India, April 3 -- M ost people associate stress with headaches or fatigue, but its impact often shows up elsewhere, including the mouth. Experts say oral health is one of the first areas to reflect prolonged stress, as tissues in the mouth are highly sensitive to inflammation, hormonal shifts and muscle strain. Dr Tania Nijhawan, founder of Udana Wellness, notes that one of the most common effects is gum inflammation. "Chronic stress raises cortisol levels, which weakens immunity and increases inflammation," she explains. This can lead to bleeding gums, swelling, tenderness and persistent bad breath. Stress also often manifests as bruxism, or teeth grinding, especially during sleep. Over time, this can wear down enamel, increase sensitivity and even cause small fractures. Jaw pain, headaches and stiffness are also common signs. Another key impact is reduced saliva flow. Saliva helps wash away bacteria and neutralise acids, but stress-related dryness can increase the risk of cavities, infections and bad breath. Changes in eating habits during stressful periods can further aggravate the problem. Increased snacking, sugar intake and reliance on caffeine, along with skipped balanced meals, can weaken enamel and delay healing. Nutritional gaps may also lead to mouth ulcers and gum sensitivity.
