FOOD AND SALIVA: THEIR INTERACTION IMPACT ON Oral HEALTH: Exploring the Role of Diet-Saliva Interactions in Maintaining Homeostasis

Food and saliva interact dynamically to influence oral health. Saliva plays a vital protective role through its buffering capacity, antimicrobial action, and ability to promote remineralization. When food is consumed, it alters salivary parameters such as pH, flow rate, and oral clearance time, which determine the cariogenic or protective potential of dietary substances. Acidic and retentive foods may reduce salivary pH and prolong acid exposure, increasing the risk of dental caries and erosion, while saliva helps neutralize acids and restore oral balance.From a public health perspective, changing dietary patterns, including increased consumption of processed and acidic foods, contribute to the rising burden of oral diseases. Limited awareness about diet-saliva interactions further exacerbates this issue. Understanding these interactions is essential for developing preventive strategies, promoting healthy dietary practices, and implementing community-based oral health education. This knowledge supports early risk assessment and aids in improving overall oral health outcomes at both individual and population levels.
