Oral dryness is a rather complex condition – often underestimated and, above all, quite frustrating for those who experience it. It is very common among older adults, especially women, and affects roughly a quarter of the population.
Saliva plays a crucial role in many processes: it not only keeps the mouth moist, but also aids digestion, protects teeth from decay, prevents infections by controlling oral bacteria, and makes chewing and swallowing possible.
This issue can range from a mild, temporary reduction in salivary flow – often linked to stress or nervousness – to more complex conditions that compromise oral health, involving both hard and soft tissues.
Dry mouth, also known as xerostomia, is in fact just a symptom of a range of diseases that affect the salivary glands and alter their ability to produce saliva.
Although science has not yet established a direct link between reduced salivation and aging itself, there is a clear relationship between certain medications and diminished salivary flow in older adults. Several conditions – such as Sjögren’s syndrome, diabetes, rheumatoid arthritis, and systemic lupus erythematosus – are also associated with xerostomia, as is frequently observed in individuals undergoing radiation therapy. A lack of saliva becomes an increasingly pressing problem and can be extremely bothersome for those who suffer from it. To date, none of the available saliva substitutes on the market has proven truly effective at managing the symptoms associated with oral dryness.
Cariex® was developed with this very goal in mind, in collaboration with the University of Insubria in Varese. It is a new spray that can be used at any time of day – even during the night. The product is formulated with bicarbonate to ensure excellent control of salivary pH, provide lubrication to the oral mucosa, and offer immediate relief for those suffering from xerostomia or reduced salivary flow.
When applied in the mouth, sodium bicarbonate dissolves into water and carbon dioxide in the presence of acidity. This means Cariex® can be used repeatedly throughout the day and overnight by spraying it directly onto the oral mucosa, without any contraindications or side effects. Cariex® is also effective in addressing fungal infections (such as candidiasis) and halitosis, both of which are frequently associated with reduced salivation. By regulating acidity, it helps limit cavities and dental erosion – common issues among individuals affected by xerostomia.
Cariex® serves as a reliable saliva substitute. In addition to restoring a neutral pH in the oral cavity, its combination with xylitol helps combat bacteria and infections.
The presence of hyaluronic acid further supports tissue healing, keeps mucous membranes hydrated, and reduces discomfort. It is simple to use: just three sprays whenever dryness occurs and after each meal.
