Adnkronos (Adnkronos) – "Hydration is one of the main factors supporting saliva production and the physiological balance of the oral cavity. Adequate water intake throughout the day helps keep the mucous membranes hydrated, promotes the protective function of saliva, and supports long-term oral health." This is what Alessandro Zanasi, an expert at the Sanpellegrino Observatory and a member of the International Stockholm Water Foundation, wrote in a statement, noting that when it comes to oral health, attention often focuses on dental hygiene, nutrition, and regular checkups.
However, there is a simple and natural daily gesture that often goes unnoticed: drinking water.
Referring to published literature, the note explains that hydration plays a key role in promoting saliva production, our mouth's first natural defense mechanism. Saliva helps protect teeth and mucous membranes, becoming a true ally of our smile.
It acts as a lubricating fluid, buffering acidity and facilitating swallowing and the initial digestive process. Drinking too little can disrupt this balance: reduced salivation can promote dryness in the oral cavity and make you more vulnerable to irritation and tooth decay.
Throughout the day, the body loses fluids through breathing, sweating, and metabolic activities; if these losses are not adequately compensated for, the function of the salivary glands can also be affected.
In particular, air-conditioned or heated environments, caffeine consumption, and a hectic lifestyle can worsen the sensation of dry mouth. Maintaining an adequate water intake, which consists of 1,5 liters per day for an adult—the note concludes—is therefore a small daily habit that can make a big difference, not only for the body's overall well-being, but also for a healthy, bright smile.
