Best dentist in Adambakkam | Mouth Breathing vs. Nose Breathing — Dental Consequences Mouth breathing may seem harmless, but it can seriously affect your oral health over time. Continuous mouth breathing dries out saliva, increasing the risk of cavities, gum inflammation, and bad breath. It can also lead to a narrow palate, crowded teeth, and long-term orthodontic issues in children. Nose breathing, on the other hand, supports better jaw growth, proper tongue posture, and healthier oral tissues. At Dr. Akkshaya Dental & Aesthetics, Adambakkam, we identify airway-related concerns early and provide corrective solutions to protect your smile. Addressing mouth breathing early can improve your dental health, sleep quality, and overall well-being.
