Best dental care in Adambakkam | The Role of Saliva in Your Oral Defense System Saliva isn’t just water — it’s one of your mouth’s most important defense tools. It helps wash away food particles, neutralize acids, and fight harmful bacteria. Rich in minerals like calcium and phosphate, saliva also aids in remineralizing teeth and protecting against cavities. A healthy flow of saliva keeps your mouth comfortable, prevents dryness, and even supports taste and digestion. Reduced saliva (dry mouth) can increase your risk of decay, gum disease, and bad breath. At Dr. Akkshaya Dental & Aesthetics, we check not only your teeth and gums but also your saliva health, because a well-protected mouth starts with a balanced oral environment.
