Saliva Is a Necessity: Why It Matters
Saliva lubricates oral tissues, helps with swallowing and speech, begins digestion, buffers acids, and contributes minerals that help protect tooth enamel.
Low saliva changes the mouth
Without enough saliva, people may notice dryness, burning, difficulty swallowing, taste changes, or a higher cavity rate.
Hydration is only part of the answer
Drinking water can help comfort, but persistent low saliva may need evaluation of medications, medical conditions, or salivary-gland function.
Dental prevention may need to be intensified
Patients with chronic dry mouth may need individualized fluoride, home-care, diet, and recall recommendations.
