Best dentist in Adambakkam | How Night-Time Mouth Dryness Damages Teeth Night-time mouth dryness reduces saliva flow, which is essential for protecting your teeth. Saliva helps neutralize acids and wash away harmful bacteria while you sleep. A dry mouth increases the risk of cavities, enamel erosion, and gum disease. Mouth breathing, medications, and dehydration are common causes of night-time dryness. Patients may also notice bad breath and a burning sensation in the morning. Over time, untreated dryness can silently weaken teeth and gums. Using the right dental care products and treating the root cause is crucial. At Dr. Akkshaya Dental & Aesthetics in Adambakkam, we help identify the cause of dry mouth and provide personalized solutions to protect your teeth and overall oral health.
