care protocol during treatment.
