The ingredient descriptions refer to the general characteristics of the individual ingredients. They do not imply specific product claims or clinical outcomes, unless stated otherwise.
Role: Natural mucosal protection & lubrication
Olive oil polyphenols help form a protective layer over oral tissues, supporting lubrication and comfort when saliva is reduced. They are particularly valuable in dry, irritated mouths and in people undergoing medical treatments that affect the salivary glands.
Role: Moisture retention, saliva stimulation & oral comfort support
Betaine helps oral tissues retain moisture by supporting hydration at a cellular level, while Xylitol stimulates natural salivary flow and supports a healthier oral environment. Together, they help improve comfort in dry mouths by both enhancing moisture and encouraging the mouth’s own protective mechanisms.
Role: Sensitivity support, enamel protection & cavity prevention
Potassium helps reduce dental sensitivity, which is common in people with dry mouth due to exposed or weakened enamel. Fluoride strengthens enamel and helps protect against tooth decay, a known risk when saliva levels are reduced.
Role: Mucosal soothing, tissue protection & moisture support
These ingredients work together to help soothe dry, sensitive oral tissues, support moisture balance, and protect the oral mucosa from becoming cracked or irritated. They are particularly beneficial for people experiencing ongoing dryness, inflammation, or treatment-related sensitivity.
